Have seen little about the effectiveness of the Wonderlights with
orchids. Have also seen claim they are short-lived. Anyone have
success with such bulbs? Do they we require a special socket or can a
standard bulb socket work? Have a 4x4 area with phals that needs more
lumens! Metal halide I am afraid would heat my small apartment.


Merrill,

MH light would give you less total heat than the equivalent number of
fluorescent fixtures. For supplemental light you could get a 250 or
200W MH light. Sure it gives off a little heat, but if I could figure
out a way to make light without heat, I'd be famous (and no doubt
imprisoned for fraud). MH lights aren't really that effective at space
heating.
