SUREFIRE EDCL-2T

[F89]

It's the U.I. that is the real draw for this light though. I do love my MDC tir lights.

Yeah I'd have to agree with that, the UI is great.
I'm a bit critical of surefire as much as I love them. I'm more interested in mods there of.
I think it was Jose that posted the Super Scouts on LX2 bodies, for a stock light albeit a leggo. That's a much more interesting light to me.

I'll give it that it lights up a decent area for the amount of throw it has but I don't think there's anything special here.
Runtime will be pretty ordinary on 16650 I imagine. The Malkoff E2 Super would be a superior alternative in my opinion.

Yes i agree e2 supers are still better.

Well...i am glad to see the low is more then 5 lumens. The beam pattern looks good on high as Well. I am kinda excited again. I guess.

3.5 amps is far out of spec for a 123 size cell. That's concerning.

It would be nice for others to chime in on the high amp draw although my understanding some of Surefire's other lights have drawn that level of amps.

Are these lights a 2 cell variety (on CR123 primaries)?
Either way, it's not a reasonable amount of current for 2x CR123 and that's why there's comments about it being concerning. I personally wouldn't happily use this light as is.
Surefire wants to keep the primary CR123 platform (not necessarily a bad thing) but they also want to be seen to be with the times as far as output goes and have, in my opinion, come up with a poor design by trying to combine the primary platform with greater amps.
It kind of goes against their reliability theme really but on that note there's nothing particularly impressive or extra tough about the electronics that goes inside them anyway from what I've seen.
I reckon they need some of the electronics gurus from the forums (or someone... anyone?) working for them to create a product worthy of it's price point and reputation.

Wasn't the M6 fed by 2 banks of 3xCR123 so the 4.9A is really shared by two 9v banks?

Yes, I believe that the SF MB20 carrier was wired 3S2P

How about beam shot between E2Dl Ultra & EDCL-2T
(I have Surefire E2DL Ultra 500 Lumen)

I could be wrong but I thought the E2DL Ultra uses the same head as the EB2 head but with the pointy bits.

3.5 amps seems REALLY high, looking at some past threads seems like the consensus has been 2C is about the limit for primary lithium, which in the case of 1400mah CR123s mean somewhere just under 3 amps, I would imagine the output would drop like a rock after the first few seconds. I guess whenever I get mine I will get some 16650s for ongoing usage.

Looking at the specs for Panasonic 123's (all U.S. 123 cells are made by Panasonic)...Max constant discharge is 1500MAH constant, 3500MAH Pulse, with pulse being described as: "Current value for obtaining 1.0V cell voltage when pulse is applied for 15 seconds at 50% discharge depth at 23 degrees C."

 

[270winchester]

I am now curious that if there is indeed a sharp drop after turn on, which I don't doubt would happen with primary cells, would the same behavior be repeated with a li-ion 16650 cell that could take the current draw for a longer time, or would thermal protection then be the limiting factor that triggers throttling back the power?:shrug:

The difference between the eb2/e2d ultra 500-600lumen models is really hard to tell. They have the same beam pattern (except the eb2 doesnt have the petals casted on the edge of the spill from the crenulations). That particular model eb2 i was using was the 600lumen version, visually i cant see a difference in brightness but my meter reads if i can remember like 16-17kcd for a 500 lumen head

Sorry just realized it's lower on 2x123 vs 2x16340 and even lower on 16650. So it seems to be an un regulated low like malkoffs and elzettas. Id say yeah its a 5 lumen low on 2x123 but more diffused vs the eb2. Ill get some low beam shots later tonight with the 3 different battery configurations. Dang thats a bummer imo

 

[Up All Night]

Thanks for the pics and numbers J M. Quite the discrepancy with candela. More confounding is the package has it rated at 450 meters ansi, which equates to 50kcd!
What's going on SureFire!?!? :hairpull:

 

[Jose Marin]

Yeah i would love 2 see someone else's kcd measurement just to verify even though im pretty confident in mine.

Ok...im back to not being excited again. However i bought it knowing it was 5 so I can't complain really. Thanks for all your info.

When you have a moment, can you post your exact test protocol? Thanks!

Will the head of the EDCL-2T thread on the E2DL body?

What happens if the EDCL-2T is activated by a click switch?
