Commonly Used LED Emitter Index

[AFAustin]

Craig,

You have been a great help. Thank you.

So, do you think the bit of green around the emitter definitely means it's an XP-G, or is there still some question? Put another way, has there ever been a Rebel with green on the board?

Thanks,

Andrew

Hi Andrew,

Did a bit of research - from a 2009 post of a Rebel 100 Peak it appears there is no green visible in the optic see: http://www.lygte-info.dk/review/Review%20AAA%20UK.html (I believe the green reflection is from something behind the camera as it's visible in the 3rd picture.

So, I'd say XP-G. enjoy the light regardless!

Craig, thanks for going to all that trouble. Yep, that great Eiger Rebel front-on shot is completely "green-less".

Sounds like the jury's verdict is "XP-G".

Thanks again,

Andrew

very useful information for reference in learning LEDs, grateful for that. I've got a question here that when making the light for Diving, is there any special request for the emitter？Since diving is different from the common situation, the shape design and materials for light calls for high quality and good water resistance, but for the LED emitter, any special request? Any suggestion will be appreciated. Thanks.

tint might come into question for underwater use, but I'm not sure what you'd need!

Does anyone have info on tight spot reflectors that can be used with SST-90 emitters ? One of my first projects is going to be based on that emitter. I need some examples of reflectors so I can machine a housing to hold the LED, reflector, window, and incorporate a heat sink. I plan to machine the housing/ heat sink from a chunk of copper. I am hoping to have a part that is functional, ( Thermodynamically sound ) and attractive.

I found that the Luxeon Rebel in Maglites have better tint than Cree chips...

Some of my Cree chips (XRE, XPG and XML) are greenish, and some are blueish its hard to find one with good tint, but both the XL50 and the AA have a near perfect pure white tint.

sorry out of topic a lill
Hi,are you the same wintermute that have been lost & found

Hey Nanotech - nice flashlight - it must be the one all my taiwanese buddies decided to knock off and sell me - I have several different versions of it.

Thanks so much for putting all this info into one spot! very well done.

This thread is a nice thread. Great posts are shared in it. I think it will more helpfull to people.

Hi! new to CF... I want all of these LEDs!

[okenobi]

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...?

There is a little more info at Flashlight Wiki, but not everything like viewing angle, Vf, etc.:

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.

This looks like it needs updating pretty badly lol

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.

Hopefully the OP is still getting email updates.

Dear OP, please update this thread for us helpless mortals.

Thanks and congrats for the post! It was very informative!
