Lighting Modified Mars hydro

[Ripper]

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.

Where did you get the reflectors? I got 2 of the cobs and may get 2 more? Thats a nice job bud!

Thanks man! Maybe the cobs will still be on sale. Are they 120 or 90 deg reflectors

They are the 90 degree LEDil white plastic 90 degree .. I have seen them tested by growmau5 and they are the good ones.

Anytime it is a pretty easy conversion. Let me know if you need any help.. I got the COB's for $36.00 each
