I guess I could compare the cost of 240 bridgelux strips (or 480 if they are 2 footers) to the cost of 30 Mean Well
HLG-600H-48B ($5,545.27).

And I have to consider the labor difference of scraping off all the thermal tape and applying new strips vs replacing all the drivers and wiring all the lights in parallel.

But if the Bridelux strips are not going to produce at least as much PPFD as the f-series, it's not an option. I cant expect my customer to downgrade because I bought the wrong parts.

Is there any market at all for used Mean Well drivers? I have no idea what I will do with (30) HLG-320-1750B's.

I'm pretty sure there is a classifieds section on this forum.
Have you already built all the lights? You maybe able to return them from where you got them and exchange them

Maybe I can power a set of 3 strips each with the current 1750's and then add a driver to power the remaining 2 strips on each light?

A pair of these strips would require 49 vdc /3.5 -3.6A in parallel or 98 vdc /1.7 - 1.8A in series. Not sure if any driver exist for those specs?

Yes, already built and installed. I only noticed the problem because I was taking some measurements while thinking about how to build brighter versions for CO2 enhanced rooms. I noticed I was only seeing 550-600 ppfd instead of around 900 like the lights powered by HLG-320-1400B's produce.

Can you take a picture of your light just work I can get an idea of how you have it set up.
Its 2 drivers per light right?

Yes it is 2 drivers per light. Each driver powering 4 F-series strips. They are very similar to a doubled version of these,

Is it a Tslot design so you can move the strips to the sides easily?
A few reasons why I wanted to look at the specific light you have

The space between the middle two strips is 6". The spacing is asymmetrical, decreasing towards the outside of the light.

No. Only my first few lights were that way. It added too much cost to the lights, and I could not see any benefit. I'll post a pic.
