R2 OR Q5

[how2]

which is the r2 and q5?

The left is from the Handy Cree Q5-WC
The middle one Aurora Cree R2 (aaa)
The right Ultrafire MCU-C7s Cree Q5-WC

The handy and Aurora look the same.

The ultrafire could be a q5.

Flux bins are impossible to distinguish by looking at the LED.

Sure they are. You just count how many bond wires there are.

Bond wires only break the dichotomy between P4s and Q2s but that's it, from N2, N4, P4, Q2, Q3, Q4, Q5, R2, R4, and maybe R6 the bond wires only made one distinction out of at least 8 comparative LED flux bins

It's called sarcasm. Maybe it was not thick enough.:wave:

edit: The whole point of this thread is obviously off and it just reminded me of the people that used to believe you could tell one bin from another by the bond wires.

I was left to believe that the new R series has 5 bondwires by your post
I went for a wildgoose chase thinking I had missed something, I returned with no luck and made that post hoping whoever would criticize me will reference the link to it:twothumbs

oh well.

get a really good magnifying glass and count how many molecules in the light-emitting layer aren't an InGaN molecule. :nana:

I'll need to borrow NewBie's microscope

Borrow an integrating sphere.

throw em all out and buy R5s?

what? no! give them to me!:twothumbs
some people may not think about P4s in flashlights now, but for fixed lighting they can still stand their ground:thumbsup:
