Whats the difference?

[abrjoh61]

I've decided to get a Nitecore D10... but, I have two options. The Cree XR-E Q5 WC and the Cree R2. What is the difference between the two? Is it just the color? Is one better? Is it worth the 4 dollars more for the R2? Thanks for the help everyone.

R2 is on average 7% brighter than the Q5, as it's the next bin up of the same model LED.

I believe the ramping is slightly tweaked also.

I've been seeing that word a lot and I really haven't found an explanation or definition. So, what is meant by "bin"? Sorry if I'm asking stupid questions.

A bin is a grading scale for the efficacy or tint or Vf of an LED. From the Welcome Mat:

Q: What's "bin"?
A: Bin codes are used to sort LEDs by luminous flux (lumen output at a specified drive level), color, tint, and Vf. For example, a U-bin Lux III will have more output than a T-bin Lux III at a set drive level. Commonly desirable flux bins (at the time of writing) are:
-Lux I: R or S
-Lux III: T or U
-Lux V: W or X
-XR-E: Q2 through R2
-SSC P4: U or V
-Rebel: 0080 or 0100

(puts foot in mouth) ok... I'll have to take a look at that before I ask more questions....

Just wait until you get into tint bins too. That's when the fun really starts :thumbsup:

Thanks mr.snakeman! Flashlights are an entirely new realm to me. Over the past months I've found an interest in EDC items like knives, multi tools, lighters, and flashlights. There is a lot more evolving technology in flashlights though. Thats why I came here. I guess I have to find some time to look over the welcome mat faq's to get fimilar with the technology.
