Loads of great info in this thread, but I'm trying to find something simpler if possible. Do we have a list anywhere up to and including the the XP-G2 with just a brief explanation of the characteristics/performance of each LED and perhaps a way to compare them?

I've read all of this and I still feel unable to know what LED is in my current light and how it would compare to the currently available options. Am I missing something obvious...?

That was very helpful, as I am trying to get a flashlight with the most recent generation of led. I saw an ad recently for a gen 2 led. What is the most recent generation of led to look for? Thank you.

Of course I am no expert, but going through the cree site it looks like the XM-L2 is their latest and highest performing single die LED. Not sure if I am reading it right, but it appears to be 1198 lumen at just 3A. I could be wrong though.

Who is up for that challenge? jcw122, were you volunteering? (I don't have the time due to other commitments, but always found this an interesting thread)

No I'm looking to start another list-reference type thread soon for warm lights, so I'm hoping to be focusing on that.

This is a great resource.
Thanks Craig and to all those that have provided updated info and photos ;).

I have a question. Is this one of those non-listed no-name LED's you have spoke of?
It has four bonding wires, but the phosphrus is so thick and the die sits so deep, I can't tell. I was able to get an approximate die measurement using the optical software used to take the photos, and it appears to be about ~1mm square. It is a low powered LED, purchased installed in a flashlight only 3 years ago :thinking:

Thanks
GL
