Hi Guys:
Maybe this will help.
I failed algebra so I'm not even going to try to figure this out.
I went back to the lighting store & held the light meter 1' under the center of the bulb, ( should have done this the 1st time, the sales guy's getting tired of me bugging him), & the lumens were only 6,100 not the advertised 8,900. It still seems like the lumens at 2 1/2" should be alot higher but I checked it again & got the same readings. By the way the meter he used has a digital read-out. He said they cost about $500.00. So I figure it must be a pretty accurate meter.
This doesn't mean the EnviroLights suck or anything, & it doesn't mean I'm going to go trade my lights in on another 430w hps, actually it really doesn't mean $hit. What's really going to matter is the dry bud weight. Remember, I think I'm the only one here who has already used the EVLs for a complete grow, and not under the best of conditions. I got 5.5 oz. from one 33"tall plant.
Like I said before I really don't know jack about all of this scientificaly, I just like the way the lights work for the size of my grow cabinet.
Later Grow Bros.
