It depends on what space he's lighting up with them 8 boards.My buddy ordered 8 of the hgl qb288 v1 boards and would like to run the boards off of one driver. What would be the part number for the driver he needs?
He got it taken care of. Thanks.It depends on what space he's lighting up with them 8 boards.
I will let you know when you reply if you haven't already sorted it
You'll need to turn your vO potentiometer screw counter clockwise slowky with it all wired up and on to get the voltage right. Those are 50V cobs and your driver barely hits that. Luckily it can at least. Also, yes they can be run at 100w a piece but you'd be safer using 8Hi, I've recently built my first light. I've got an HLG-600h-54A driver and six Bridgelux Vero29 BXRC-30E10K0-B-73 wired in parallel. I was just wondering if I can run them at max or close to it? Not willing to try it because I don't want to burn up my cobs.
What? A -54 driver barely hits 50V?Those are 50V cobs and your driver barely hits that.
I'm 99% positive you can't use, say 27v strips on an HLG-480H-54A. Someone please correct me if I'm wrong...I dunno man, I'm looking at a specs file for the hlg-600h which is dated 2018-9-18 and it shows 45.9v, they've been there for years. Not to mention that this range (45.9-56.7v) is only the upper range of its voltage limit. The lower limit is 27V.
Look at the test report, under Constant Current Region, 11.38A at 27V and 11.43 at 53V.I'm 99% positive you can't use, say 27v strips on an HLG-480H-54A. Someone please correct me if I'm wrong...
Yes, you can run it using that driver but its far from ideal, youll only get just over 200w out of that driver which is 320w. This means driver efficiency will be affected downwards normaly, amount is in the datasheet. Best to try to run drivers close to max for peak efficiency.Hi everybody !
I'm building a setup with 4 times Cxm22 gen4 at 3500k ,50v, 52.8 watt, 1,050mA
Can i drive these 4 led cobs in series with an HLG-320H-C1050B ?
Will the voltage auto adjust to the need of the leds ?
If anyone can verify this would be a right choice please let me know.
Thanks in advance , Joe
Thanks for the quick reply ! So ELG-240-C1050B would be better ? , i read somewhere you need 1/3 more driver capacity than actually used because of the peak power when turning them on ?Yes, you can run it using that driver but its far from ideal, youll only get just over 200w out of that driver which is 320w.

The HLG-240H-C1050B will come closer to maxing out the voltage with 4 CXM 22 Gen 4, and will run more efficiently( by a percentage point or two) than the HLG-320H-C1050B considering that the load percentage will be higher.Hi everybody !

Thanks a lot for the help Barristan! I read on a website the driver capacity should be 1/3 higher than the actual use because of the start up peak power. Is this not true ? I'm a little confused. And does the driver regulate the voltage automatically to get the optimum voltage for the leds ?The HLG-240H-C1050B will come closer to maxing out the voltage with 4 CXM 22 Gen 4, and will run more efficiently than the HLG-320H-C1050B considering that the load percentage will be higher.
ELG-240-C1050B would also be suitable and save you a few dollars.Thanks for the quick reply ! So ELG-240-C1050B would be better ? , i read somewhere you need 1/3 more driver capacity than actually used because of the peak power when turning them on ?
I'm running on 240VAC, so the ELG would be 240w , but what's the difference other than the price ? Specs seem about the same or am i missing something ?ELG-240-C1050B would also be suitable and save you a few dollars.
Are you running on 120 VAC or 240 VAC?
Do you have a link to where you read that about driver capacity?
The ELG version drivers are only recommend for +200V AC, theres downrating on 120V. If your on 120V use the hlg240h-c1050Thanks for the quick reply !

Ok thanks for the help Rocket Soul I read in the datasheet of the meanwell, Inrush current: 75A. Maybe this is the maximum current for the leds to draw when they start up ? If so it would be correct i don't need a larger driver and the statement on the website wouldn't apply to this driver.The ELG version drivers are only recommend for +200V AC, theres downrating on 120V. If your on 120V use the hlg240h-c1050
The extra capacity youre talking about: this is with regards to AC fuses but can be avoided by not switching multiple drivers at the same time. You dont need extra capacity on your driver though.
