same here. I wonder if those are the originals that were in it?Excellent! Strange, those look different than my Citizen 1212 gen5 cobs.
Thats the chinese one i replace them withsame here. I wonder if those are the originals that were in it?
its not wrong at all, although 1 cob per square foot is on the upper end of what most people run. the citizen 1212s are an excellent choice at 1 per square foot, check out @DesertHydro 's grows for some great 1212 actionAm I wrong in thinking 1 Cob per square foot ? Would rather drive more COB's softer than fewer harder for efficiency sake.
lotsa options on driversSo let' just say 24 cobs over a 4x8 can u recommend what drivers to run? Also do you sell the chips your talking about?also do you give discounts on bigger orders.I would need 72 cobs and whatever drivers and heat sinks to run them
Was thinking 4 of the Lumins and running the driver outside of the tent. Want to be at 185-200w maxits not wrong at all, although 1 cob per square foot is on the upper end of what most people run. the citizen 1212s are an excellent choice at 1 per square foot, check out @DesertHydro 's grows for some great 1212 action
3500k 90cri ??Looking into 4 Luminus CXM22, using a HLG-240H-54B in a 2x2.. my final light rig set-up, enough BSn,lol..
Yes, and going to get the 320H-54b instead of the 240, $20 more bucks well worth it i reckon3500k 90cri ??
just put 20 more up on siteYo CobKits, Are u getting anymore of the Mechatronics IceLED Ultra active heatsink for the cxm22's in any time soon?
the 240h-c1400B maxes out at 179V and can only run 3 50V cobs. HLG-240H-54B would be a better choice to run 5 cobs, but in either case youre not getting 1400 mA x 50V x 15 cobs out of 3 hlg-240 drivers because that is 1050W of cobs which 3x 240W drivers cant provide.I opted for the 1400s because I will eventually want to grow taller plants and feel like maybe I may need the better light penetration.
yupAfter researching more i dont think i can use the Luminus CXB with that driver at 5 cobs per driver.
theyre not more popular because of their lower voltage theyre more popular because they are riding on their name recognition from years ago. cob voltage matters little in your overall design. a luminus at 1050mA is both brighter and cheaper than a cxb3590 at 1400 mA despite using similar overall wattage per cob.I can see why the CXB3590 are popular cause of the voltage range you can run them low.
it would give you 700W, but so would 5 luminus on a 240h-54B. same overall wattage, less current per cob due to higher voltage per cobIts the only configuration i found where i can run 5 cobs on the 240H and give me around 700 watts per 4x5.This is what i am gathering from reading.
a 240h-54B would give you between 0.95-1.0A per cob, or ~50W per cob/250W per driverOk i see i can run them at 700mA and be able to run 5 of them per driver.Im going to check out your website now.
