DIY with Quantum Boards

If you're trying to get a cheaper alternative, look at the LRS model meanwells. They need to be mounted outside the area since they're in an open metal case, but they're great for the price if dimming isn't needed. They can't dim.
They come in 50/75/100/150/200/350watt
and are Constant Voltage drivers. Not CC like the HLG model has versions of. But parallel wiring is usually safer and not too difficult to work with. The LRS line has the same options. 3-5/5/12/24/36/42/48/54
Probably missing a bunch of voltages but that's a few for sure they come in
Oh, shit, thanks

Not so much cheap, just good bang for buck. I just now ordered ELG-240-C2100B. It does 180.6w @ 120v. Thanks guys!

You'd have to go up to the HLG-240H-C2100, and dim it back to get to 200W.

Nothing wrong with using an ELG.
We're talking about basically negligible gains in efficiency by running at less than maximum.
On 120V which one is ultimately the more efficient of the two?

Without looking at the data sheets, it seems I recall the HLG beating it out by a few %.
I feel like the ELG had a shorter warranty as well.

Now, if we're lighting up a warehouse, those extra few % count big-time.

I am trying to decide between the 320W (3 288QB boards on a long heat sink) or 360W ( 2 96QB boards) for a 2x4 area. Can anyone give me a reason to go with one over the other.

From all I have read they seem to be equally capable, but I am wondering if one has more penetration, cooler temps, etc...

Thanks in advance!

Not used the QB96s but if your height restricted I would go for 3 boards since you would be able to get closer , plus better light uniformity, but that's just my opinion.
