I'm thinking of buying some warm white cfls for flowering, i know the spectrum (2700k) im thinking of getting the 42 watt ones as well as maybe one of the 200w ones, but my question is on the 42 watt ones the lumens are only 1600, but i bought a Daylight spectrum bulb from a grow store and it had 2,600 - but they didnt carry warm white spectrum. Should I go ahead and buy the one with 1600 lumens?
