These bulbs perform better than many other well-known brands I've tested including Philips (Homedepot) and Feit (Costco). It's a beautiful white daylight, in contrast to the bluish tint of previous LED bulbs. A simple way to check for flicker is to record a video in slow motion (240 fps). If you see flickering (or flickering) during playback, then this lamp has an unacceptable flicker level. All LEDs must not flicker when supplied with a good constant current. But the underdesigned AC and DC circuits in LED light bulbs cannot properly convert 60 Hz household AC power to smooth, ripple-free DC power. Much better than the Philips bulb. I paid $35 for a lightbulb as an early adopter.
