CFL grow box, helppp

Hi,made this owta a old door loll, the CFL at the top is 250w
the other 3 are 20w. the problem is that the smaller CFL's are touching the plants, and i can't help this, so i was wondering would it be acceptable to maybe put something around the lights to stop direct touch with the plants, i was thinking of something like cutting up a clear plastic bottle and putting this round or would doing this reduce the lumens reaching the plants?????
Cheers, Matt.
(P.S. the plants are skunk 1 and are just over a week into flowering.)

any one?

what R ur temps in the there. looks like U need a fan.

naa temps are ok, its in a shed outside lol i jw bout the lights as i cant stop them touching the plants.

hi , the lumens would be reduced but by how much. who knows. u would be better of making the side lights adjustable n move when ness.

ok then thanks, ill try and do make them movable
cheers
