That makes a lot of sense! P,Q,R....I bet theres S and T too (or will be) =p
thanks for the explanation. Now, will an R2 get hotter or drain battery more quickly than a P4? Or is that were the "high efficiency" comes in and it has the same battery usage and heat generation as an emitter that produces less light? Is it basically always better to choose a higher "tier" die?
thanks!
Generally speaking, you're correct. The higher the bin, the more light the LED can output for the same amount of current.
Also, there are already S and T bin emitters. The XP-G is up to S3, and the XM-L is at T6.
In your first post you mentioned W2. That's actually a tint code, and not related to efficiency. There's a lot of codes out there, and it's easy to get confused
Just don't fall into the trap that a lot of people here do. You'll see a lot of folks talk about a "Cree R2". That does not define what sort of emitter it is. Cree make the XR-E, XP-E and the XP-G in the R2 bin. Defining which emitter is important, especially if you're buying or selling a light.
