    COB spectral research microcab

    @orangesabc123 Why not smaller watt cob? Is there any efficiency difference one way or the other? Either... The Cree tool on their website will help you to find the best emitter for your needs. Go with veros and you can do it without soldering or holders...

    Testing Osram's 150w horticultural LED fixture V1= Monochromatic dream or nightmare??:)

    Looks like the hans...errr....osram light is doing what it normally does. Low power, tight nodes, a few unhappy leaves that might be missing a little white love. But all the 660...yea baby! Short fat buds for miles is my prediction

    IF you are new to LED and want help choosing what to buy, POST HERE!

    The combo looks great. Haven't been checking cob stocks...may have to break down and get a few of those 3590s. If you don't mind the higher voltage driver than the 3590 at 700ma should be good. I don't know if theres a better bin available anywhere...haven't been keeping up lately If you don't...

    DiY LEDs - How to Power Them

    Exactly... Shipping is a little high but skipping the middleman is priceless. Same with scpower. I've only received 2 drivers from them but they are high quality as far as i can tell.

    LED PAR math

    I'm glad you separated the two. I guess I do think taking par a step further a little unnecessary. At least more a last step.. It of course helps in lighting an area evenly and adequately. My response was probably more just tired of the amount of theory threads. Not enough growers.. growing...
