They are screwed onto the heat sink surface. My friend is going to add a 2" aluminum "shield" around the entire unit to block off the light so someone looking at the tank or walking by won't see the LEDs.

(more numbers to get lost in) Each emitter has a 100 degree spread which is perfect. 13 emitters per 5'8" heatsink and it's 12" wide, 2" tall. It's literally only 3.5" from the water surface, with good shimmer, full spread and no "spot lighting" or "disco ball effect". The two fans blow air up on the right side but most of the cooling is my conduction/convection. With all the lights on, there were still sections of the heatsinks that were cool to the touch and at most it was barely warm in parts. My friend will be adding pieces of aluminum on the open ends of the rectangular tubes which will make the fans more effective.

I can literally pick up the lighting unit with one or two fingers.
