There has been a report in another board that some E2DL's have the following issue: Any slight shock from the rear (like a rap on one of the rear crenelations by a knuckle, or striking a hard surface with it) drops the light from constant on high beam to low beam. When the light was mounted on a carbine (LaRue mount) "the shock of the bolt carrier coming forward knocked the light to low power." I'm going to test my E2DL tonight.

My E2DL will do exactly that. When I dropped it onto my carpet it switched to low. That was the first time I noticed it. I can get it to switch levels by striking the tail of the light.
I don't want to send it in though. I have one of the few LOW first, HIGH second bezels and like it that way. I just don't want it to switch levels by an accidental knock or drop.
I will try a thin battery spacer at some point to see if that helps.
I'm interested to see if this is reported in all E2DL's or just some.

First the LF5XT and now the E2DL? I know competitors want to copy SureFire designs but this is a bit much.

In theory, all e-series multimode lights should have this problem. The single cell lights maybe not, because one cell is lighter and has less inertia.
The c-series lights suspend the cells between springs, so they can not lose contact.

Why are the E2DL's being used mounted on weapon?
SureFire offer their M600C and X300 WeaponLights.
They also offer the KX2C bezel for those who want to update their existing ScoutLights or want to mount an E-Series flashlight on a firearm.
Don't use a dual output handheld flashlight such as the E2DL, E1B, E2L/E1L as a WeaponLight.
Simple.

I Agree....There is no reason a 2-level light (that uses clicks to change levels) should be used as a weaponlight. If you need a light on a weapon it should be at a tactical level (at least 60-80 lumen) If you need low level nav lights buy a specified light such as the M900 series with the 5mm low level LEDs.
To the OP.... the KX2C would be a better choice

This is another reason why I hate those electronically switched light levels. My Fenix L2D will do that too when it's knocked on the tailcap. As other explained, the batteries disconnect for a few milliseconds and the head interpret that as a level switching request. I love my single level E2DL!
I agree wholeheartedly -- the E2DL is clearly useless and potentially dangerous as a weapon light.
I do believe, however, that a multimode handheld light such as the Gladius is fine for weaponlight usage.

Makes me even more glad that I got a single-stage (high only) E2DL

There are some User Interfaces (UI's) that whilst not completely KISS, can be used in conjunction with a firearm, or mounted on a firearm.
Ken's Gladius UI and SureFire's two-stage push button pressure switch are examples and there are likely others.
I believe central to KISS UI's is the ability to "mash down" (as SureFire puts it) and activate high output. Another key ability is to deactivate the light easily and quickly. A momentary pressure switch is perhaps the most effective way of ensuring the light isn't activated when you don't want it to be. A single actuation, for example of a latched or electronical simulated 'clickie' are two of the main methods.

I agree with others here....nothing advertised describes the E2DL as
having an anti-shock head or body.
Just like in the catalog, carry it in your girlie purse and don't drop it or
mount it on your weapon.

Ditto. I reported the problem on this board a few days ago regarding my E1B head on my Vital Gear 1 cell body. I can get the light to change with a quick shake. I just tried my E2DL head on my Vital Gear 2 cell body and same thing. I agree it is circuit interruption causing the change. I can't get my E2DL body to do it with a quick shake, but can with a hit on the light.
I've decided this is a "feature". Something like: "Features Surefire's new 'Shaker Head', which gives the user the ability to change light modes with a shake of 30 mph or greater. Also works if the user finds it necessary to beat him/herself on the head with the light"....8-}
Heh heh... this switching-by-shaking could catch on as a nice way to change levels.
However, I just tried my E2DL and could not get it to change levels by shaking as hard as possible (til my elbow hurt) or by banging the light on a hard wooden surface. I could get it to change by dropping directly on its rear but I don't see this as a problem for 99.9% of users. If you drop the light at a critical moment (and it just happens to land directly on the front or rear bezels) then changing levels is the least of your problems.
There might be a problem, however, if striking someone with the bezel puts the light on low when a high-beam is needed. Then the famous "temporarily blind your opponent" claim of surefires becomes moot and you just have to hope the bezel has done its job on their head

Nothing describes the LiteFlux LF5XT as such either, but it doesn't stop people from complaining. Why would a SureFire thread be any different? :naughty:

I really like the Surefire two-stage for the exact reasons you have set forth here -- I think the switching concept on my A2s is marvelous, practical, natural -- extremely well thought out.
I think everyone who has mention the battery loss of contact here is correct. Just tried mine. It changes mode as described, and changes particularly easy when the light is held (big word here folks) Head up orthogonal to a surface and accelerated tail first into the surface -- this only takes a very light tap for the mode to change. Tap once it goes from hi to low, tap again back to high, tap again back to low, etc. Tellingly, doing this with the light moving headfirst into the surface does not change the mode however. Thus, it really does seem like an issue of the batteries losing contact with the contact at the base (although I suppose the disconnect could also occur where the batteries contact one another) -- if the head had a spring contact to keep the batteries in contact perhaps the momentary disconnection would not occur and the mode would not toggle.
I have never taken my E2Ds or my new E2DL Shakerlight (credit to PsuedoFed) too seriously as strike weapons. I like the E2DL mainly for the high output and because I know from many years experience with my E2Ds that the rim on the tailcap is enough protection against inadvertent activation, that I can carry the light in my pocket without having to lock it out without any fear of it inadvertently draining. And the E2D and E2DL I carry are at any rate, backups to my Typhoon 2 anyway. So I am not worried about a mode change while bashing something.
