Warning: pic heavy, as usual.
The ED11 is a greatly revised version of the Lumintop ED10 that I reviewed some time ago. Basically a whole new light with a new user interface and clicky switch, the ED11 remains a relatively compact option in the 1xCR123A/RCR space. Let's see how it compares to some others I've reviewed recently …

The ED11 is relatively compact for a 1xCR123A light with a clicky switch. While not as petite as the Eagletac D25C, it is in a similar class to the Foursevens QTLC or Sunwayman V11R (although slightly thinner). It is certainly larger than the thin-walled ED10 twisty light that preceded it.
The overall build is fairly solid, with a good weight for the size. The ED11 features black anodizing (matte finish), with clear white labels (not overly bright). Although it does have a considerable amount of knurling on the head and body, it is not very aggressive. Especially with the pocket clip attached, I'd say grip is good.
On that note, the pocket clip is of the typical clip-on style - but it seems to hold onto the light fairly securely. It does not seem to be reversible though, so you are limited to bezel-down carry only.
The tailcap features a reverse-clicky tail switch (i.e., click and release for the light to come on). Reverse clickies are typically low profile, facilitating tailstanding. There is a stylish shiny tailcap retaining ring at the base of the boot cover.
Tailstanding is pretty good on my sample, although there does seem to be a slight instability due to the raised tailcap regions not being very wide. On the plus side, you can easily activate the switch with a thumb or finger, depending on how you plan to carry the light. There are split-ring/lanyard attachment holes on the side of the raised tail cap regions.
Screw threads are standard triangular cut, and are in good shape on my sample. They are not anodized for lock-out, however, given how the interface works (scroll down for an explanation).
The light has a slightly scalloped bezel, with a relatively smooth reflector. Although smooth, the reflector doesn't seem as shiny as most (i.e., perhaps a very fine texturing). It is also slightly deeper than most lights in this class (but that probably won't enhance throw too much, given its overall size). Cool white XM-L emitter was not perfectly centered on my sample, but is not bad.
The interface of the ED11 is revised from the older ED10. There are now three constant output modes and three blinking modes.
In keeping with the addition of a reverse clicky switch, turn the light on/off by clicking and releasing the tailcap switch. You can advance modes by clicking off-on quickly, or soft-pressing the switch from on (i.e., partial press and release, without a click)
With the head tight against the body, you can access the following constant output modes in sequence by clicking or soft-pressing the tailcap from on: Lo > Med > Hi, in repeating loop.
With the head loosened, you can access the following blinking modes in sequence: Fast Strobe > Slow Strobe > Beacon, in repeating loop.
There is no mode memory – the light always comes on in Lo (or Strobe, with head loosened) if you leave it off for more than a few seconds.
For information on the light, including the build and user interface, please see my video overview:
Video was recorded in 720p, but YouTube typically defaults to 360p. Once the video is running, you can click on the configuration settings icon and select the higher 480p to 720p options. You can also run full-screen.
There is no sign of PWM that I can see, at any output level – I presume the light is current-controlled, as claimed.
Strobe is a standard "tactical" high frequency strobe, measured at 9.5 Hz.
Slow strobe is a one-second On pulse, followed by one-second Off, in repeating sequence
Beacon mode is a quick flash once every ~2.1 seconds.
And now, the white-wall beamshots. All lights are on Max output on the identified battery type. Lights are about ~0.75 meter from a white wall (with the camera ~1.25 meters back from the wall). Automatic white balance on the camera, to minimize tint differences.
1xRCR (AW Protected 750mAh) Li-ion Comparison:
In general terms, the ED11 certainly puts out a good amount of light of max (at least initially). Note the overall spillbeam width is narrower than typical, due to the fairly deep reflector for this class. Overall throw is quite good, but with a broader and more diffuse hotspot that some lights in this class. Beam tint was about typical, with a slightly warmer centre/corona and a cooler spill.
All my output numbers are relative for my home-made light box setup, a la Quickbeam's flashlightreviews.com method. You can directly compare all my relative output values from different reviews - i.e. an output value of "10" in one graph is the same as "10" in another. All runtimes are done under a cooling fan, except for any extended run Lo/Min modes (i.e. >12 hours) which are done without cooling.
I have devised a method for converting my lightbox relative output values (ROV) to estimated Lumens. See my How to convert Selfbuilt's Lightbox values to Lumens thread for more info.
Throw/Output Summary Chart:
My summary tables are reported in a manner consistent with the ANSI FL-1 standard for flashlight testing. Please see http://www.flashlightreviews.ca/FL1.htm for a discussion, and a description of all the terms used in these tables. Effective July 2012, I have updated all my Peak Intensity/Beam Distance measures with a NIST-certified Extech EA31 lightmeter (orange highlights).
Initial max output is certainly very impressive on 1xCR123A – the highest ANSI FL-1 standard estimated lumens I've seen yet. But only initially – there is a timed step-down in output after 3 mins, at which point the light runs at a regulated ~360 estimated lumens.
On 1xRCR, initial max output is only ~10% brighter, and thus within a fairly typical range for modern 1xRCR lights. But again, the ED11 has a timed step-down at 3 mins, so sustained output will be lower (i.e., ~370 estimated lumens in my testing). See runtime graphs below for more information.
When matched for output, peak beam intensity throw is at the higher end of the XM-L class of 1xCR123A/RCR lights.
Thanks to the timed step-down at 3 mins, the ED11 has excellent overall regulation and efficiency on Hi. I am not sure what you could expect with repeated restarts, but I am sure you would have much lower runtime.
On Med level, the output, regulation and runtime patterns are remarkably similar to the Eagletac D25C and Olight S10. This is confirmation that the ED11 has current-controlled circuitry of equivalent efficiency.
Because the selection of output modes is organized by head twist (i.e., head loose vs head tight), no physical lock out is possible (i.e., screw threads can't be anodized). However, the recessed reverse clicky switch should reduce the risk of accidental activation.
The light lacks mode memory, and always comes on in Lo (or Strobe, depending on the state of the head twist).
Switch is a reverse clicky, so no momentary mode is possible.
Tailstanding was slightly unstable on my sample, likely due to the small surface area of the raised tailcap ridges.
The ED11 is a nice little 1xCR123A/RCR light, with an improved interface over the basic model twisty ED10.
The light remains reasonably compact, for a clicky-switch style light. Overall construction seems good, with the ED11 definitely sturdier than the original thin-walled ED10. Switch feel is about typical for a reverse clicky. The revised user interface is much improved my view, as blinky modes have been seperated from the constant output modes. Some people may have preferred a memory mode, but failing that, I personally like having the Lo mode start.
Output and circuit performance is very good. Like many lights, the ED11 has a very bright Hi mode initially, but then steps down to a lower Hi after 3 mins of continuous runtime. In fact, the ED11 is currently the brightest light on 1xCR123A in my collection at the moment (at least for 3 mins). This step-down pattern has the advantage of keeping heat down, and allows for improved overall regulation and runtime. In that regard, the ED11 has a very good current-controlled circuit - both regulation pattern and overall efficiency is excellent for the class. In fact, the output level and runtime on medium is virtually identical to the Olight S10 and Eagletac D25C.
Output mode spacing is generally good, although like the Olight S10, some may find the low-lumen Lo mode fairly dim compared to the Med/Hi levels. Beam pattern is very clean, with no artifacts on my sample. Spillbeam is slightly narrower than most lights in this class, but the beam pattern is very smooth (i.e., a nice broad hotspot, but still with fairly good throw for the class).
The ED11 is a nice update to the ED-line from Lumintop, and a contender to consider if you are looking for a compact clicky-style 1xCR123A/RCR.
