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.

What cell were you using? I don't think 18650's came with 4000 mAh yet. I ran my E2DL Ultra with an AW 18650 3400 mAh in a FM E-Head C-Tail body with a Malkoff C Tailcap.

If you look at the review at led-resource.com the graph did indicate that the output will drop to 60% after a few mins.
 
Oh, I've got no complaints only observation. Some people like warm, some like cool, some hate TIR, some love it. Does anyone think that a "burn in" might change the tint ? I did notice it slightly on the 200lm version.

Has qnyone heard or seen anything about a single stage E2DL Ultra?

I think that these were manufactured by mistake during the early days of the E2DL (2008 or so). Surefire never labeled or advertised a single-level E2DL, but some people did prefer that version.

Anyone thinking about buying themselves an E2D LED Defender Ultra for Christmas needs to head on over to Amazon.com or visit this post in the CPF Marketplace.

$139.99 + Free shipping (US) is pretty tough to beat!

Amazon price back up but B&H still has cheap price and free shipping.
 
I got one from the amazon sale and I've been playing with it for a while.
It is built and detailed very nice like any other high end surefire product, but using it outdoors has made me realize how much dimmer it is than any of my custom 2 cell lights (DD SST90, MTG2).


The E2DLU optic produces a tight beam and hotspot, but not the huge volume of light that big emitters do. Not exactly a fair comparison, maybe just spoiled now and need my fix somewhere else.
 
I haven't had a chance to fully read through this thread yet. But would like to ask if anyone has seen any possible issues or glitches or problems with this light yet, or at all?

One particular being, after a period of non-usage, i.e. storage of the light for a week or more while a different is used, when you go back to use the light, has anyone seen any issues with the high output, on perfectly fine batteries, not actually put out at its highest, or take a minute to ramp up to the output its supposed to put out? Almost like the high, when turned on, isn't any brighter than the low. Also when it turns on there's a bit of a flicker to the light and after a few times turned on that goes away?

Should I be concerned and consider sending to surefire?


Does anyone care??

Buller???

I haven't experienced any issues like you described but it sounds similar to the EB1's behavior when used with a freshly charged LFP123 battery. What type of cells are you using?

For the sake of troubleshooting, you might try a different set of CR123 primary batteries (if you haven't already) and see if the problem persists.
 
Just using standard surefire batts. When it did that I changed cells, thinking it was a dying cell but it did it again. So I changed back and after a "warm up" period of sorts its running ok. Just makes me wonder if the batteries were cold or what not or if there was a need for the light to "wake up" after a week or so of non-usage.. Just seems to be the only light that I have seen that happen in.

The exactly same thing happens to me. But if I use two 4.2v 16340s, then it will be fine. So I guess maybe because the light need higher voltage than other 6v lights.

Sounds like the same encounter I had experienced. It happened to me quite frequently whenever I left the light alone for a couple of weeks, but then I thought it could be due to the batteries being partially depleted.
 
I use mine rarely, and have never experienced this. I'd say something's definitely not right, and Surefire should happily take care of the issue.
 
The E2DLU has a greenish beam compared to the E1DL correct? I just got both and color temp is drastic. E1DL being much cooler with a slightly wider beam.

Also, anyone have flickering with the E1DL as the batteries are at about 80% spent? I still have high / low mode but get slight flickering on both.

Im coming from a Fury so as soon as I loose high mode I swap cells, no flickering.

Really appreciate some input. Thank you.:party:
 
I don't have an E1DL, but I do have LX2, E2DL, and 500 lumen KE2C head.

The only one of the bunch that doesn't have a pleasant slightly cool tint is the Ultra....and it's seriously green.

The E1DL should not flicker at all, so something seems wrong with it, or the cells.
 
Thanks Grizz.

EDIT:

I continued the E1DL flicker question in the E1DL thread where it belongs.

It slaughtered my LX2's reading at one meter of 9.30 Klux by delivering 18.36 Klux. Both lights were run off fresh CR123 cells.

I finally got around to testing my Ultra with fully charged AW RCR123s. Hot off the charger (resting), one measured 4.184 volts and the other one gave 4.188 volts.

I immediately turned it on and took a 1 meter lux measurement of 18,870 lux with my Extech EasyView 30 meter. After five minutes, the light was still happily throwing photons and measured 14,990 lux. After allowing the head to cool to a temp of 85 degrees, and the cells to slightly recover, I took another lux measurement. It did 18,780 lux.

I found some info for ya. Did you read through the thread?, It's only 12 pages. :poke:

If you'd like fresh readings, I can do that. Work has been less than fun today, so some light action this evening may perk me up.
 
New or previously measured lux would be equally great. I did a search but got no specific measurements. I have heard SF claims 16000 cd but I couldn't find that on their website.

Is this model available with the 2 level tactical switch like the eb1 tactical or old lx2?

I heard that the P2X is a bit more cool white (Blue) is that true? I hope so! I just bought it because the yellow of the G2X really bothered me
 
Just read all 12 pages. Good read. Thanks

Will probably end up obtaining one at some point. But the EB1 has me so thrilled right now, and are going for less than $100 for the 200 lumen version... but 18k sounds pretty dawg gone inviting.... it'll just be a matter of time.
