I haven't tried it but I agree that it should fit. As far as I know all of the clips are interchangeable with the only real limiting factor being the length . . . for example, the E2DLU clip would look a little funny on an E1E :laughing:

I've just ordered an E2Dl Ultra from battery junction & they've sent me an e-mail to tell me it's on order from Surefire,i was wondering if anyone knows how long it takes for Surefire to deliver an E2Dl Ultra to a supplier once it's been ordered.
After some use in the dark outside I am very pleased with the tint and nearly perfect combination of throw and spill. Surefire hit a homerun with this one!
Also, the 5 Lumen mode is great for indoor/outdoor use providing ample light and extended runtime.

I've been using mine, and comparing it to my old 200 lumen version for about three weeks now.
While I like the high mode on the new light a lot, I find the low mode to be a little lacking. Due to the more tightly focused beam of the old 200 lumen version, the low mode was great for up close, as well as medium distance use. On the new light, the low mode is good for short distance only. I feel like I am constantly being forced to choose between either not enough light, or way too much. I feel that for me, the new light would be much better with a 15 lumen low, rather than 5. For this reason, I'll probably continue to use the old light more...

Hi, I got my new E2DL ultra last week and tried with Sanyo (2100mah) and Efest (2200mah) 16650 batteries (charged 4.2v) in it. It works OK (but not good).
Most of times after the 1st click it strobe once and then have about 30-40% of the high output level (I think that's quite enough for normally daily use), click again it will be the low level. And after severl clicks (may be just one or two maybe many), it will have high level output (which is not as bright as use two cr123a, but still quite bright).
Then after 6 hours (quite long), the output still obviously brighter then the low output level (I don't know how many lums.)
So by conclusion, if you use the 16650 rechargeable battery (3.7/4.3v) in the E2DL ultra,
the good thing is: 1 You got three levels out put,
2 You got quite long run time.
but the bad thing is: 1 You don't know how many times you need to click to get the highest level, (normally I think the lower the voltage of the battery, the more times you may need to try. If it is 4.2v sometimes it comes at 1st click)
2 the highest level is not as bright as two cr123a.
Cheers:)

You'd get better results with AW RCR123s 3.7v 750 mAh.

Thanks Novan, I'm thinking about that, but there are two concerns:
1. I don't know does it really safe to use two 3.7v AWRCR123s. I saw Grizzman and seattlite's post, but it seems that their tests are just a few minutes and the temperature of the head becomes really high. So it can not prove two 3.7v RCR123s won't have any bad effects on the light (such as shorten the life of the LED).
2. I guess 2 rcr123s (2x 750mah) will have much shorter run time than 1 16650 (2100-2200mah), because they are higher on output but lower on the mah.
Actually what I'm really concerning is the first one. But the surefire's own LFP 123A battery can be charged to 4.2v (although normally 3.2/3.7v), so maybe that means it is really safe to use 3.7v rcr123 (16340)s?
I've been using the Ultra exclusively with RCR123s for over three months, so I guess it's time for a run time test.
For the test, I'm using freshly charged AW RCR123s.
First....temperature. I held onto the body of the light for the entire test, and it never got beyond warm. I was able to comfortably hold onto the head also.
The head reached 112 degrees after 15 minutes, and remained at that temp for the remainder of the test.
I didn't measure the lux during the test, but it didn't dim appreciably.
The light shut off after 49 minutes.
While a sample size of 1 is far from conclusive, I'm now comfortable running mine on RCRs for as long as the cells last.
After about 15 minutes of recovery, one cell measured 3.208 volts and the other one measured 3.260 volts, at rest without load.

Thanks a lot! That's very useful information!
BTW, do you know the temp when the ultra use two surefire not chargeable cr123a?

I've put a couple mostly new Surefire CR123s into the Ultra.
1 minute - 93 degrees
5 minutes - 110 degrees
10 minutes - 111 degrees
15 minutes - 111.5 degrees
20 minutes - 112.5 degrees
25 minutes - 112 degrees
These results are virtually identical to those from RCR123s.

Thanks a lot Grizzman, I think these results really proves that use two rcr123s (3.7/4.2v)
in e2dl ultra will not shorten the life of led.:thumbsup:

Has qnyone heard or seen anything about a single stage E2DL Ultra?
I have one of the older E2DL's that are single stage only, it just gives the maximum level when you press the switch. No low-level light.
I have been using this as a handheld weapon light but I would want to update it.

I don't recall reading about a single stage E2DL light, but Surefire does offer the single stage KX2C head.
Some people here, myself included, have been hoping that they'd release a KX2C Ultra, but I haven't heard anything official about it yet.

The EB2T has a single-stage head if you use it with a standard clicky.

Ok, thanks for the replies guys!
I think i shall look into that EB2T... :)

Snagged one. I'm happy.
Thinking about buying one of the Vital Gear FB2 or FB3 bodies for this thing.
I'm assuming it'll happily take 3xCR123 since it seems the consensus is that it'll take 2xRCR (8.4v). Would runtime be improved enough to justify this? Surefire's buck circuits used to be wicked efficient... are the new ones as well?
I bought one when they first came out. I also have the old 200 lumen version. First, I think I lost the tint lottery. I see a subtle greenish-yellow, how do I know? , because of my white-wall hunting. Not exactly quantitative. Second, the new head is significantly larger than the old E2D. There is more spill in the ultra and more than double the lumens. The E2D ultra requires a 2-cell setup for basic operation. I ran the old E2D on single cells with no problem. I tried running the E2D Ultra on a fivemega E-Head-C-Tail with a fresh 18650 4000mah, I got about 2 minutes of good use, before the output dropped. I used several tails designed for high-amps, even a fetie switch. The E2D ultra is not as dependable or versatile as the older model.
