Well, I measured lately some lux....
At 14.00 h outside in the sun ( garden ) I measured 71000 lux
At my tank 2 inch under the pendant I measured 69000 lux
So : a lott..
6 x 54 Watt T5 bulbs with special reflectors and cooled with fans on the cold spot to gain an extra 20% light.
Makes total of 324 Watt.
If I translate it to "normal standards, I would say 5 - 6 W/G
