A. Trim LED stars to fit inside enclosure.

B. Position stars on back bezel with an extra piece of L-bracket which is same thickness as Hammond enclosure.

C. Rotate center star 180-degrees so the + and - tabs are next to each other on adjoining stars.

D. Glue stars with Arctic Silver thermal adhesive, then clamp until cured (five minutes).

The arctic silver thermal adhesive can be found on any computer supply website. www.xoxide.com for example. Just remember to get the adhesive and not the "paste" which is just for heat transfer properties that might be disassembled later.

Does it matter which way up the LED's go as long as the middle one is the opposite as the others?

[spaghettikid]

For the arctic silver adhesive which glue is it exactly because they have arctic silver of several types, arctic alumina of several types, the arctic alumina is much cheaper but will it still work?

I used the premium arctic silver from LED Supply. Any good thermal adhesive should work or contact them for recommendations.

Cant the back of the led short out on the metal ?

Not really. It is a ground/heatsink.
