hey all, need opinions on my setup

BOX PAREMETERS
Width: 10inches
Length: 20inches
Height: 20.5inches

im doing a SCROG grow.

i have a rig of 4 compact flouro bulbs wired into a mechanical system, all hung from the lid of the grow box.

the lumen output of each bulb is 2900 and they are 45 watts each. very very bright.

so i have 4 currently, @ 11,600 total lumens. If i do this on a scrog grow in a grow box, will i yield enough? i want to use these for the entire grow.

I may rig 2 more of the same bulbs into the rig and get a total lumen output of 17,400. I did some research and thats more than some 150 watt hps systems.

i do not want to use HPS or MH because of the heat out put, this is a secret grow and i want to be incogneeto about it.

will i yeild a good harvest with 17,400 lumens on 2-4 plants using SCROG?

PS.
is this equation correct?
Square Feet: 1.38'

@ 11,600 Lumens
Footcandles (fc) = 8405 Lumens per square foot.

@ 17,800 Lumens
Footcandles (fc) = 12,898 Lumens per square foot.
