That is good news EF, do you know what vF and current it is running at?

I Hooked up the multi-meter and it says 37.3V @ 1.46a, that is with the blue and white wires (dim+/-) not connected to anything.

As for dimming I'm going to have to read up on that.

Well it seems I was wrong about how the dimming works. In the spec sheet it says the HLN-60H-42b

Current Adj. Range 0.87 ~ 1.45a

That must be for the "-42a" version of the driver only, when I hook up a 10k Ohm resistor to the dim+/- on the "-42b" it dims to 31.6V @ 0.14a. This is a bonus, as I understood it I would only be able to dim to 0.87a. so with this driver It looks like it has the ability to go from 54 ~ 4.5 watts.

Another update from day 66 12/12 with just two 3070 COBs @ 1400mA each. They grow big dank buds for sure, looking like it will be close to 1GPW on my first go with these COBs and first time running these phenos from seeds, could have been more dialed in for sure. Leaves yellowing and falling off a few a day, they have had a long "flush" last nutes they got I fed on day 47 so buds should be nice and smooth. Couple more days til harvest.

That's what I've been talking about Chroni, fat mature bud except he's crushed my Illumitex grows. That's the kind of bud I only want coming out of my LED grows. I'm liking COBs quite a bit more, no offense Supra :).

GREAT job Bueno, inspiring! Where's the little clapping smiley face when I need him?
