I was thinking about these blue LED's- LUXEON V High Brightness LEDs

And these red LED's-
LUXEON III LEDs

Just 1 of each would make approx-200lm. Thats alot of light. Now say I had 100 of these LED's. That sould be more than plenty.
However my 1200+ LED array only takes up 12"x12" so putting 5 of these puppis in would make alot of light also. On average the array will make approx 6000cd of light, not mcd, cd. so I am having trouble picking between the two types, 5 mm or class 2 LED's.
