Review on Efficient Recessed Downlight Installation: Sunco Lighting Industrial Electrical Components for Lighting by Paulo Heisler

I bought these specifically to replace a contractor's dimmable LEDs which flicker quite heavily. Boy am I glad I installed 2 to test first. The best way I've found is to record super slow motion videos with your room phone and lights. At full brightness, they flicker just like our current lamps. The luminous flux on them dims very quickly, giving a smaller useful dimming range. When dimmed, they flicker a little less than our current lights, but still flicker. They return.
