i think around 250 or 260 CFLs would be a few to many...CFLs are weak so i wouldent worry about over kill on 4 clones..unles you have like 10 or 12 extra sockets laying around..then id think twice but the plant they came from...how many lights was it used to? if it looks like to many lights then it probably is...then all you do is move the CFLs a bit further away and its like they are almost gone, problem solved...

ok dude please do not take my answer very seriously. i just have a grudge with CFLs. i can never seem to have enough...i want a small portion of the sun in my closet. then i will be happy...i will share, you can have a piece for your clones.
