If you used a single 4x ballast, then you are getting slightly less than 108w(related to my previous comment about ballast factor being different depending on whether all the leads are connected for not), I say between 100w and 108w, actually might even be a bit less than 100w. Of course, you can easily get more light by adding another ballast if you want.

when I have some time, I will do the actual measurement for you. I have 2 T8 tubes, just need to hook up another pair of endcaps.

Truvu 100g Flourite, wet/dry, AHSupply 302w PC, PinPoint controller
10gallon15w T6+15w T8
55gallon40w T6 ODNO4x, no CO2. Discus grow out.
10gallon Tonina tank, 2x15w T6 ODNO 4x
I will do aquascapes after I collect all the plant species and grow them to perfection.
