Much less than it would cost for a premade fixture. Ask @CobKits
There you go mate! It's really worth to invest in those lights and delivery is super fast!
No I'm not in the UK I'm in the states
DIY can get you close to 1$/watt. Strips and boards are usually the lowest cost with cob next, depending on how many arrays you want to run.
Yes strips are better than Cob. Better lumen/photon per price. Better lumen/photon per wall watt. No heatsinks required with EB Gen2. Better uniformity.
The description says they're using QB288s (they also use the term "Quantum Boards"), but I don't see HLG's branding stamped on the boards in the picture, and the diodes are in an unbroken line from one end of the board to the other, like a QB304. I don't have a problem with another vendor selling PCBs, but if Timber is using non-HLG LM561C boards (that are designed to look like QBs), they certainly shouldn't call them QBs. That's HLG's brand-name. Also noteworthy is the fact that they're S5 bin, which further persuades me that these aren't actually QBs.
Awesome. Thanks for the clarification!
Pretty sure PPFD/Intensity, COB > EB watt for watt. Maybe more dispersion, but less intensity.
Wanted to thank you for the Veteran’s Discount, by the way. Really loving the 2VL. Are you using the 90 CRI or 80 CRI? I really like the passive cooling. No fan noise! If I were to buy a Citi kit, could you give me or sell me at a reduced rate, the pieces to attach them to the frame of the 2VL?
~$550
I was going to say ~$500, but wasn’t sure.
Buying an AC unit just increases your electricity cost. It will never really pay for itself. OTOH, a good quality LED fixture will use about 30% less power, essentially paying for itself over time while lowering your heat issues.
You can DIY a 600W LED strip fixture using Samsung F-strips or Bridgelux EB strips for under $400.... That will just about replace the 1kW HPS.
