Adding more for efficiency?

drcucumber · Jun 7, 2020

I have a LED board like this with a non dimmable 150w driver. Each board is 85w.

Can i simply add two more boards, keeping the same driver? Sharing 150w between 4 boards instead of 2?

And if so, it is there a noticeable efficiency increase?

What driver are you using?
By the wiring it looks like a c.c driver.

it wasn't actually my light. Just a similar one. My light is a ISH170. Which is i think is basically the same as the newer ish150v.
The two boards are ISH150. Slightly bigger than the ISH120.

My driver is
ELG-150-C2100-3Y

You can. But you'd need to wire it as 2 parallel circuits of 2 in series.

before I do this, is it actually a good idea?

That depends, what is your goal? It will increase efficiency.

Its a good idea if you want to improve light spread and efficiency but not total wattage or area of canopy though it will increase total light output to a degree.

It will also allow you to lower your light considerably closer to plants.

I think it should be useless in most scenarios.
Efficiency increases about 10%.
Buying 2 boards and another driver gives you the same efficiency but twice the light. better deal in most cases.

If you double up on boards you will be able to cover a little bit more cannopy, but not the double.
