Ken,that site didn't have a lot of information.This documentation on Ebay desribes them as constant voltage, constant current driverssuitable for high power LEDs. LED Power Driver Constant Voltage Current Adjust CC CV

It does say to heat sink it if running more than 25W. Heatsink version available on his site. When I mentioned the price to my LED friend yesterdayhe was a bit dubious & suggested I might get what I payed for.You have prompted me to do a bit more experimentation; so have it running at the momentdriving a 60W LED & will see how long it runs for.Hope you enjoyed the trip to Ireland.Alan

Subject: [PSUBS-MAILIST] LED Driver  Bought this LED driver & a 4000 & 6000 lumen emitter.It may be helpful with regard to our open source light.This one describes itself as having a wattage output limitation, beyond which cooling is required. This may be just a heat sink butI'm not sure. There are other higher powered constant voltage, constantcurrent drivers on site. There was no description of how it worked with the product, but managed tofind one on the site posted at the bottom. The blue trim-pot on the leftincreases voltage by a clockwise turning & the right trim-pot increases current.AlanLED Power Driver Constant Voltage / Current Adjustable Module - Blue + Black
