Driver selection for QB288

I'm wiring up 1 QB288 and was wondering if the ELG-100-54B-Y3 would be suitable? Eventually I'm gonna by another quantum board and just connect them both to a 240H or have them both on 2 separates
I've been browsing around and using the driver selection tool and found it is only much help for more lighting.
Thank you in advance!

That will run your board at 100w. On the 240, they'll be at 120w each.

Sweet, so thats perfect then as the driver runs 1.77mA pushing the board at around 96w? I tend to second guess a lot, hence the thread. When I upgrade would you recommend getting another 100 or connecting both boards to a 240?

Hey man, are you using 120VAC or 240VAC for your electrical source?

FYI if you are using 120 VAC with the ELG-100-54B, you won't be able to utilize the full wattage potential of the driver(only about 70% or 70 watts). According to Mean Well,"de-rating may be needed under low input voltages"(180 VAC or less).

So you run them at 2800mA? I've heared they'll be brighter at a lower current?

Don't necessarily run them at 2800mA all the time but it's nice to have that option. Plus I have my lights as far up as they can go in tent I feel like I get a much better light spread.

No not brighter, but more efficient. Higher lumens per watt but still less lumen output.

He's spot on. In other words, at a lower drive current, there IS more light coming out of the diode on a per watt basis, but because it isn't a huge leap in the amount, it's still going to be less bright at a lower current.

I get you so it'll be weaker but last longer due to being run at lower power? If thats the case I think I'll get the 120H-54B at 2.3a.
Thanks guys appreciate the help
