Hi everyone,
Noob here, tried searching the forum without much luck. I've ordered 3 qb 288 v2. I plan to run in a series with a hlg 320h c1750a. I did the math when I made my order. Looking at it now something seems off. Did I mess up?

Thanks,

The set up will probably max out at 270watts depends how much current the driver will allow, the A type drivers will normally do a little more than the specs suggest.

An HLG-320H-C2100A or B would be a better choice.

Thanks for the reply. I will amend my order.

So why does this pull lower wattage. Just curious, I saw timber grow lights offer 3 288 with the 1750. I've already changed my order as suggested. Just curious. I'm trying to learn.

Hmmm, that 2100 will only do 152V; I don’t think it’ll be able to run 3 actually.

According to hlg's website, the qb288 v2 pulls 48.96v @ 2100mA. Is there a reason that driver won't run 3? That's only 147v. Maybe you are thinking qb288 v1?

It also says to add a tolerance of 1V for each board for matching. That being said, that’d still only be 150V so you guys are right - it should work.

Hmm. I didn't see that. Nice

Accordinf to the data sheet for the 1750 it will go to 183v. Is this wrong. I'm trying to understand why it will only pull 270 watts. What am I missing?

Nm. I see what i missed. Thanks door the help
