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 :shock: :? :oops:
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?
