What are my options for driving 12 Bridgelux Gen 2 560mm strips?
https://www.digikey.com/product-detail/ ... ND/7907664
Hoping to see two options - budget and Meanwell HLG.
Newbie here, appreciate the help.

As a budget option I was running 6 on meanwell xlg 200-25v, which cost us 30$ when we took over 10. There are 40 and 75w Thomas Research Products drivers at digikey that are a bit less efficient, but work well with EB's
Then you have meanwell ELG and HLG series which are common. There are different models, HLG series has a 36v driver that can be pushed to 39v if you are running 2-series on low current, and there are 22v and 42v models.

Thanks man that's the kind of detailed answer I was hoping for.

Oh, and I always forget, the ELG series is a bit cheaper and less efficient, but it looses power if you use it with 110v electricity. All the others should be good for the US, incase your there

I run 14 bridgelux EB gen 2's - 2 footers using an HLG-185H-C1400B. It is a 200 watt driver, and I run 7s2p. Works great and the lights stay cool @ 700ma max. I think the voltage range on that driver is 71-143V with 1.4A max.
Running 7 in series puts me at 136.5 volts (per series).
Series of 12 puts you at 234v, so probably a little high. If you are running at test amperage, (0.7a) you will need a driver that can put out 163.8 watts (234v * 0.7a). I believe an HLG-120H-C1400 puts out 150 watts. So it would be a little low. I think the next closest to 163.8 watts is the HLG-185.
If you did 6s2p on an HLG-185H-C1400, you would be at 117v on each series, running 0.7a for a total of 163.8 watts.
Whether this is the most efficient route to go, I will leave that to the experts. If you had an extra few dollars, I would suggest this driver as it is cheap ish, and to buy 2 more strips and run 7s2p.
Cheers,

just a heads up but your 7s2p set up is pushing a higher voltage through the connectors on those strips than they are rated for at 60v. Keep us updated on how that works, I always thought 60v was very low rating.

Thanks! Missed that little tidbit of info and the knowledge of how it applies to my builds... ON ALL MY BUILDS
3. This product has been designed and manufactured per IEC 62031:2014. The working voltage designated for the insulation is 60 V d.c. The maximum allowable voltage across the module must be determined in the end product application.
Can you expand on how this may affect my build?
