Solid product
Works for my 100 watt led. The adjustment screws let you dial in volts and current. In testing is did not get hot at all

Poor fit
I just got these and followed the directions in the auction pics and it’s not a good fit. They just seem to have picked the wrong sized o-ring but there is nothing for it to hold in place except shallow threads meant for regular ceramic heads. Don’t waste your money.
