Lunar Simulator Size for a 75g?

[kayl]

I am upgrading to a standard 4' 75g tank - I presume the 2 LED version of the Lunar Simulator will be sufficient, but wanted to get input from someone who has the lights already...

Will 2 leds be enough or should I go for 3 or 4?

I'd go 3 or 4. Maybe 4 would be a bit overkill though. I am running two lunar sims with 5 LED's each on my tank and feel I could use a bit more but my tank also has a footprint of 4'x8'.

Agree. The suggestion is 1 LED per 2 feet of surface; I always add 1 more just for a little bit extra.
