If his are like mine it can be more like minutes. You get some immediate light and then over the next minute or two it gets to full brightness. This is probably due to cheap bulbs or what not but it can be annoying.
I even have a problem with CFLs in a different room where on occasion I turn the switch on and the light won't come on at all right away unless the other switch that controls a different set of lights is on already. It's pretty bizarre. It's not a big enough deal to spend the money on finding an electrician for something this small but it is strange.
- ars 13y agoIf your CFLs take too long then get some new ones. Walmart ones are great. All of mine turn on instantly - if they are not technically at full brightness I certainly can't tell. Except for those from Feit Electric - those are terrible, don't buy from that company.
- umsm 13y agoYou may have electrical problems (or any number of other problems) that may effect your judgement of CFLs. I was just saying: An "instant" on and off light will affect your vision differently than one that (for example) dims slowly for a few seconds after turning it off. If this isn't "by design" and it takes minutes, than that's a serious problem.
- No1 13y agoAvoid the amalgam CFLs - they get more on/off cycles before they go kaput, but are allowed up to 3 minutes to reach full output and still get an energy star rating. The rest of the energy star rated CFLs are supposed to reach full output within a minute.
