This may give you an idea of the problem. This one is for five 3 watt LEDs and it's a foot long.

But remember the size of the fixture is 7 1/2" by 5 1/2"

If you can make this one fit and you run them at 200 ma. you should be home free.

If the heatsink isnt forced cooled then a dose of black spray paint will improve its effciency a little, dont forget too that if you put the 'sink in an enclosure with no free air you wont get the manufacts spec from it.
