im debating on these 2 lights. current usa outer orbit hqi 36" to go on my 40 gallon tank. now i dont know if i should get the light with 2 x 150 watt, or if i should just go with 1 x 150 watt with 4 96 watt actinics. and this tank is in my room im thinking 2 x 150 might be overkill and maybe might fry my room with its heat. and 40 galoons isnt a lot of water and 1 x 150 watt might do the trick. anyone got any suggestions?
