    building a 750w LED fixture from high bay lights

    Oh and I also found THIS reddit thread through google, details another sinkless eb3 slim build that looks pretty solid.

    building a 750w LED fixture from high bay lights

    wow so much good data, still reading through everything but I found the Series 2 on digikey, its way at the last page after the gen 3 even when you search eb gen 2. But unfortunately right now looks like the 4 footers in 3000k are only available in quantities of 100. Good price though- S7.50 a...

    Okay so the eb2 is still available and even cheaper+ heatsinks fully optional?? THAT sounds like the move!!!! Love that fixture btw, nice use of some closet shelf, I actually have some refridgerator shelves like that I need to find a use for.

    building a 750w LED fixture from high bay lights

    Okay, I dodnt realize there was a gen3 slim, ho AND regular version. All I saw on digikey was the ho and slim. But I am just getting used to using digikey. It can be hard to find something on there without knowing the part number. Love the idea of using a wider heatsink and running 2 per piece...

    building a 750w LED fixture from high bay lights

    I was planning to run them on something like 1 1/2" wide 1/8 inch thick bar stock aluminum or could go with angle in the same size if it needs more of a heatsink. Wasnt planning to run them I was planning to run them on something like 1 1/2" wide 1/8 inch thick bar stock aluminum or could go...

    They also make a High output version of the bridgelux eb3 strips that produces basically double the lumens as the slim version BUT at 1400ma instead of 700ma, and the efficiency stays the same. these are even more cost effective too, I wonder how they do that as both have a single row of chips...

    building a 750w LED fixture from high bay lights

    Okay so after thinking about it some more and doing some more research, and taken the feedback I have gotten into consideration, I am thinking running 2 drivers in parallel is just asking for trouble that I dont need. I am curious to see how it works and may do some experiments and testing with...

    building a 750w LED fixture from high bay lights

    They are ul listed sosen drivers, I dont think they are any better or worse than whatever I would buy instead, but running them in parallel could be iffy, and your absolutley right about the number of unknowns with the strips. I just emailed growdaddyleds to see about getting some more specs...

    building a 750w LED fixture from high bay lights

    Would it be possible to wire two of those ufo drivers in parallel? I cannot find the Fv for those lm561 strips I posted the link for, it just says 24v and 1800ma reccomended maximum. But if those drivers are 200v at a max current of 750ma, could I run 2 ufo drivers in parallel to power some...

    building a 750w LED fixture from high bay lights

    Sorry, been super busy the past couple days trying to knock out these room renovations so i can move the girls back in. The strips I was talking about are lm561 24v strips with a max current of 1800ma from growdaddyleds.com, link Here. They have 12 48w lm561 strips with heatsinks for $240 and...

    building a 750w LED fixture from high bay lights

    Yes, those drivers are the drivers on the ufo's, was hoping to use some of those drivers to power all the pucks on the ufo's, running them at a lower current to up the efficiency and free up some drivers to power some other strips. While I am not aware of any regulations regarding working on...

    building a 750w LED fixture from high bay lights

    Okay so I dug a little deeper and found the sosen data sheet for the drivers, here is the LINK. tried to do some copy past from a pdf but didnt really work, but its constant current driver, 150W, 180-260V voltage range 240V-260V voltage out max 0.52-0.75A Iout. The voltage on these looks a LOT...

    building a 750w LED fixture from high bay lights

    interesting, would deff be interested to know what diodes that uses and how many, and if they really use meanwell drivers. Honestly I am more skeptical of amazon than I used to be, getting to be alot more wild west than ever as far as different shady vendors and stuff. still though could be a...

    building a 750w LED fixture from high bay lights

    Yes it seems like they are all in a race to have the highest efficiency, and the higher color temps/more blue led's are slightly more efficient. But for me the efficiency is just an added bonus and not a deciding factor, the total light output and spectrum of the fixture are much more important...

    building a 750w LED fixture from high bay lights

    Wow, just checked out your website. Love your full spectrum- but with LOTS of red on your buddies and led boards!! It seems like a lot of manufucturers have gone with more blue based spectrums but I have been looking for something with more and broader red. Those buddies look like they have...

    building a 750w LED fixture from high bay lights

    Very cool! Those diodes look like they would be perfect for supplimenting the red and far red/ir all at once, seems more natural to me as well compared to two different bumps on the spectrum. Any plans to build a panel or strip with these diodes? I need to get on the computer and check out your...

    building a 750w LED fixture from high bay lights

    Will have to check out those suppliers on alibaba, I have looked at a few different complete fixtures on alibaba but with so many suppliers it was hard to find somewhere to start and narrow things down to the best options. I am sure the shipping on led boards will be much more reasonable than...

    building a 750w LED fixture from high bay lights

    Yeah I had already sealed/waterproofed them to address some moisture issues and prevent the possibility of mold. I kept after it last night and ended up just strapping out the walls with some 1x so I would have something to mount things on and attach the poly too. In the future I may cover the...

    building a 750w LED fixture from high bay lights

    Thanks for all the reply's guys, have been super busy sealing, insulating, waterproofing etc. Still trying to schedule a time to pick up the ufo's but he has me down for 5 and said he will cut me an even better deal if I want more. Tempting but there are a ton of things I still need for my room...

    building a 750w LED fixture from high bay lights

    Those buddies are pretty cool too, I am all about some side lighting, that phosphor coated red diode is something I havent seen before, I wish they had a spectum chart to go with that color. Going to meet the guy in the next couple days, excited to actually get them in my hands so I can get a...
