This kit was much easier, it came with stick on thermal pads enstead of glue or grease. It was also drilled and tapped. I've got 6 unused slots so I could get crazy and add some cyan or other colors to mess with. Important tip, don't try to tin your LEDs when the are attached to the heatsink, they don't heat up and it doesn't work. I had to take them all off. Kind of a pain.(flame)
