You can buy good LED drivers with up to around 20kHZ PWM, but even 800 hz is enough to not see the flicker anymore, though it will show up on a video camera as stripes. It's the cheap 250 hz drivers that are painful to the eyes.
- spython 4y agoHere's an example for a controller going up to 16 kHZ. http://www.iskydance.com/index.php?c=product_show&a=index&id=1644 http://www.iskydance.com/index.php?c=product_show&a=index&id... (no affiliation). Would need a DMX fader to control it though.
- rahimnathwani 4y agoCan I buy wifi-enabled bulbs that use these? I use TP-link Kasa color-changing bulbs (although I'd be happy with any that can change colour temperature between daylight and candlelight), and the flicker sometimes bothers me.
