The Biggest Thing Since the Light Bulb
- lighthazard 14y agoLife: 22.8 years * based on 3 hours /day
- ck2 14y agoThis is huge if only because a LED bulb company finally put its warranty where its mouth is. Every other bulb, ie. the expensive Phillips bulb, only gives a 3-4 year warranty I'd definitely give this a try @ $10 It's also dimmer compatible which is a big plus for me with X10 control, CFL cannot dim. If this bulb does not operate for 10 years (based on 6 hours per day / 7 days per week of normal consumer use) from date of purchase when used as directed, return the bulb [...] Cree will send you a replacement or at Cree’s option refund the original purchase price. ps. you can use ebates.com to get a $5 off $50 Home Depot coupon and 3% cashback which will reduce the cost on these
- mullr 14y agoI wonder what the expected warrantee redemption rate is for these things, for all of them that fail. Say you had it for 5 years and it failed. If it was me, I'd just go out and buy another one. Perhaps a different brand, but I probably wouldn't think that far ahead. For something at this price point, does anybody really USE the warrantee?
- ck2 14y agoFor $10, I would return it for the next ten years. Problem is it costs $1.70 to send via USPS mail, but maybe you could wait until you had a couple to send back.
- Cthulhu_ 14y agoAnd that's exactly where they're going here; offer a long warranty and easy returns, while producing a product that's cheap enough (definitely in 5 - 10 years) that people won't actually bother with it. It's what happens with mainstream consumer electronics; 3 years warranty, sure, but would you return a $30 machine to the webshop you got it the cheapest to claim that three years later?
- ghshephard 14y agoI know some people who write the date on their light bulbs (incandescent, no less) and switch brands if the bulbs burn out too quickly. For $10/bulb, those people would likely get their refunds, but I agree - for bulbs lasting five years, not a lot of People are going to be redeeming this warranty. The good news, is that Cree probably has a very good idea what the failure rate will be, and it's likely that the vast majority of these Lightbulbs are going to last more than 10 years.
- mc32 14y agoI agree. I bought a Sylvania and while I like it, specially the 75W equiv, it's a bit pricey ($35). I'll be on the lookout for these next time I'm at a home improvement store. Also hope they come out with 75W equivs. Love the crees in torches as well.
- dangrossman 14y agoAll LED bulbs I've seen say dimmer compatible, but most really aren't. I have comparably-priced LED bulbs from Home Depot already, and any less than 90% power they buzz loudly.
- thisone 14y agoHeh, that's completely the opposite of my experience. I've seen extremely few LED bulbs that say they are "dimmable" and I've been looking around a fair bit as I'm transferring all the lights in the house over to LED if on-time matters and CFL if it doesn't. (in UK I should note)
- ck2 14y agoAlmost all led bulbs I've tried (admittedly not the expensive ones) have failed in my dimmers.
- zokier 14y ago> It's also dimmer compatible which is a big plus for me with X10 control If you have already X10 system in place, wouldn't X10 compatibility be more ideal than dimmer compatibility?
- ck2 14y agoX10 has dimmer modules. It's basically a dimmer with remote control.
- zokier 14y agoYes, but the point was that it would be far more optimal to have the control signals go directly to the LED driver circuitry instead of chopping up the mains voltage and hoping that the LED driver will handle it. Computer analogy: Imagine you would like to adjust the performance/power of your computer. You could plug the computer to a dimmer and then engineer the computer to adjust itself according to the dimmed mains voltage. Or you could route the X10 signal to the computer and use it to adjust the power profile. Which solution seems more reasonable to you?
- nitrogen 14y agoX10 is way too slow and really needs to go away. Instead, bulbs should include a more modern standard, which Hue does (at 6x the price).
- zokier 14y agoThat is bit besides the point. Personally I think PLC based system would make most sense for home automation, considering that a large portion of the devices are mains-powered anyways. And if you design the system really cleverly then having the same network extend wirelessly to those nodes where PLC is unsuitable.
- nitrogen 14y agoPowerline control is fine, but X10 is simply too slow to handle the demands of a modern house with advanced automation. My own system uses DMX-512 and Philips Hue lights (which use Zigbee Light Link). Some of my customers use X10, but the performance is not nearly as good since it can only transmit 20 bits per second.
- unwind 14y agoApologies, but: pet peeve alert! The Dutch electronics multinational is actually called "Philips", with a single 'L' in the middle. See also http://en.wikipedia.org/wiki/Philips http://en.wikipedia.org/wiki/Philips. I often see it written with two 'L':s, I think it's mainly due to pronunciation by English speakers.
- urza 14y agoThe bulb will probably operate in 10 years, but most likely it will loose its brightness over the years, because I doubt that it can be properly cooled..
- gregable 14y ago$10 seems like actually a very good price for LED bulbs, especially if they work as advertised. Add in a 10yr warranty and it seems like a no brainer. Cree isn't a little startup or anything either, it's an established LED manufacturer.
- otibom 14y agoOff topic, but am I the only one to find the automatic scrolling very annoying ? Don't move the page on my behalf.

- ck2 14y agoNot just you, YesScript or NoScript solves this problem for me though. https://addons.mozilla.org/en-us/firefox/addon/yesscript/ https://addons.mozilla.org/en-us/firefox/addon/yesscript/
- Ramp_ 14y agoThe site is so annoying I didn't even read the content. Terrible.
- DeepDuh 14y agoI seriously wonder what programmer / manager looks at this and thinks 'Yeah that's awesome, let's keep this!'.
- leetrout 14y agoDefinitely not off topic for a site full of engineers and designers. It is a huge pain to navigate, especially when you get to the 3 bulb types near the bottom and as you scroll you accidentally hover over one of the bulbs.
- ozgung 14y agoI think it's that annoying because there is a mismatch between your intention (scrolling the page incrementally) and its reaction (moving to the next "slide"). It acts out of your control.
- grey-area 14y agoNot just you, it's annoying to have scrolling behaviour taken over by the website. Also, scrolling down != changing page, but their js is treating it as changing pages, so the back button is broken.
- ars 14y agoThis page has GOT to stop moving!! GRRRR. Who decided this was a good idea?
- logn 14y agoI also had to just press the back button 8 times to get back here.
- toast76 14y agoAgreed. Since when did scrolling become a page navigation? If I'd clicked a title, then sure do a hash change, but otherwise leave my URL alone. On top of that, clicking an anchor (which on any normal website would take me _instantly_ to that point in the page) scrolls slowly from top to bottom. Do that a couple of times and watch what happens when you hit the back button a few times... shoot me now.
- riffraff 14y agoto whomever is building website thinking "oh, I know where my user wants to be in the page": please take a deep breath and rethink your assumptions.
- rciorba 14y agoSadly I only have one up-vote to give. I compulsively scroll up-down and the page keeps scrolling me back to the viewport it thinks i want. While this take over the user's scroll thing is a neat trick it reminds me of when much of the internet was flash. It's my fcking browser, let me control the fcking scroll.
- belorn 14y agoI wonder what you are talking about because ... A ye, must be something that Ghostery or No script (js enabled) is preventing. Or ad block. I guess I don't know what is preventing me for having a bad experience, but I guess one of those 3. update Found the issue. JavaScript was disabled on the page. Sorry if my post mislead.
- gt565k 14y agoHah... the light bulbs today are the biggest scam ever. Light bulbs made 100 years ago are still working today, because the materials used, more precisely, the filament, was made out of a lot more durable materials. However, companies quickly realized that if ligh bulbs lasted so long, no one would buy new light bulbs. If you have not seen the light bulb conspiracy, please watch it on youtube. http://www.youtube.com/watch?v=4WPrTk90VZM http://www.youtube.com/watch?v=4WPrTk90VZM Planned obsolescence... You can buy long lasting light bulbs made with stronger filament, of course they are no LED, but will probably last a century.
- vailripper 14y agoEven still, that doesn't do anything about the energy savings you get with LED...
- gt565k 14y agoI'm just saying. Plus, I still don't understand why people care about light bulbs saving energy. The majority of electricity consumed in a houses and apartments comes from the AC unit, refrigerators, heaters, TVs, and computers. Implying that this light bulb will save you money would imply that you're terrible at keeping your lights off, and thus you should save money by continuing to exercise bad habits that cost you money. The way I see it is, the problem with energy consumption in households usually stems from the consumer' habits, and not so much from the equipment used. People are terrible at turning the lights off. Just like my roommates. If I don't turn the lights off, no one else does.
- bfung 14y agobingo! You've hit the nail on the head on all fronts. But light blubs and the act of turning on and off lights are very tangible to the average person, compared to thermostat programming. Awareness itself is a big step, sadly. Disclosure: I work for an energy efficiency company and basically telling people to do turn off / lower the settings is our business: opower.com.

- nikcub 14y agoCree is one of the firms from the Wired feature on LED lightbulbs in the August 2012 issue: http://www.wired.com/magazine/2011/08/ff_lightbulbs/all/ http://www.wired.com/magazine/2011/08/ff_lightbulbs/all/
- ars 14y agoHmm, actually beats a CFL - although not by much, the CFL uses 11 watts, this uses 9.5. But the CFL costs $1, this costs $13. It lasts 3 times as long, but still - unless you really need great color accuracy (i.e. CRI), I can't see myself buying this. (I'm comparing to a CFL with the same warm color temperature.) Edit: CRI of 80! That's worse than the CFL I'm comparing it to! Why would anyone want to buy this? The small boost in energy efficiency is not worth the $10.
- adinb 14y agono mercury hazard - you don't have to vent your house and worry about mercury exposure if a bulb breaks.
- ars 14y agoIn my entire life I've broken exactly 1 CFL - and I was a kid at the time. And you don't have to vent your house, that's an urban legend. The mercury is elemental mercury which isn't very toxic, and extremely poorly absorbed on top of that. (The toxic mercury is organic mercury. Some elemental mercury will be converted, which is why people worry about it - but it won't be converted in your house.)
- m_for_monkey 14y agoElemental mercury is very toxic, inhaling its vapor is dangerous. https://en.wikipedia.org/wiki/Mercury_(element)#Toxicity_and_safety https://en.wikipedia.org/wiki/Mercury_(element)#Toxicity_and...
- dietrichepp 14y agoMERCURY IS TOXIC. DO NOT TELL PEOPLE THAT IT IS NOT TOXIC. Both elemental mercury and "organic" mercury are toxic (I assume you mean "organic mercury compounds", since mercury is never "organic"). The relative toxicity of mercury does depend on the compound. Dimethylmercury is exceptionally poisonous: it will go right through latex gloves, skin, and the blood-brain barrier; minute concentrations will kill you. Metallic mercury is much less toxic, but when you inhale mercury vapors it gets absorbed rather well into your circulatory system. The amount of mercury in a CFL is very low. If I broke a CFL, I would make sure to ventilate the room for a few hours, but I would not be worried. However, it is downright irresponsible to tell people that elemental mercury is not toxic.

- beachstartup 14y agoi use one of these to walk my dog. it's ridiculously bright and it's laughable when you see someone using a 'normal' flash light which basically just looks like someone using a zippo lighter to light their way. bought 2 for the office and 1 for the car too. mine use regular AA batteries not the expensive high voltage rechargeable ones. edit: this comment is about the same cree LEDs except in flashlight form.
- ars 14y agoYour message is offtopic. Delete it before you get tons of downvotes, and your account gets banned. Next time actually read the linked article before posting.
- pcl 14y agoIt's not all that off-topic. Cree does make LED flashlights, presumably with closely related technology. If they do a good job there, that's a good indicator that they might do household LED bulbs well also.
- easytiger 14y agopersonally i think you are being an asshole... he just forgot to mention he was talking about something else in their product range. It is in that context, still on topic.
- ars 14y agoHow nice. Note that I did not downmod him, but at least 3 other people did. I was warning him before his account got hellbanned. But I guess you see prefer to see bad intent.
- beachstartup 14y agothe article is about cree LEDs i use a cree LED in a flashlight to walk my dog if i get 'hellbanned' for this comment, i'm not really sure what to say. i probably won't try registering again because that's just really mean.
- Void_ 14y agoWhere can we get these in Europe?
- FoeNyx 14y agoI don't know for this brand, but there are Phillips or Toshiba LED light bulbs in mall for years. (caveat : not as cheap)
- lucaspiller 14y agoI haven't heard of those before. All I've seen on the high street are CFLs and halogen bulbs. The prices seem pretty good on Amazon: http://www.amazon.co.uk/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=Toshiba+LED http://www.amazon.co.uk/s/ref=nb_sb_noss?url=search-alias%3D...
- millstone 14y agoThis site hijacked my back button as I scrolled. Please don't!
- charonn0 14y agoI'm not seeing what's so special about these bulbs.
- com2kid 14y agoAm I the only one not impressed by these 60 watt bulb replacements? 60 watt bulbs leave my entire place looking dim and depressing, sure good colors are nice, but if I can't see anything, what does it matter? My light fixtures were designed for a few 100 watts, replacing them with these 60 watt LEDs may save me power, but at the cost of my eyesight! I am more interested in true 100, or even better, 150 watt, replacement bulbs. Get those in a good package size with some energy savings!
- ricardobeat 14y agoUse a pair of them for each fixture? At $20 it's still cheaper than a single lower power LED bulb from other brands.
- jswanson 14y agoIt's amazing how widely people vary on light. It's observable across major cultures, or even different families. A Japanese IKEA I went through recently had a display which would allow you to switch between 'Japanese' style lighting' and 'Western' style, with western style being dimmer, and with warmer color temperature. I immediately found the Western one more comforting, relaxing, while my wife (Japanese) prefers the brighter one. Internal lighting in Japan is almost uniformly overhead neon, without the baffles you'll see in many North American offices. I've grown used to it, but would rather work in the dark. I'm sure there are many people that, like you, feel that these LED bulbs are too dim. If you're at all curious though, I'd recommend that you find one and give it a shot, many of them /feel/ brighter than the numbers would lead you to expect when compared to an incandescent. It might be better to compare on the basis of Lumens, as watt's are a measure of power instead of brightness[1]. 1 - http://en.wikipedia.org/wiki/Incandescent_light_bulb http://en.wikipedia.org/wiki/Incandescent_light_bulb
- kijin 14y agoI grew up in Korea and moved to the West (USA & Canada) in my late teens. I found the lighting very annoying almost as soon as I stepped foot in my first dorm room. Even when I rented my own place later on, I could never make my living room look "proper", since none of the apartments I've lived in had any lighting fixtures in the living room. No amount of indirect lighting can compensate for the lack of several thousand lumens, daylight color, right in the middle of the ceiling. I can see why other people find 2700K 60W "relaxing", but to me it feels like perpetual twilight, some sort of reenactment of Rembrandt's paintings. Ditto for "desk lamps" that can't evenly illuminate two Letter-sized sheets of paper side by side (the typical dimensions of an open textbook), let alone the whole desk. To this day I still don't understand why students buy those. Maybe they just put them on their bedside tables in case they need to find their way to the bathroom at night. On the other hand, everyone's computer screen is too bright for me. My screens are usually set to 25%-40% brightness unless I'm using it outside on a sunny day. So I suppose people do have varying tastes about illumination.
- tomkinstinch 14y agoI got my parents a Switch[1] bulb for Christmas. If the Cree bulb is anything like it, I'll be swapping out the CFLs I use the most right away--$13 at Home Depot is better than the ~$45 I paid for the Switch. It puts out great light and "feels" better than a CFL bulb. Not sure if it's the ballast frequency, color temp, or the spiky emission spectrum, but CFLs bother me. 1. http://switchlightingco.com/ http://switchlightingco.com/
- joshuaheard 14y agoA light bulb is the biggest thing since the light bulb? The light bulb was the greatest invention of the 20th century, but the story is about to an energy saving light bulb sold at Home Depot?
- ptaipale 14y agoThe light bulb was invented in the 19th century. A patent was granted for an incandescent lamp in England in 1841 but the first commercially viable design was by Edison in 1879. I think the story itself, however, is a demonstration of an extremely annoying web site design.
- joshuaheard 14y agoThe light bulb was invented in the 19th century, but did not become important until a massive electricity infrastructure was built in the 20th century. If the joke was about the horrific web design (and it was horrific), I didn't get it.
- ptaipale 14y ago"Important" is a relative matter of course, and surely light bulbs were not as ubiquitous in 19th century as they were later, but e.g. London had 2.5 million light bulbs at the end of 19th century. That is not insignificant.
- Avitas 14y agoI like the Philips L-Prize 10W 900L better. It's $15 when it's on sale.
- rosser 14y agoI can't find any information on the CRI (color rendering index) of these particular bulbs, but Cree was making a bulb a couple years ago that was rated over 90, which is generally considered excellent. If these are comparable, they're a fantastic deal, particularly given the warranty.
- ars 14y agoCRI is 80: http://www.homedepot.com/catalog/pdfImages/36/36f3e188-bdb8-40ac-a7ad-ef9ae6c129b6.pdf http://www.homedepot.com/catalog/pdfImages/36/36f3e188-bdb8-... which is slightly worse than most CFLs. Note that 80 is the minimum legal to qualify for Energy Star.
- msutherl 14y agoThat's a deal-breaker. Don't buy this bulb. It will make everything look awful.
- lusr 14y ago"CRI is not a good indicator for use in visual assessment, especially for sources below 5000 kelvin (K)." Bulbs in question are 2700K and 5000K. Does your conclusion still hold? [1] http://en.wikipedia.org/wiki/Color_rendering_index http://en.wikipedia.org/wiki/Color_rendering_index
- thisone 14y ago2700k isn't bad, but 5000k? That's grow light spectrum. I've seen people complain over the "too whiteness" of 3000k bulbs never mind 5000k.
- bemmu 14y agoThese are probably available everywhere, but since moving to Japan I found some motion-detecting LED light bulbs. Now when coming home or walking down the hall at night the light turns on automagically. Saves both time and energy.
- FoeNyx 14y agoYou said "at night", so it's not only motion-detecting but also comes with a light sensor to avoid to turn on in bright day light, isn't it ? Do you have an URL or a name to provide ?
- galaktor 14y agoWow, that "auto-aligning" of the (supposed) current slide to my screen is incredibly annoying.
- quorn3000 14y agoI'm amazed when this kind of usability is rolled out. If they'd just asked 5 people for feedback.
- jckt 14y agoTalking just about the incandescent ("classic") light bulb's life...isn't its life limited by the policy of "planned obsolescence"? http://en.wikipedia.org/wiki/Planned_obsolescence http://en.wikipedia.org/wiki/Planned_obsolescence Are there any lightbulb engineers on HN that can confirm that lightbulbs are indeed, so to speak, "made to fail"? Or is it actually really difficult to make a long-lasting lightbulb?
- sbierwagen 14y agoIt's .046mm tungsten wire that's heated hot enough to glow white. You try and make it durable. You can buy "rough service" light bulbs: http://www.bulborama.com/Turbo-Life-20-000-Hour-Light-Bulbs-c34/ http://www.bulborama.com/Turbo-Life-20-000-Hour-Light-Bulbs-... They are, of course, much more expensive per-unit.
- ars 14y agoSee what I wrote here: http://news.ycombinator.com/item?id=5329833 http://news.ycombinator.com/item?id=5329833 You can pick any longevity you like - it's a straight tradeoff of energy efficiency.
- davedx 14y agoI can only buy these from Home Depot in America?
- L0j1k 14y agoWhoever made this site is an idiot.
- paulocal 14y agohow about the standard spotlight sized ones?
- kayoone 14y agoThis might be obvious, but its not that this is something new. Lightbulb makers want to sell lightbulbs to you forever, so they wont give you ones that will never need to be replaced!
- swagatata 14y agoThis is another cool light bulb : http://lifx.co/ http://lifx.co/
- jwr 14y agoWe are still in the dark ages, though. Just consider: this "bulb" has to plug into the standard 110/230V AC electrical sockets. Powering an LED is nothing like powering an incandescent bulb: you need a constant current driver delivering a precisely measured DC current that, depending on the LED, is between 300mA and (say) 1.5A. The voltage you need depends on the number of LEDs in series, but assume 3.2V per LED. If you want dimming, you need to do PWM (pulse-width modulation). This means that inside every "bulb" like this there is a small switching power supply. And small switching power supplies that can take you from 110/230V AC to 3-24V DC are a) expensive, b) not very efficient. Even more amusing is the "dimmable" bulb: traditional dimmers in AC circuits use triacs to effectively cut out (e.g. cut to zero) a part of the sinusoidal AC waveform. Meaning you get a chopped-up sine waveform behind the dimmer. Any switching PSU won't really notice, as long as there is enough (let's use a technical term) "oomph" left in the waveform. So, what the "dimmable" solutions do, is look at the AC waveform coming in, notice that it isn't really a sine and a part of it has been cut out, estimate how much has been cut out, and provide a PWM dimming signal to the LED driver. Sure, it's all still better than the incandescent bulb, but it's very costly and inefficient. It also generates a lot of waste: if you throw out an incandescent bulb, it's really just some glass and a little metal. The LED "bulb" contains at least 20 electronic components and a PCB apart from the LED itself. I think that sooner or later we will need an additional electrical standard, 24 or 48V DC with an overlaid control signal for dimming and a new standard for sockets. 110/230V simply doesn't make sense for powering single bulbs anymore.
- tehwalrus 14y agoI agree that we need a closed-circuit DC solution for households. One efficient step-down, and then we plug rechargeable (phones, laptops, etc) in, and power LED lights off it. We still need AC to transmit power to the house, and power high-juice devices, obviously. Presumably this already exists? Any home-hackers know who's making them?
- cincinnatus 14y agoThe off-the-grid folks are surely on top of this. They also have the advantage of a 'natively' DC supply coming off storage batteries.
- kephra 14y agoThe comparison is shit, because it compares shit (LED) with shit (fluorescent). The website does not tell if Cree is using two band LEDs of a blue LED with yellow dotation, or a 3 band UV LEDs with R, G, and B dotations. Its likely only two band, because those are much cheaper. So they are worse than any 5 band fluorescent lamp. And not comparable in light quality with a good old light bulb or tungsten halogen lamp. They are not suited for sewing, when you need to match the color of the thread to the cloth, and they are badly suited for electronics, when you need to read the color code of a resistor.
- NatW 14y agoCree LEDs (not just bulbs) are sold to 3rd parties, too - and I've seen them used a bit on various Kickstarter projects. e.g: this one: http://www.kickstarter.com/projects/1324892969/open-source-ultra-bright-led-light-pad-with-wifi-a http://www.kickstarter.com/projects/1324892969/open-source-u... A standard 100 Watt lightbulb gets about 16 lumens/watt. The 9.5 Watt lightbulb here can get ~ 84 lumens/watt. The 9 Watt (more blue) lightbulb gets almost 89 lumens/watt The above project can get about 90 lumens/watt. .. but higher efficiencies and cooler temperatures are possible .. e.g: this one spaces out the LEDs and claims to get 133 lumens/watt: - I don't know if they are from CREE or from a competitor: http://www.kickstarter.com/projects/619878070/nanolight-the-worlds-most-energy-efficient-lightbu?ref=live http://www.kickstarter.com/projects/619878070/nanolight-the-... Higher efficiencies are coming from Cree and others in the future - so it's going to get better. In the lab they're sometimes getting even in the realm of 200 lumens/watt.
- buro9 14y agoGreat. Except for those outdoor pictures at the bottom, because all I see is a massive amount of light pollution. Does a Burger King really need to be lit like that? No-one is there, perhaps the lights should dim dramatically and sensors should make them come on depending on movement. For indoors these bulbs are great, but for outdoors I care more about the excessive light pollution than the power usage.
- dutchbrit 14y agoI'm not a huge fan of Cree's heat sink design - I prefer the Pharox bulb personally when it comes to esthetics, http://www.solarengineeringltd.com/renewableenergy/images/Brands/Pharox/pharox_200_p45.jpeg http://www.solarengineeringltd.com/renewableenergy/images/Br... However, we aren't buying a car here. Nice that Cree's 60 watt replacement which actually produces 800 lumens, compared to other bulbs that claim to replace 60 watt lightbulbs that actually produce 400 lumens. Amazing that they managed to produce that amount of lumens with such little amount of energy - has anyone tested this bulb here? Also, very affordable compared to most manufacturers!! Disclaimer - I use to work for Pharox. They were leading for a while but seem to have been overtaken.
- davidkatz 14y ago"the biggest thing since the light bulb". Keep reading their marketing, and you get "it's a bulb that lasts longer than a normal light bulb, and consumes less energy". So let me get this straight — the light bulb took us from expensive, unreliable, dangerous light (candles) to instant, cheap, reliable, safe light. The light bulb is one of the greatest inventions of humanity. You made it a little more efficient, and you invented the biggest thing since the light bulb? Gotcha.
- hmsimha 14y ago-How many HN readers does it take to change the light bulb?- 6 to discuss the efficiency of the new light bulb, 10 to propose alternative designs to the light bulb components, 15 to point out various health and environmental concerns of old and proposed new light bulb components, and 25 to criticize the design of the webpage promoting the new light bulb.

- h4pless 14y agoSo quick question... I noticed that when this site was posted to Facebook, FB rendered the title of the link as "New Site" above the URL instead of "Cree LED Bulb" but I am not seeing anything in the metadata that should cause this. What am I missing here?
- Amarandei 14y agoThat's nice and all, but a 60 Watt bulb is still not bright enough for my taste. I have never used old 60W bulbs exactly for this reason. I always feel like I'm struggling to see things with those bulbs.
