DIY LED's

[widebody]

i have 2 used heat sinks if you want 12" x8.5" with acrylic shield and some old expoy

Any feedback on heat sinks? If I get 2 16" x 8.5" heat sinks I can do 3 rows of 8 led's spaced 2" apart or should I do 4 rows of 6 led's?

He has a aluminum sheet, it's not a heat sink but will absorb the heat. I was told a aluminum sheet will be enough but I like the look of heat sinks
