I like the 2700k color temperature. Color rendering CRI is 90+ as stated. I hate when people ignore CRI and end up with ugly LEDs that don't show true color. They also have good flicker free power supplies. A circuit in my house that the power supply made was causing an audible hum through my stereo. To fix this, make sure all audio equipment is on one side of the 120V and you can fit switches for the lights on the other side. Or use ground loop isolators. Higher quality power supplies will not generate signal noise on power lines. The lights don't hum.
