eye blue, huh? are those special in some way? i just bought a cheap 39k lumens (i think) halide with my light system and it produces a pretty even spectrum white for it's above average output, but specs can be deceiving. i'll have to look the eye blues up. if some breeder makes a point of preferring those, there must be a reason.
looking those up ought to break up some boredom and monotony for a minute.
OK, so they're full spectrum and replicate sunlight, but are only rated for 29,000 lumens in a 400w. the C.A.P. maxlume is rated 39,000 lumens. i think that's what i have as i bought it because it was cheap and had a high output.
i'd like to see the two bulbs side by side. it could be that the cheap unit used a different measuring system to artificially boost it's output over it's 29-34k expensive competition.
