Output of Surefire E1e & E2e

[JerryM]

I want something comparable to those Surefires at less cost. I cannot seem to find what the outpus of the two are.
Can someone provide the information?

Today I see LED lights with outputs of 100 - 300 lumens and more. I assume that LED lights do not have the range (throw?) of incandescent lights. Is this correct or is it just a function of the reflector?
Is there any advantage of incandescent lights now?
Thanks for the help,
Jerry

E1e with the MN01 = 15 Lumens for 1.5 hours
E2e with the MN03 (Stock) = 60 Lumens for 1.15 hours
E2e with the MN02 = 25 Lumens for 2.5 hours

I have these memorized...is that sad or what??? The 15 lumens of the E1e is more than enough to navigate with...I prefer to use my E2e w/ MN02 due to the extra long (incan wise) runtime.

The main advantage of incandescents right now is color rendering, since they will have a CRI of very nearly 100. "High CRI" LEDs will usually rate 85-93 (depending on the specific emitter), and typical LEDs may be significantly lower than that.

Incandescent lamps will also usually have a warmer (more yellow) tint than most LEDs, but there has recently been much more availability of LEDs in neutral and warm tints. When they were first released, most had a very cool (blue or even purplish) tint.

The throw of a light is more complex, however. The surface brightness, size of source, and optical factors (shape and nature of reflector or optic) generally have a greater impact on throw than the "type" of light produced.

There are *many* threads on each of these topics here with voluminous information, if you are interested in further details, but that's a quick and simple overview for you :)

Thank you both for the help. I appreciate the response.

Added: When I was hooked on flashlights I bought a couple of aluminum tubes that Surefire heads would fit on. One is a 2AA that has an E2e head on it, although it has not markings on it, and the other is for one CR123 battery. It has a KL1 head on it. Not sure what the output is, but it is not a high output.
Actually the "tubes" are not bad although a tail switch would be nice.

This post demands pictures! :D

No definite relationship
Incan and LED can always out throw each other depends on optics

All incandescents have CRI of 100 because physical theory says so (they're blackbody radiators). However in the real world incandescents may be totally inappropriate for colour rendering and matching, since they kill the blue part of spectrum (esp. those with CCT's in the lower range). AFAIK, CRI comparison between two light sources may be performed only if they're of equal color temperature (CCT). Otherwise it's like comparing apples and oranges.
