2 options, first is adding a COB and heatsink to the center of the light. Just need a 36V COB, yes it will create a hotspot.
Second is to find a 36V strip to go in the center. Bridgelux isnt suitable but there will be others around that can be used.
I would go the strip option myself. You would max out the driver so oar wouldn't change too much. It will be alot cheaper than replacing the drivers and take less time.
What country are you in BTW
Weird issue with meanwell drivers powering samsung strips
I would need to draw it up, it would involve running parallel on 2 of the center strips then back to series for the center strip.
I cant see another way to do it cheap sorry.
It will work ok then though

We have a 36V strip, not sure if it works in your colour scheme,

Forward voltage is too high on those strips for his problem. He cant go over 36V at all.
When I tested yours it was at 39V@ 1.4amps and that was hot. You maybe able to make something custom for him and use 0ohm resistors to bridge 2 of the pads on the mid powers to drop the voltage

Maybe I misread this, he needs 4 in series below 184 volt, even at 40v he will be at 160V and then paralleling those with a second string of 4 he will only be 875ma on the array or 31.5 watts per strip. This assumes the 1750 driver is being usedTEKNIK wrote: ↑Tue Apr 14, 2020 9:52 pmForward voltage is too high on those strips for his problem. He cant go over 36V at all.

Shortly after these lights were built, the buyer decided that they want to use CO2 in all their rooms, and therefore would like even brighter lights. They are willing to pay to upgrade the lights, which could fix my driver selection error in the process.
So far what I have come up with is rewiring the lights to run all 8 strips in parallel powered by a HLG-600H-48B. Then adding 3 additional strips, in series, powered by one of the HLG-320H-C1750B's, I believe this would provide around 1375 PPFD and coast about $285 per light.
Unfortunately there does not seem to be a perfect driver for these strips regardless of if they are wired in series or parallel, in any possible grouping.
Alternatively, I could add an additional HLG-320H-C1750B to each light so that each driver is powering only 2 or 3 strips. I do not know how to tell which approach would provide more PPFD. I believe 8 strips running at 1.56A + 3 strips running at 1.75A could produce more PPFD than 8 total strips running at 1.75A.
I appreciate thoughts on these possible solutions/upgrades.

Will I be able to wire the dimmer leads from both the HLG-320H-C1750B and the HLG-600H-48B to a single 50K potentiometer for dimming?randorson wrote: ↑Wed Apr 15, 2020 3:53 pmShortly after these lights were built, the buyer decided that they want to use CO2 in all their rooms, and therefore would like even brighter lights.
