Are u referring to the one made by blackstar? Have any of you fine folks used this model before? I am really considering getting it. I would like some feedback first though, if possible. Thanks....

I'm not sure if anyone here has it, but as long as you stay close to the recommended coverage I'd say it would work great, I'm impressed at how much improvement over CFL I got from my blackstar

hey muddy, it may be a good idea to let people know about the difference between the veg/ clone models versus the flowering versions of the blackstars?? micro i run two blackstarsthey work great. i have only used them for photo girls, next grow autos!

is everyone using the flowering version? of the blackstars, i have heard that autos need the flowering models, and dont do well under veg/clone models i have run photoperiod plants under flowering models and they work good from beginning to end.

Out of curiousity, What makes a blackstar sooooo great? I see that it has 6 bands of light, 3w chips, cree, ect ect. Looks pretty much the same as my GrowLightPro, except
*Light spectrums GLP 7 bands vs BS 6 bands (obviously not a substantial difference)
a. GLP - 440nm, 460nm, 620nm, 660nm, 715nm (IR), 3000K (warm white), 7000K (pure white)
b. BS - 380nm, 425nm, 630nm, 660nm, 730nm, 12000K (I'd guess it has a blue/purple tint to it)
* 8 cents cheaper per watt ($279 for 240W vs $489 for 450W),
*From what I am reading the blackstar 240 puts out about 58.3 lumens per watt as opposed to GLP producing 78.8 Lumens per watt.
Not dogging on Blackstar or anyone using it, just truly curious as to whether I should consider ditching my lights for the bandwagon I see a lot of other people on.

I think it's all the performance you get for the price, and the lens angles, and 7000k isn't pure white, it has a blue tint, I have HID headlights that are 7000k

Dude, my bad, I should of known better with 7k. Blaming it on the keyboard, lol.
The lens angle, from what I found online, is 120 degrees in the Blackstar, and 90 on the GLP. But if someone was using more than 1 LED light in a smaller area, wouldn't the lens angle matter less due to having a larger core penetration area, which is what LED users are/should be after. Just my thoughts, please educate.
Also, your statement slightly contradicts what I said. I showed that you're paying less per watt using simple arithmetic, (in conjuction with the fact that you're also getting less lumen per watt), unless you are saying that value is comparable at a lower price in another "performance" category. Can you please explain? Thank you.

I'd ask Tshirtninja, he's the LED guy here, but I believe the blackstar uses 60 and 120 degree angles
