CXB3950 / 36v vs. 72v

Hello guys,

My question is about CXB3950 and may have discussed here in the past.. I've ordered a kit built on 4 x CXB3950 36v COBs with HLG-185H-C1400B driver, but they made a mistake and supplied the 72v version of the COBs. I had to read for a while until I understood that I need to run the 72v COBs in a two parallel pairs of serially connected COBs arrangement.

So my question is, in terms of lumens, heat or cost - is there any difference between this '2 serialized in parallel' configuration, and the original 4 serially connected 36v COBs configuration? Are they identical?

Please see the attached illustration of the two cases..

Thanks for your help

yes

did you order wrong or did they mess up

if its the latter just make them swap em out

Thanks CobKit for replying..

Actually they mess up, I still have the option to replace it (though re-ordering may take some valuable time), but my question is: why should I stress to replace it, if these two options are truly identical?

Thanks.

They're identical in output/quality, but your driver options diminish somewhat with the 72v version. You can only run 2 cobs on your driver if it's 72v, and 4 cobs if they're 36v

If you use the 72v version you should exchange the HLG-185H-C1400B driver for a HLG-185H-C700B driver to achieve the same desired result or exchange the COB's. either you way you will have to exchange something to get the same desired result. COB's cost less to ship.
