Ohms Law ??? Can 62vdc become 145vdc ???

BST · Feb 5, 2016

I have a lpc 150-2450(31~62vdc) if ran parallel string of 4 lines @ 612.5 ma. Do you get 245vdc?

In parallel voltage stays the same, but will also lower due to less overall power to each COB.

Your four parallel strings will measure no more than 62 vdc. BTW if only one diode or wire in a string breaks, the other three strings will carry 816 ma. Can your diodes carry this extra current?

So how many fv can each string handle? I ducked up and ordered a 2450 instead of 1400ma? To little time to much kush. I'm going to have order a cob to match. Any ideas?

Luminous or lumaled I think makes a cob that might work well.

Can you return that 2450? Most everybody are using cobs that are about 36 Vf.
http://www.cob-led.com/ceramic-COB-LED-source-sources-H-LCOB50.html has some cobs that run at 60-68 Vf Fifty Watters.

It cost $40 and to return cost $25 're-stocking fee, so…
Thanks for the help. So it would run 3 Vero 29 @ 800ma?(parallel)

Parallel. I think I'm going to try to get as close to 150w and see what happens to a single

3 vero 29 in parallel = 38.9 Vf (max) x 2.45 Amps = 94.57 watts. Putting more Vero 29 in parallel will not increase the watts to the plants but this will make each cob operate at a lower and more efficient temperature.

Yes but a lpc150-2450 is a cc driver. If a Vero 29 has 39Vf can ya run 3 on it. Lpc150-2450 vdc is 31~62. Does vdc stay the same???

Ohms Law ??? Can 62vdc become 145vdc ???
