Name That Emitter!

[donn_]

I try to keep close track of my stuff. I have a text file and a spreadsheet containing everything I know about my Aleph LEs, but one has thus far eluded ID.

It came to me with the following designation; "Cree XR-E (Q4?)"

I'm hopeful someone can ID it with surety.

And its host:

Hard to identify a Cree by looking at it. I've read that the 4 bond wires came into use with the Q2, but later production P4s also had them.
So, it could be a P4 to R2. How's that for narrowing it down.

The R-bins I believe have the silver backing, so it can be narrowed down further to P4-Q5.

Any further is impossible by just looking at it.

I have a couple R-Bin Cree's with the yellow backing, and a R2 with the silver backing. So we're back to P4-R2.

Also I wonder if some people assumed some P4's had 4 bonding wires based on ordering Fenix lights that were quoted as being P4's and seeing 4 bonding wires. Now we hear Fenix maybe using Q2's and Q4's in their non-premium lights that quote P4 specs.

I received a couple of Q5s yesterday that have the silver backing.

I've got some DX Cree dropins advertized as P4 with 4 bond wires.
