HLG-240H-12A​

AC-DC Single output LED driver Mix mode (CV+CC) with built-in PFC; Output 12Vdc at 16A; IP65; Cable output; Dimming with Potentiometer

SO i got this meanwell a while back to wire up some cobs...i couldnt figure it out...found another driver and made that work.

Can this meanwell run QB120s? How many?

Or even better....how many citi cobs can it run...

I bought 2 QB120s for it (I just got an HLG120 on order but...WTF do i do with this driver)

I am really glad i ordered the right meanwell...i am just out this driver.

It makes sense why i couldnt get it to work...series...parallell....solid core braided core...wagus and wire nuts.

Man can i wire a board ! All that practice was good for me..

Oh it pains me....let me tell ya
 
I had a random idea you could use the driver for. Rapid LED sells these single violet (410-420nm) LEDs that run at 3-4 volts each. A string of three or four of them in series could be run on the driver, though it's got way more power than you would need.

Anyways, with enough of those near-uv diodes, you could achieve an almost 20% increase in cannabinoid and terpene content, at least according to some tests a few members of a different forum did. I think it would be worth looking into if you have everything else dialed in.
