This is going to be free-air mounted with a 12-watt 80 CFM ball bearing fan mounted against the side of the heat sink. Silver Oxide heat sink compound. Mechanically attached chips. Twelve of them. 120 watts of these chips put a 150 watt Metal Halide (Hubbell) lamp to shame. But that's not the idea. The idea is this is for 12 volt operation, without inverter. Theft resistant. Our little uñados will spent a whole night digging out an inverter. The battery box is steel welded to a 4" diameter steel post (lamp) sunk deep in the ground. No room in the box for an inverter. Designed to light up a beach at night (where RV'ers Park).
