Buy a Meanwell......... you'll be much happier.

Every driver I own is a meanwell, I never buy generic crap when it comes to electronics(although I'm thinking of using crappy star diodes for a 660nm and 730nm booster bar). But if you notice, the LP series even for Meanwell has no ground cord going to the driver for the AC side, I'm looking at the LPC-60-1750, the efficiency is 86%.

Why do the smaller drivers never have a ground cord? Are they not needed? My AC plug would only have the double prong correct? Whats the safety concern there? I'm used to cobs so the larger drivers always have a ground plug. Thinking of having this a 30by30" just for small veggie seedlings.

Would that be good @robincnn @Stephenj37826

Its not because its smaller, its a class 2 device and does not require one by certification standards. I believe the cases are also waterproof.

Man I'm so anxious to get my 260w kit from Growers lights. But it won't be in till the 14th!
I wish I would have pre-ordered straight from HLG, I may have had my lights by now. :sad:

I really like the idea of the QB120 at the old cob standard 36v.

Wondering if you guys are planning on getting heatsinks to suit and offering a version with similar connections to the other quantum boards? Dreaming of directly replacing my cxb3590's with qb120's on sinks would be great. Ease the weight stress on the tent and increase efficiency of the lights.

I realise there isn't a need for sinks at such a low drive current but having a slate 1 equivalent for the QB120 would be cool.

Forgive me if these things have already been suggested or discussed.

QB120 is 24V designed for lower wattage with no heatsink and 40W kit with a GSC-40B-1400
Are you trying to use the driver you have for cxb3590 for QB. What driver are you using ?

My mistake, I had it in my head the QB120's were 36v. I dont actually have one here, apologies for the confusion

I was just thinking out load about all the cree cob gear I've been running prior to quantum boards. That all of my previous lights were built around 36v cobs. (cxa2530 cxb2530, cxb3590) on various CV and CC drivers but all of them fit 36v chips in desired amounts.

Having a 36v QB equivalent on slate 1 style heatsinks as a simple light engine swap would be a fantastic way to upgrade all 36v DIY cob bars out there. Instantly upgrading efficiency and reducing weight

This was where my mind went when I heard you were desiging a smaller board than the QB288 and QB304

@Stephenj37826 and I have been thinking of a board that can use the 185H-C1400 and 240-C1750 drivers. Would make it easier for people with 3590 setups to upgrade to QB and use the same driver.
If we had a 36V board then you will have a 1:1 replacement for 3590 on same driver.
We think a 70V board or Dual channel 36 V be better, then each board can replace 2x 3590 on same driver.
