Meanwell XLG 320 vs HLG320

What are the main differences between these two drivers?

I see the XLG is rated at 315w @ 93% efficiency and the HLG is rated at 321w @ 95% efficiency. Is the 6 more watts worth the extra money? Why or why not?

I believe the main difference is in the warranty.

XLG series meet newer regs and have added safety features. Otherwise they are basically the same.
XLG are up to 94.5% efficient, HLG up to 94

Can the XLG be pushed to over its rated wattage of 315w? The HLG draws 330 from the wall.

No idea.
You are right about the hlg 320. Mine max's out at 331w, although i dont run it that high.
If you want more watts simply buy a bigger driver.
Your fixtures voltage and current is what dictates wattage, not the driver.

I'm guessing it can pull 320... But I'm not sure. Will do some research

The xlg will also do a better job at hitting the rated power because they have more flexibility with voltage & current. Ie if you used a hlg-320-48 driver on strips that run at 44V, that leaves 4volts (and ~27watts) on the table, while the xlg will bump up the current to 7.3A to hit 320watts.
This forum is filled with people wondering why their driver isn't pulling what they expected because their LEDs don't run at the max voltage.

This doesnt really make sense to me. CC drivers supply a certain current and adjust voltage accordingly.
The confusion on the forum is mostly due to people non understanding what matching a driver to a fixture means

XLG is constant power which is great. For example if your PCB draws 44V only but the driver is putting out 48V it will drop to 44V and give you extra años. So basically helps you maximize your driver watts bang for your buck. Also the XLGs all have dim to off which is nice for setup with controllers.

Correct, HLG is 7 years and XLG is 5 years.

Whenever you want the low down on meanwell drivers try to get a hold of the report, just google model nr of the driver in question and report, it usually takes you thru to the right meanwell section. The values on the report is what youll get 4 outs 5 times.
The xlg is a bit different than the hlg, it usually has a wide voltage range meaning it can be somewhat hard to figure out which one would give you more juice. My guess, if your board voltage is really close to the rating of the driver then HLG. If your voltgae is slightly over, or if its a bit below, then the xlg would probably give more output. But were talking a few watts only. Having run both hlgs abd xlgs i prefer hlgs; lower case temps and generally better quality. But the xlgs is great for adaptability to many voltages.

Xlgs are smaller and lighter too. Though I've not compared the higher wattage ones.
Used to be a lot cheaper but don't seem to be now.

Hi, appreciate your answer, it was very helpful. I have a question for you since you seem to know a thing or two about this.

Ok. So the HLG qb288 is run at max 3000mA @54v with a Meanwell HLG-120H-54A LED Driver @ 135w. Total diodes is actually 272, not 288.
https://horticulturelightinggroup.com/products/qb288-v2-rspec-quantum-board?_pos=1&_sid=fc8565918&_ss=r

The ChilLed 160w bar (295 diodes) tests at max 3500mA @ 45.85v using a HLG-150H-48B for a total output of 160w.

So here's the question. What would be the optimal input voltage (VDC) and input current (mA) using a xlg-320 to power 1224 diodes. 72 Osram 660nm top bin, 576 x 310b top bin 3000k, 576 LM301H EVO Mint White highest flux.

Or

1344 total diodes- 72 reds, 672 lm301b 3000k, lm301h Evo Mint White highest flux?

Looking for the sweet spot in terms of efficiency using the xlg-320

What's funny?

you'll find that info in the specs, efficiency vs load chart

Ok... I don't know what any of that means tbh... And I don't know how it applies to my examples. I'm getting 7111.111mA for 1224 diodes.

Looks like HLG took down the efficiency chart on the website for the older boards.
The desired amperage is up to the user. After that is set, the driver will self adjust the volts needed to overcome the voltage drop over the circuit, as long as it is under the max rating.

For example, if a driver has a working limit of 60V it can power 48V and 56V boards, but it would not drive a 72V board.

hey man, thanks for chiming in. What exactly is a 48V or 56V board? I mean what constitutes it?

I'm tryna run 1200-1400 diodes, 72 red, the rest top bin @ 2.8-2.9amps ...

And I'm using xlg-320H
