need an experts opinion

in the pross of converting my box into a more stealthy box, i dont have pictures but i have measurments, h25 inch,w7.5inche,deep14.5inch

with those measurements what can i expect?

i currently have 6 26w cfls in the box with about 15-17inches of hieght left

42 pounds would be my guess

Hmm, you may want to make the area smaller as your yield will disrupt the gravitational pull of the earth and could affest tidal patterns, natural disasters, etc.
