High Performance Group - CXB3590

We'd like to focus on the topic of „High Performance Group – CXB3590 Bin“. As many of you have noticed, every chip has different bins. As you can see in the picture below, the CXB3590 has more than 8 different bins according to which all COBs are sorted independently of their spectrum. The deciding factor in that regard is solely the „Minimum Luminous Flux“.

Even within one and the same production batch the quality levels of the produced LED chips are not uniform.


If we look at a production batch of 100.000 CXB 3590, color spectrum 3500k, we can observe the following distribution of quality levels:


5.000 20.000 40.000 30.000 5.000

This results in every production batch containing better and worse binnings by default. Because High Performance Group BINS can't be deliberately produced, CREE has not included them in their standard product catalogue. You can find the performance groups in the data sheet on page 14, lower section.

The regular CXB3590 series is grouped according to different quality levels. As you can see in the chart, the top-bin is the CD version. However, occasionally an exceptionally good batch will be produced and in that case a DB version's output can beat the regular series' top-bin by 1000 lumen (10%).

So what does that mean for you?

From time to time we can offer a limited supply of High Performance Group chips. We have, in fact, some in store right now. In case you're interested in getting your hands on these rare bins check out our online shop, category LED-CHIPS. If we have them in stock they will be labelled with "TIPP".

Here is a link to the CREE CXB 3590 3500k DB BIN.

Please understand that we can not order these bins on demand and that we can only offer what we have in stock. For logistic reasons they are available only as individual sales.
