1st I loved ur question thanks
Gotta dig deeper, I can't be arsed screen shotting the whole line up and making a spreadsheet to prove a point
Most ppl here are in the USA so at that voltage arnt even getting %90 efficiency with the hlg drivers
Xlg dims to off, hlg to %10
Cost is much less for the xlg and 3 year warranty vs 5 year warranty means nothing
If U didn't install it in a hot location it will run 10 years
If too hot only 5
Sure the HLG has slightly better specs I agree, if run on 230v

2nd feels like a kick in the guts that this thread is a sticky even though it has no content and especially as those who decided it was worth a sticky have over looked the years of work ive put in here
That is great info there, and something that I hadn't yet looked at. That said, there are a few inconsistencies in that comparison. For one thing, you are comparing a 150watt XLG driver with a 240watt HLG driver; however if you were to compare a XLG-240-L driver with a HLG-240-H-48 driver, the XLG model would look even better for those numbers. Here's the graph for that driver:
However, now we're faced with a different inconsistency, which is that the drivers put out two very different voltages, with the XLG-240-L driver putting out 178~ 342V, while the HLG-240H-48A driver puts out 24 ~ 48V, so it seems to be an inequitable comparison. Typically the more common driver selection would be a HLG-240H-54A (27 ~ 54V) compared to a XLG-240-H (27 ~ 56V) driver, but I don't seem to find any graphs on those specific models.
Also, it's interesting to note that in the graphs you posted, that the XLG is based on a Tcase temp at 75?, while the HLG is Tcase at 80?.
The XLG definitely is good driver, but I'm not sure I'm convinced yet that it's superior to the HLG line, all things being equal. I do see what you're saying about the "hidden wattage" of the xlg line tho, with it being capable of putting out up to 6660mA compared to the hlg line topping out at 4450mA. I am curious about the efficiency of both drivers once you go past the 240watt rating of the driver. Both drivers can produce at least 20% more power than that rating, but the posted charts don't consider anything past 240watts in terms of power factor.
