    Why no red COB's?

    Nice. I'll look into this.

    Why no red COB's?

    It's just that, sourcing a PPFD meter is not like shopping on amazon. Each PPDF has their own measuring specification, some do not measure as low as 450nm, and some do not go as high as 660nm. Some don't come with spectrum filters, some don't come with attachable ppfd readers and must be hand...

    Why no red COB's?

    Yes, you are correct. We don't have a ppfd meter but it's coming in next week.

    Why no red COB's?

    We are getting a lab grade PPFD reader, it's coming in next week, it's incredibly expensive and it will run under lab conditions. I'll have the values as well as coverage area soon.

    Why no red COB's?

    The reason why company's like cree/citizen can't make red spectrum is because they have yet to find the right material to convert the red spectrum. Too bad. We have one of the best materials on earth to convert the spectrum with minimal loss. Trade secret.

    FLIP CHIP OPTO LUNA 300!!!

    You should consider our inhouse matching heatsinks, that are shorter and a little fatter. They also weight extremely light. We use an inhouse patented fin process- reduced weight and overall temperature. Our 240W heatsink is 50 dollars, our 320w heatsink is 64 dollars and our 600W heatsink is...

    DUET 2400 (LED FIXTURE) - UP TO 2400 WATTS (Flip Chip Opto)

    Hi tstick, Great suggestion. It's on par to our discussions in the company. The reason why we are selling them at a higher price, is because by Q2-3, the current product line will be replaced by a modular design with extended features, flat panel, thin, light weight, etc. We'll still be selling...

    DUET 2400 (LED FIXTURE) - UP TO 2400 WATTS (Flip Chip Opto)

    Duet 60 @ 100W Fixture most likely won't make it on the shelves. Duet 100 @ 100W will be a standard product, same design just with a more appropriate COB wattage instead of driving the Duet 60 @ almost twice the power. It will be for sale for around $250-$350 with an option to include a 10 year...

    DUET 2400 (LED FIXTURE) - UP TO 2400 WATTS (Flip Chip Opto)

    Hi Corso312, Are you talking about the 2400W (runs at 50%/1200W) Fixture or the 100W Fixture? I don't have PPFD values at distance yet, we should be getting that by this week. Hanging the 100W from 2 FT from cannopy and 5 ft from floor gives you a grow space of about 4x4FT

    DUET 2400 (LED FIXTURE) - UP TO 2400 WATTS (Flip Chip Opto)

    It's already for sale, but at limited quantities. We're just waiting for our PPFD numbers from our lab, then we'll put our lights online.

    DUET 250 (Fixture) - Prototype Lineup

    Actually, the real question is... WILL IT BLEND? P.S. in less than a week or two we will have each fixture's footprint, from canopy height, radius, ppfd values at different heights etc.

    DUET 250 (Fixture) - Prototype Lineup

    Hey nevergoodenuf, Just got back to the office. We are on backorder for the next 4 weeks. We sold a bunch of Duet 185W, Duet 320W Fixtures running our Duet 250 chip with controller box. The 185W is going to run you at $325 + tax&shipping, the 320W is going for $500 + tax & shipping. Those were...

    DUET 250 (Fixture) - Prototype Lineup

    A simple calculation in our 660nm red is 0.85 µmol/J. 650nm red is 0.95µmol/J; 640nm red is 0.9µmol/J. For exact numbers, we'll have that within two weeks. We'll have our results back fro our LM80 labs.

    DUET 250 (Fixture) - Prototype Lineup

    I forgot to mention, to all the white light fans out there, you can now choose white/red or blue/red on all our products. We may release a design with a combination of all 3. Maybe.
