Review on E-Star Series Slim LED Recessed Lighting 8 Inch - TORCHSTAR Industrial Electrical, Featuring Convenient J-Box by Andre Belitz

They are elegant, bright, have no lag at 100% on, fade smoothly across the range, and look premium. they will hum something. Even at 99% or 1% they hum. I checked 3/6 of the ECUs and they all buzzed about the same. The sound is about as loud as that of a large fly and can be heard up to 15 feet away outdoors. .The noise comes from the electronics box, so theoretically you could put some insulation around it to muffle it. However, I don't want to imagine how 6 of these will sound behind drywall. The dimmer used is a standard triac. Dimmer (TP-Link Kasa HS220). These dimmers didn't buzz when dimming about 8 other brand LED bulbs so I'm pretty sure it's not a dimmer. I really like this design/brand but I will only buy bulbs that don't need to be dimmed. "Basic" version - same size, same design. The differences are a lot less hum, a little brighter, dimming to a lower level, nuts instead of clamps.
