Info about Quantum boards

We have also some modell of QB LeD if needed

The H's are always top BIN while the B's have variable BIN. Meaning the H's will produce a higher quality light across the whole board. Even if it is only a 3% difference, in 1000 grams 3% is another ounce. Scale that up more and 3% becomes a big increa$e.

Where'd you read the h's are top bin?

I heard it on the swiss forum

Lm301b at 5000k had the highest binning

While lm301h at 5700k and 6500k

The link they used is not working for me but here c&p of it

read that thread again and they only mentioned the hìgher binning at specific color not that the lm301h have an overall better binning

Here's a good article about it.

thx man nice read

If you compare the datasheets of 301b vs 301h you can spot the binning differences. 301b can be the same as 301h, if you get the top bin diodes. All of HLG's older boards with 301b's are top bin, so basically the same as the newer h versions.

Spot the difference

That just shows the flux for all the different possible bins for 301 diodes. In other areas of the datasheets it talks about which bins are used exactly. It's been a while since I compared datasheets myself, but I do remember spotting a difference in terms of which versions (b or h) got which bins. Also that's really only for flux binning. It doesn't even get into the rabbit hole of voltage binning. Steven from HLG talked a bit about this a couple weeks ago on the GML show.

EDIT, here's one example of binning differences between b and h diodes..

Spot the difference

Missing which sheet is which chip?

Missing which sheet is which chip?

Yeah, but the chart is the same, doesn't matter which is which.

Thanks, I'll look into it.

A nice article. thanks.
