The HLG-120H-C1400
fits just fine 3 x BXRC-x0E10K0-D-7x.
It has been already
tested ,
even with the COBs & heat sink at 0°C .
Also the driver operates close at it's 100% load ,
which means also that operates at it's max efficiency.
Galaξ LED grow light by Astirgrows uses 2 x HLG-120H-C1400A and
6 x BXRC-30E10K0-D-73 .No problem at all .

That's a great build. And if I was building them for other people to use I would definitely go with the 1400mA driver. Especially if I had to offer a warranty. If you were to give the user the ability to run at max, 90% of users would run at max, greatly increasing the risk of a burnout.
But for me...I gotta get them micromoles. Lol.
That 6 COBs pushes 42000 lumens on 6 chips. My 2.1A x 3 chip gets 33000. 6 chips would get me 66000 lumens. But as mentioned. I'll probably kill these chips after 2 years.
you really should do some more reading and listen to what
@stardustsailor has to say lol.@1400ma those vero will be pushing 50+watts per cob,not 42w.we look at things much differently with custom cob builds,its not always about max power like hid growers try to utilize.99% of these cob setups you see around here use 50% of the test current or "rated" current because the chip is alot more efficient and lasts way longer this way.it comes down to lpw not max wattage.
@stardustsailor ,that new panel and power box looks kickass,you know we ll wanna know what kind of goodies are between those 2 drivers
True. But a 1400mA driver runs maxed at 50w. It can never go higher. It can never put out its rated 10,000 lumens. You can dim it down but you'll never get it above that. I can run my lower (all the way to zero) and I can push it all the way to 11,000 lumens. So for me, it's either run 3 chips which cost $300 to build and get 33,000 lumens. Or run 6 chips (cost of about $600 to build) and get 42000 lumens. $300 for an extra 12000 lumens doesn't seem like a great deal to me.
Plus Bridgelux Vero 29's are rated for 125°C at the core and test current results are at 2.1A at 85°C.
Maybe you should read the Bridgelux data sheets cuz you are talking like these chips are Cree's. Bridgelux has a higher temperature rating than Cree. Alloy substrate vs ceramic.
If you wanna blow the extra $300 bucks feel free. For $100 I rather drive the newest chips every other year.
It's not like I run them full throttle 24/7. Lol.
