Here is my worry...it seems like every grow or review on the Magnums are by someone tied to magnum. The "dunit" dude I don't think is tied to Magnum but his grow is featured on the Magnum youtube account.
I haven't seen anything bad or heard any horror stories about the mag. The only thing bad I heard is from Avant2000 who JUST joined and only posts are talking about Magnums bad build and a bump for California Light Works, yet has no sign of owning one.
Now with that said, and not having anything really bad out there about magnum, the fact that they have that ledbudguy forum and people who act as reps posing as normal folks, it makes them seem suspect.
So, even though I really think the mag is legit, I'm not 100% sure. I'm tired of these LED companies being all shady. I talked with a rep from Optogan, who has been a leading innovator in LEDs (not for horticulture), and asked if they ever considered making horticulture lights and they are in the works but nothing yet. God I hope so because they are reputable. Lumigrow and TI SmartLamp seem to be the only to super legit horticulture lights but damn they are like $2000+ for just 300w.
I'm trying to find as much as I can on the AdvancedLED Extreme Flower lights. While I can't find anything bad, I'm not really finding anything good either. They are a US based company and ship out of their US warehouse, and claim to use Cree and US made Bridgelux.
I see everyone talking about Blackstar but something tells me those things aren't built to last. I'm a firm believer of "you get what you paid for" and the fact that they don't put real power draw on their site immediately turns me off to them.
So far, for what is affordable, Advanced may be the way possibly. Still hunting down stories. Pro Grow seemed hopeful until I found their horror stories. Like I said, Magnum doesn't seem to have horror stories but their "secret agents" running around makes me weary of them.
So unless I find anything bad about AdvancedLED (horror stories of dishonest business, lying) then I will probably get the 360w Extreme, if I do find something, then I will pull the trigger on the Magnum and cross my fingers.
