I swear by the Spectra lights, ofc that is also because its the only led i have experience and further i havent even completed a cycle with it. I have used it as side lighting and for veg cycle (id did great) and i am 5 weeks in on flower with it alone, but so far i have not seen the results (yet to finish). I would definently go with the Spectra from Growledhydro (.com)
They are right, the site does look like crap, and is more than a little confusing considering the old and new products in the same descriptions. Your best bet would be to contact Mike and ask him what kind of deal he will give ya if you have 1k to spend. Chances are he will cut you a fantastic deal (even i got one on a small single unit). Its worth an email.
I have seen results from the Blackstar leds, and they do indeed look good for the money, but as i've said before i just dont like the company. I do hear good things about the Diamond series, but havent taken too much interest in all these newish companies.
