We have 15000 Lux at the surface of all our tanks. Two of the tanks are 100
gallon (60"x18"x20" high) and have 4 40w NO FL bulbs over them. This is
"only" 1.6 watts/gallon, at the low end of the scale, but they are high
quality watts. We can grow anything in the tanks.

The third tank is 120g (48"x24"x24") and has two 175W 5500K MH bulbs
suspended 14" over the water. We can also grow anything in this tank.

I've checked the levels at the bottom of the tanks and vaquely remember
they were in the 1000 Lux range in the bright areas.
