from A lot of light in a user-configurable packageI needed this exact configuration - lots of "bright white" output, smallish footprint and an external circuitry requirement. The premise is simple. The light could not interfere with a sensitive RF receiver system inches away on a test bench. Using two of them wired in series, I achieved desired results with a self-designed, constant current regulator set to deliver 19.1V at 1.04A to two series-wired LEDs. I purchased a Hammond DieCast enclosure and put the toroid transformer, rectifier and regulation components, then attached the LED's heatsinks to the lid. Two studs protrude through the bottom and mount to a bracket on my desk.Granted, it's not the most efficient method of powering these LEDs, but it is the most electrically quiet for my purposes.

from Wow, unbelievable brightnessWow, unbelievable brightness. It lights up the backyard.They weren’t kidding when they say; don’t look directly into the LED when powered on.I know, what I’m I stupid or what, lol.The heatsink gets pretty hot. I reapplied new and more thermo compound under the LED.I would suggest a fan to cool, so I placed a very small 1½ inch 12volt/0.6w fan under. I measured the voltage across the LED with the fan connected, 10vdc. Not sure if the fan connected to the LED and driver module 073-054 will hinder the performance output. I don’t think so because the little amount of power the fan draws shouldn’t harm it. If my Fluke 51 is working properly, I placed the temp sensor on top of the LED to measure the temperature. The temperature was 320 degrees Fahrenheit/163 Celsius.Don’t touch the powered LED. And yes it draws 1.5 Amps at 12vdc. not sure what I'm going to do with right now. Would be great for camping.
