    DiY LEDs - How to Power Them

    Quick stupid question here, what is the math for running a cob? Say i have a 50W Cob and want to run it a 1.4A how do you calculate how many watts its going to put out in order to match it to the driver? I know its something stupid simply that i am missing here and hate to even ask because i...

    DIY Citizen Cob LED grow

    Thats what i thought just wanted to make sure. I imagine you hook both hot wires on a 220 setup to the ACL and ACN lines and ground to ground?

    DIY Citizen Cob LED grow

    Looks great! Quick question, running them at 220 does it change anything? In other words would the HLG-240H-C1400A still be able to power 3 1825 at 220?

    CXB3590 3500K DB 36V

    Or even the 1825, i see you sell those in the 6th gen. Im going to imagine those are more efficient than the CXB and the same price. What are the driver mathch ups that are used?

    CXB3590 3500K DB 36V

    Honestly been out of it for a long time and simply do not know where to start with a new Chip. How much better are the cxm32 and what are they going for?

    CXB3590 3500K DB 36V

    Efficiency is one of the biggest for me, I rather spend a extra grand and make back 3-4 over its life compared to one using more electric. Plus i can get a more even spread with 20 CXB running at 1050 and still have plenty of penetration.

    CXB3590 3500K DB 36V

    Have any side by side grows between a CXB and a comparable model? I would like to see them in action before pulling the trigger on a cheaper chip.

    CXB3590 3500K DB 36V

    Comes in second behind the cxm22 if these numbers are correct. Everything i have dug up its 66% efficiency on the DB

    Anyone know the efficiency of the CXB3590 3500K DB 36V at 1050A and the watts its putting out? Ive been looking for a spread sheet on it and not finding anything. Thanks in advance

    CXB3590 DD bin where to find them?

    I was under the impression the citi 1818 was not even cracking 50% efficiency at 1.05? While the CXB DB are hitting 66%? I rather worry about the cost of electric adding up than the cost of building it. Sorry i meant i will not be looking to by for 4-6 months as it will only take a few days to...

    CXB3590 DD bin where to find them?

    Are they brighter and equally efficient? If so what would you recommend? Makes you wonder what they are waiting for to release the DD. I am primarily looking to build the veg light in about 4-6 months so in no rush just making sure all of my research is down long before i am ready. I rather go...

    CXB3590 DD bin where to find them?

    Anyone have a source for DD bin? Are they just now coming out? I asked jerry and he does not have any and will not in the next 4 months. Best i have seen are DB and they are extremely hard to come by. I finally decided on the light and now i cannot source the COB's anywhere. Was really looking...

    4x4 Veg light suggestions

    I am looking to build a 4X4 veg light and was going to do the CXB3590 but i seen they are no longer the best. Anyone have any recommendations on what will be a good cob to run? If i can get the same efficiency and not spend 40 for each one that would be great. I am looking to run them around...

    Heatsinks for DIY LED lamps

    I will actually be doing 3 of the in a 2x4 so it will be dam near wall to wall heatsink. 2 on the outside will have 3 cobs on each and the middle will have 2. I will probably have 4 cobs on them in the future. Trying to plan ahead.
