Hey everyone,

I was all excited to bring another QB304 board online tonight and it did not work!

I've ordered 3000K, 3500K and 4000K boards recently...all QB304's. The 3500K's were the most recent purchase and the boards did not look quite the same. I didnt think much of it until I connected a 3500K to a 4000K in series using the HLG-240H-C2100A driver.

Here are some pictures to show the differences in how the 3500K's look compared to the 3000K and 4000K boards:

3000K and 4000K boards all have this sticker to indicate the spectrum.

This is what the 3500K's look like

Any thoughts?

Edit and Follow-Up:
Running (1) 4000K on this driver is pulling ~114 watts at the stock setting. I have not messed with the dimming. I just put my killowatt on a single 3500K and its pulling like ~255 watts. WTF.

If it's from a different batch the voltage could be different they used to write the voltage on the board with sharpie haha I have a few that I have to run on individual drivers because they don't match.

Unless they changed the markings, that QB 304 looks suspicious to me. Send an email and pics of the full board to HLG, and if it is theirs, they'll take care of it pronto, don't worry. If its not they need to know where you got it. I may very well be wrong but talk to HLG they'll sort it out

What are guys hanging you lights with. I bought ratchet hangers 4*. I have dual boards on each heatsink but want to wire two sets together but be able to raise and lower the two sets independently because I'm under a stairwell na downward slope.

I originally planned on tieing the to boards together with angle aluminum but I'm thinking having flexibility would better. Trying to avoid having to get 4 more ratchets.

The 3000k & 4000k boards with square diodes & Samsung look like QB288V2 LM301B

rectangular diodes are V1 LM561C

I already emailed HLG but since it's after hours on a Friday and Monday is a holiday, I don't expect a response for like 4 days...so I came to you...the experts.
WTF...now I don't even know what I have and I'm basing all of my plans around this.

I bought everything directly from https://horticulturelightinggroup.com
I didn't use Amazon or any other vendor.

These purchases were all within the last 30 days or so, roughly. I have 6 boards in my possession with 2 more in the mail.

Those are the old batch of boards. The 3000k and 4000k have those stickers because samsung produces their boards now pretty sure.
The old ones had the CCT marked on the bottom

The reason it didnt work is you need to connect them in parallel. That driver will not hold 2 304 boards in series.. the CC region is 59-119 and the vf of the 304 is like 100+

When you add another 304 board, you put it over its constant current region. Try connecting them in parallel and see if it works.
That driver will do 2 304 boards in parallel. Not series. Check again

I've got (2) 4000K's running in Series. I've got a 4000K and a 3000K running in series and it's perfect. I'm not an expert here, so don't that that as me getting defensive, but I'm currently doing it. Each board is drawing 113/114 watts at around 0.9x amps per.

You have 2 304 boards running on an hlg-240h-c2100? In series?

Yea they arent 304's, which is why you are able to have them in series on that driver
Which is the reason you cant add anything with the 304 to that driver.
The 3 pics show a qb 288 v2 3000k, an 304, and a qb 288 v2 at 4000k
