cree, also have run mono's my led has 4x cree cxa2590 along with some 660, 680 and 730 reds and a UV-B CFL bulb.
Nice how many watts is that pulling? Leds are quite a bit more efficient now. I've ran the mono panels they are garbage but my cxb3070 do pretty well

around 200 watts, I think leds are good but they still got a ways to go, costs are much too high to rationalize a purchase at this point i'd rather just get more HID lights and air condition them.
Those 2590 get around 100 lumens per watt right? The newer ones are getting over 150

they get around 120 , the newest crees and citizens get between 120-160 depending on how hard you push them. not worth it at all to upgrade them at this point they have less than 10k hours on them.
Ya I wouldn't upgrade either but for someone who hasn't made led yet they would be getting 10000 more lumens than you are for the same power and a cheaper price so it's not really fair to compare your led experience to whats available now. I still can't wrap my head around growing with hps with only 4 feet of height if he had a big garage and price is a concern I understand hps but for a 4x4x4 wouldnt it get really hot even with an air-cooled hood?

That's wrong and misinformed. The BEST CXB3590 produces a max of 18k lumens and CXA2590s put out nearly the same lumens at lesser lm/watt.

I meant for your whole light not per cob and it wasn't an exact number it all depend on bin an color and what current your running them at.
My math was assuming an extra 50 lm/w over 200w but with those numbers I guess I was wrong it's only 40lm/w more so it's 8000 more lumens

I would use these for a budget build they perform a little worse than 3590 but better than 2590 4 of them would cost like 50 dollars

Maybe reduce plant number to 4 and then canopy it under T5 lighting. You may get wider but shorter pots with only 4, potentially leaving enough height for a 400, dunno if that would be better than T5 in that setup though.
Only other thing I'd consider is putting in lots of little pots in a sog as you'd then have the height to use a 600.

I average 4.5 - 5.5 ounces per plant. So I'm good, thanks.
I hope u have at least 4 plants per light

You can get a 400w MH/HPS combo on eBay for $90. I have one and it's working great. It comes with a reflector not an air cooled hood, but 400w doesn't produce too much heat so with a fan or exhaust system it's fine.
If you do that and then just place your existing CFL's around it you can easily cover a 4x4 area and you will have plenty of wattage.

I either have to dump or get off the pot. I would like to go DIY but I'm really still unclear how many of what COBs I need for a 4x4x5 area. Is six CBX3070's or CXA3590' enough and what sort of mix of COBs should I be aiming for. Do i need Cree or Meanwell drivers or can i save some money on that end? A blend 3000k, 3500k or 5000k or just all of one kind. I'm prepared to leave room in the array for supplemental lighting not requiring a driver. I would pull the trigger on the solar storm but the coverage area for flowering is only a 3x3 footprint but for vegging it's 6x6. I'm coming out of the gate with two 4x4x5 foot sections so I've gotta double down right from the start. I'm either ordering the stock to DIY today or ordering TWO fixtures. I just can't get a handle on the DIY path. I can wire chit up with no worries I just don't know what to wire. Thanks for your help and I'm going to go find a sharp stick to jab in my eye.
