Lumen output for warm-light fluorescents
I'm building a lighted stand for my Nepenthes and my soon-to-land orchid hobby ('cuz I TOTALLY need another hobby). In researching lighting, I've noted that the lumen output for the warmer-spectrum fluorescent bulbs, lower K-values, have significantly diminished lumen output per bulb. For example a 4' T5 in "cool white" has about 5000 lumens. The same bulb in "natural" or "warm white" pushes about 2600! I like to incorporate some warm lamps for visual effect, but my previous setups were regular ole T5 or T8s and my plants then didn't really need the HO lighting.
Now these are bulbs at BLowes and Home Despot. I haven't tried the Trustafarians at the grow store yet... while sometimes they're very well-informed, sometimes they aren't. At the top of their voice. And if you're growing something legal, I find they are even less well-informed .
BUT: is this universal for fluoros, just a trade-off for the change in spectrum? And for the nerd in me, anyone know why if that is the case?
