Lighting

[woyeng**]

I read that lighting for tank is measured roughly based on 3W per gallon of water. Is the 3W derived from the total power capacity of the Lightset ? Example, maxspect G2 170W has a total power output of 170W so based on the rough guidelines, can support up to a 56gallon tank.

Hope to gain some insight into this ...

based on what i have been reading is that is true for high range led system. but for t5 and mh i think will need higher somewhere in the range of 6-8wpg
