Hi All,

So finally i received the drivers... Well almost, just have to pick them up from the post office.
Im finding myself in a bit of a dilemma. I plan on mounting the cobs using molex holders but my drill decides that it doesnt want to work anymore so drilling and tapping is going to be an issue. I will have access to a drill tap in a month or so but i can wait that long to get them up and running.
My next option is to use adhesive thermal pads and solder the leds but im not a fan of soldering and dont want to go this route and risk damaging the cob surface.
So while on the meds i came up with a plan, just need to know from the experts if it would work out or should i just wait for the drill press....
I will fit the cobs to the molex holders and then mount them to the heatsinks using thermal grease and kapton tape...? Would this work?

Do you have some leftover led or cfl bulbs / equipment to easily mount them in a PC case?
You could already start vegging then, PC case is I guess 1 square foot max, 30 (real, not equiv)) watt of LED bulbs should veg it very well.

I'd wait for the drill press, not really a big fan of soldering / adhesive pads either.

@frica I currently have a grow going on in another case using cfls 3 x 24w 6500k
Being my first grow that will make it to harvest, its not really the best which is why i didnt post it up here.
These new LEDs will go into another PC (1.5sq ft) that i have lying around which is why im so anxious to get them up and running.
I guess i will have to just wait for the drill press... Thanks for the reply

I soldered mine, and used thermal adhesive to mount them directly to the heatsink. Only downside is that they are permanently on the heatsink.

As long as you put solder on the contacts before you mount the cobs on the heatsink, soldering the wires to the contacts is easy. For me keeping a steady hand is the hardest part.

The real problem is that the plants can absorb lead, which you really don't want in your smokes.

Quick question.
So using the cree product tool, it says that @600mA the CXA2530 will require 36.4v
Can i get away with a driver that outputs 36v ???
