E-2 60 Lumens = ???? CP

[**DONOTDELETE**]

If the E-2 output is 60 lumens (per SureFire) then what is the candlepower.

Is there an easy calculation to convert Lumens to CP???

Thx CPF'ers

OH MY...another Candlepower/Lumen question. From what i've gathered from other posts on the same subject, you can't directly compare the two. This is a TRUE apples and oranges type of comparison. I beleive candlepower measurements involve the distance of observation, and the beam angle of the hotspot. And lumens has to do something with general light output??? i dunno...something like that - it's complicated.

Anyway...you can have a 60 lumen light output any kind of candlepower depending on the characteristics of it's beam angle i believe. If you have a super tight beam...like a pelican flashlight...then yer talking high candlepower ratings.

The Streamlight Scorpion, from my observations, they are almost the same brightness and beam size/quality. They rate the scorpion at 3500 candlepower. I hope that comparison helps.

Thanks LEDAgent for speedy reply.

I've seen in several sources that the 6P produces 17,000 cp and the 9P producing 19,000 cp. So I guess the E2 is around 16,000 cp. Galls Inc. sells the 6P/9P and lists it as such. The scorpion bites. The rubber keeps moving around on me.

Candlepower or better called candela is lumens/steradian of solid angle. A flashlight can have enormously high candlepower if the beam is narrow or ideally parallel. Thus a flashlight with a lamp emitting only 1 lumens can have infinite candlepower if the beam angle is zero (parallel light). This is a classic game of specsmanship. The only true test is lumens on the target and that takes a shine off to prove.

Sure, but CP is a much better salesman than lumens. If 500 lumens are so bright, imagine what 1,000,000 CP (WOW!!!! Look at all those zeros!!) must be like!!
