Bonjour
If you buy cxb 3590 3500ºk 36V cd you should think about individual hs to get a perfect light spread...your cxa's can light a 1.5x1.5 area @1050/1400mA about the size of your hs...so why put all your light source in an area that only one can light!???
If you will have 4 x 600hps what will you do?...put the 4 close to each others or cut your room in 4 piece and place one at each center?
Some guys wonder why their leaves bleach?...too many powerful light cones crossing in the middle of the room and weak amount of photon on the sides...if you cut your box by the number of cob you have and put one in the center of each piece you won't regret it!

Good day, LJ.

If I only had one light, then I suppose you are right that instead of putting them all in the tube, I should have instead put them on three different heatsink/fan units so that I could spread the light around, but that is not my only light in the grow area. I do have one CXA3590 on a heasink/fan and it works well and is very bright. BTW, my CXA and CXB Cobs are all 72 Volt versions. But I have a lot of lights in an area that is only 3' x 4'. I also have a couple of Vero 29s running off of two 1.75 amp drivers, an Apollo unit (Apollo Horticulture Purple Sun COB Full Spectrum 384W LED Grow Light) that was 384 watts, about 180 actual watts, with two of purple COBs, one of which burned out and I replaced with a cheap Chinese 3000K LED. I also have my Sforza's Sfolly light that I posted pictures of before, with a 200 Watt center light and four Chinese LED 3000K 100 watt LEDs in the corners. I also have some other single LED lights mounted on heatsinks/fans and I have five more CXB3590 COBs sitting on my workbench along with five Meanwell HGL-120C1050A drivers in a box, so I have plenty of lights in my grow area and in the pipeline to cover my little 3' x 4' space.

What I lack in planning and finesse I more than make up for by throwing resources and watts at the problem. I am learning by doing. The more lights I build, the more I learn. I also have several earlier versions of LED lights that I have had to pull out of use, retire them is the term that SupraSPL uses I think, in order to put my newer lights into service. I will probably give the retired lights to a friend of mine.

I hope so:) still got a few aces up my sleeve...
This actually turned out well but it's a garage light and nowhere near to a commercial unit. And then again, it isn't an easy process to release a lighting fixture in EU that would comply to the law.

So here's an early experiment in light movers; two thousand watt lamps, one each HPS and MH, on a circular light mover... WITH AN EXHAUSTING HOOD VENT. The thing was a kludge; it would burn plants without providing enough DLI, but the air extraction system did a great job keeping the room temperature under control.

Ahhhh, obsolescence... fucking waste of time n money!

Now what in the world would give you that idea...:finger:. Sliding coolers and cheap aluminum boxes..:hump:

Lol...just kidding. I knew there was a reason i never popped the hood on the later versions. Its like when they made lambos on a fiero chassis. All good until you start the engine or look at the interior

Always keep your best ideas for yourself to some extent. Unless your feeling like mother theresa...

To sell panel in EU you just need a chines factory who made light for EU...you.tell them what you want they send you a prototype and if you are happy with it...you give them money and you become a reseller no more no less...so no problem to sell it!
I asked to Isled owners and they don't know if the lights are certified or anything...nobody gonna say in case of fire it was because of the lights I use to grow weed!!! Not in France unless you want to go to jail! So warranty is not a problem for some...!
Or you need someone with a high level
in electronic ...but the chinese solution is the best if they really use the good components and work clean!

I got the copper plate and the copper heat sinks on eBay. Probably have enough, especially considering that I have very little headroom in the area. I just got a little carried away buying COBs and drivers and it is enjoyable putting lights together and seeing how much light they put out.
