I brought in another reflector that may fit, the big fixtures will only draw 4 amps if there is a 400 watt bulb in there (which iirc only 1 has), if all fixtures had their proper bulbs I think it would be plenty bright, perhaps supplementing would be sufficient for the immediate future. Also, it has the advantage of not needing at least 16 of those CFLs you mention for similar lumen output. MHs are decently efficient, far more than old florescent, and a T5 setup would be great that would be the better bulb, but the $1k needed I think has more immediate need elsewhere. Can we revisit it after seeing how they look when there all bulbed and running?
Also, when are we getting bulbs for those?
