I modified a few more Mars 300's
Order the heat sinks from heatsink USA
I used Cree COB's CXB 3590's in 3500 k 72 volt.
I used Arctic silver 5 thermal paste.
I also used kapton tape.
Pretty easy mod just take out the old board and heatsink and secure the two new ones silicone them in and drill a hole and put your wired thru. I used the existing wires from the unit.
Here they are waiting for solder
I also was able to securely attach reflectors using kapton tape here it is.. This is my third unit I have ordered 4 more reflectors for the above new units.
