Review on YGS-Tech 2 Inch LED Recessed Lighting Dimmable Downlight Industrial Electrical by Bruce Marable

The supplied 120V connectors are required for connection to the building wiring in the junction box in accordance with electrical codes. I used lamps powered by a 12V DC transformer. A junction box is not required for low-voltage connections. So I just unplugged the 120V to 12V driver (small plastic box). They work great and are fully dimmable with my 12v dimmer. Two cons: These spotlights get hot! I tested them at 135 degrees Fahrenheit at full power. (too hot to touch) I would not use them in confined spaces or in contact with insulation. My research shows that anything below 195 degrees Fahrenheit can come into contact with drywall. Second, I ordered a second set of 4 warm white bulbs and the color is significantly different from the first 4 warm white bulbs I ordered.
