Yeah, I think my Ikea ones are phosphor, the Philips Hue are RGB though and still fine.

Anyone know what the LiFX bulbs use? We have a dozen of them and the adjustable color temp is great. I also have a box of smaller LED bulbs from Home Depot. Neither hurt my eyes and I don't (didn't, will see now that I'm paying attention) notice a difference, but I'm sure there is one. I also wonder about e.g. The Anker desk lamps, where the bulb is built in. I have one behind my monitor with the head turned round (it's designed to do this) to throw light up the wall behind my monitor as bias lighting, and another (their clamp lamp) on my electronics desk. They're great lamps with annoying touch power buttons, but both are adjustable color temp and have built-in LEDs which never require changing.

  LiFX let you set the color right? So by definition they're going to be RGB (have three colored LEDs inside). Generally, LEDs that are single color are more likely to be phosphor (blue LED inside with a phosphor that converts to yellow).

I went to LEDs in my apartment about two years ago. 3 Hue bulbs + hub, some 48" T8 LEDs, and some E26 Ikea bulbs. The Ikea bulbs are great, power on instantly and slowly fade off. The T8s take about 3/4 second to turn on, and are nice and bright (and a far cry from the power consumption of the T12 florescent bulbs they replaced). The Hue bulbs... well, one's developed a noisy transformer. Replacements are, what, $40? Meh. I like the Zigbee integration, but not $40 in two years worth of like. And the CRI of the Hue is just as bad (actually worse) than the other bulbs. Lesson learned, those Ikea bulbs are great.

  Not trying to sell Hue here, but their bulbs have gone through several iterations by now. They were one of the first big names to push consumer LED bulbs, I wouldn't be surprised if their earlier versions had flaws just by being new. But maybe not, I don't know. (Also their color bulbs are $40, but they have much cheaper white ones, and also an in-between model they call ambiance which are white but allow you to adjust color temperature)

Yes, you can tell the Ikea ones aren't flickery because they have huge phosphor persistence - several seconds after being turned off.
