Some one answer this question, because I have found that 75wt hps, lamps are much cheaper, plus you have no ballast to deal with, cause you can get them internal!

Lumens and number of lights For a fairly small grow cab situation (no bigger floor area than 2' x 3', or possibly 2.5' x 2.5'), I was debating which would be the best use of light, considering... - I don't want a lot of noise - I want to use as little power as possible - I have no immediate plans for C02 enrichment. As such, I'd like the lights to give adequate light per square foot, but not generate unnecessary heat (necessitating further climate control measures, hence more noise and more power consumption.)
