Tell ya what; do a full on side by side and hold the watts driven constant; that is, for every 315W of CMH, run as close as you can to 315W of COB LED. I did this and I was convinced.
All BS set aside CMH yields

Sunplix has a ballast out designed just for the allstart 860, it dims and also boosts to 1kw. They boast "the first lfsw ballast made to run the allstart 860 " but I know of two other ballasts that have been around for years that will run the allstart 860 to it's potential.

Would love to but that would require more veg space or running a smaller footprint under both fixtures (which I wouldn't want to do as it wouldn't really show me what they can do). I have 300w of COBs which is about as close as it comes to the LEC, just need additional veg space to fill 2x 3x3's or 2x.3.5x3.5's simultaneously. Will get to it but no time soon, we get a short summer here so I'm kind of in a holding pattern until end of summer. Too many other things to do outside while it's nice out
What I may do just because my holding pattern through the summer could allow it is something like a 3x5' or 3x6' with the LEC in the middle and 100w of COBs on either end, maybe a 3rd 100w angled in the center. Would love to see what mixing up both spectrums can do for both quality and yield...

Yeah the onyx were 3070's if I remember right, not bad but I found a huge difference between the 3070's and 3590's. From what I saw the 315's out-produced the 3070's easily while the 3590's are probably going to out-produce the 315 watt-for-watt. Haven't run them (3590's) enough to get real numbers. 1st run though produced 390g from 300w of 3590's and wasn't even pushing them, mix of 3 strains, 2 from seed with real no training other than a super-cropped main. That tells me they have some room to out-produce the 315's.

actually they were xml2 but at least the proper spectrum and there are 28 of them per onyx so......

Well I'm headed that way so looks like I'll have the opportunity to try it next round, in about 4 weeks. I have 4x 3gal that'll go into 7gal in the next few days and nothing else coming up in veg, I'll have to skip another perpetual round but not like I need it, my outdoor is on it's way to a couple of elbows
3 are from seed though but I have 1x Blue Ripper in there that I've run under both now so should get an idea by converting the yield to grams per gallon of medium.,

No reference with the xml2's, never ran those. What has sold me the most on these 3590's is the terps are through the roof in comparison to anything I've run. No explanation why that is but after a couple of rounds with one pheno I've run under 3070's, 315's and now 3590's, the 3590 buds are triple baggers. Anyone I gave samples to of the 3590 buds thought it was a new strain, crazy difference for just a lighting change.

Uh, huh? I don't mean to sound rude, but let's try that again with complete sentences.

I got it used and in fact it's a loan.
You can use the old Bad Ass Ballast from Advanced Nutrients, or the Hortilux Platinum ballast; both of these are discontinued and available intermittently used on ebay and the like.
There's a new unit for sale called the DeVa from Revolution Micro, advertised here on RIU. It's a one piece fixture, designed for DE HPS or MH but it's also a LFSW ballast.

yes, yes I can: the grower is called cali crop doc: there is 7 eps, he is legit, his room clean AF. you can just watch the last one, but they all have very good points or comparison.

That is correct, both in theory and in my current experience. So while the lamp is labeled 860W, the driver determines output, same as always. It's called an 860W because Philips says it can be run on 208V three phase, that's 14% less than 240V. If the driver says it's pushing 1000W into the lamp, it most likely is doing just that.
Think of it as the output of three 315W CMH lights in one.

Hortilux is still advertising the platinum, I don't think they'll discontinue it. The guy asking about the sunplix, msrp is 649 US. Nobody in their right mind pays msrp so contact sunplix about a distributor in your area, I would imagine they will run around 4 bills, that;s all I'm willing to pay but I've given up since the distributors around here don't do a very good job.

if you poke around threre is a few more: but phillips makes the agro 4200/3100 but I'm interested in the ushios, it was 3000k and was deep in the left.
soils tek also makes on that is 3100k that had a lot more red then the phillips 3100k, which would make it a better all around bulb.
there is a couple more and at canna expo: expect a few other popular manufacturers to make an offering, although it was stated, "oh we loved to make a chm bulb and have plans" type of answer. take that at you will.

Swap your HPS for 860W Allstart lamps on a one for one basis, as I did, and you'll see better frost but your yield may suffer a bit, this on magnetic ballast. If you do it with LFSW drivers, your yield will be comparable or a slight increase, again with better frost.
This is what my own experience has suggested thus far, at least.
Run the lower Kelvin temp for bloom, which works fine for my veg anyway.
Remember, the 860W Allstart is vertical only and so light movers will likely make it swing around. That shouldn't stop you, just be aware and plan accordingly.

Take it seriously; I've heard several manufacturers are looking to do 1000W CMH DE lamps.
