It's my own production.

~250 umol/s

My replica of Holographic Series. Long AC and fan in final version. Much cheaper than original one. I was too lazy to look for something like "hololens" so I used acryl glass 2mm thick.

Just trying make it simple:

Just trying to step aside from those cree "bobs". 4xSeoul Semiconductor 3000k, L1G10E ($10 each). Whole 255w. Lens 90deg. 4xMeanWell LPC-60-1400. FotonFlux without lenses ~25k lumen. Vent and cooling 2*Bitfenix Black 120+MeanWell LPH-18

CAN700 is done Next will be Citizen or Prolight, seems they can kick some Cree ass.

From largest forum of growers in my country - olkpeace.org, there is a man who has done a voltage drop research for a decent amount of cob's. here's some photo: The Vdrop of cobs from USA is about 0.01-0.05v, Chinese 0.3-0.5. Looks the same.

Excuse me for my thread choice, but i lost that thread where cob's from Jerry KB were discussed. I have got some info showing a huge amount of low quality Cree CX* chips were dropped at at Chinese market (Ali, KB). There wasn't such info before, but now, with growing popularity of those cobs...

It was a custom order, 6 * XPEPHR-L1-0000-00801+1 XT-E CW on one base. 12.5$ - each

New light is done, is it bad that minus cable is slightly longer than plus, i thought it'll be better looking, but i don't know the cons.

Hi everyone,just making things clear. Two Elg-100-1050 to one 100k dimmer pot is ok?

Is my scheme is ok?

Hello again. I'll plan to use 2 x ELG-150-C1050B for 3 x 2 CXA 3070, there is a voltage surplus, as ELG have 143v and 3 cobs will drain 37*3=111, so i have 143-111=32v rest. Can i use this voltage for a n*660nm XPEPHR for example, they have 1000mA max according to datasheet so they have to work...

Does anybody worked with programmable led drivers? With KNX/DALI 2.0/Smart timer dimming functions?

Do your cob's best

Excuse me, sir! You're fix ideal holders by capton tape? OMG! I suggest you never do like that if you want your cobs live long.

Final Phase, Passive, 30w per fixture.

Pos, i'm delighted by your new light, why are you using ledil reflector holders instead of cob holders for the cob's fixage? My last light also had them, but i'm not sure about their durability and pressure, so i decide to use only an ideal holders with reflector adapters. What is the part...
