In the world of “tactical” flashlights, it’s hard to beat the simple, robust and reliable design of Surefire lights. However, the quality you get from a Surefire comes with a steep price tag that many of us find hard to justify. In this review, we will take a look at the value-priced Techlite Lumen Master LED that I recently purchased at Costco. I will compare it side-by-side with one of my favorite Surefire lights, the E2D Executive Defender.
CRITICAL UPDATES POSTED: This post refers to the first generation Lumen Master with the translucent tail switch. Techlite has made major updates in their 2nd Gen lights. You can read all about the new lights here.
At first glance, the Techlite has many similarities in appearance compared to the E2D. However, they are two very different devices. First of all the Surefire above is not using an LED, but instead relies on an incandescent bulb to generate it’s 60 lumen output. Surefire also offers an LED version of the E2D for about $40 extra. The Techlite uses a CREE LED to produce the claimed 160 lumen beam. The difference in perceived luminosity however, is not as extreme as you would think. The Surefire produces a very bright and focused spot beam with very little flood lighting effects. Though it is not an adjustable beam, the incandescent light is crisp, white and defined, making it an excellent blinding device in the dark. The Techlite on the other hand, produces more of a blue colored light that is partitioned with a spot beam and a flood beam. It is also adjustable so you can fine-tune your spot light diameter. Having more flood lighting makes Techlite very useful for utility purposes such as camping or performing repairs. Both lights are plenty bright to cause temporary blindness in an assailant’s vision on a dark night.
The next major difference is their size. The Techlite is significantly larger in all dimensions. However, it is not nearly as robust as the Surefire. The Surefire body, lens, and bezel are thicker than the Techlite. This gives the Surefire more of a feeling of durability without any added bulk. This is something to consider if you plan on carrying the light on a daily basis.
If we look at the activation switches of the two light’s, we see even more differences. The Surefire uses a simple but reliable switch with momentary on/off, and constant on/off capabilities. The Techlite has several additional options built into the switch. One click gives you a low intensity beam that draws less power for extended battery life. Two clicks give you a high intensity beam for full power lighting. And, three clicks give you a strobe effect that can be used to disorient an attacker, or function as a distress beacon in an emergency. It also has momentary on/off like the Surefire. However, I’d like to note that the momentary on/off function on the Techlite is not instantaneous. There is about a 1-second delay, which can be a problem when seconds count. I believe that this multifunction switch can be counterproductive in a “tactical” situation where simplicity seems to work best.
The next major difference is what powers these lights. The Surefire runs on a pair of lithium 123A batteries, and the Techlite uses three AAA’s. The 123A batteries are more expensive, they drain faster with the incandescent bulb (75 min burn time), and the E2D light lacks “constant drain” technology. This means that the light will become less bright as the batteries are used up.
The Techlite Lumen Master LED has “constant drain” technology, meaning that the light output is regulated until the batteries reach a critical low point of drainage at which it just stops working. The Lumen Master battery life is not bad, but not great. You may get an hour or more of continuous use at best. Nonetheless, AAA batteries are cheap, and readily available virtually everywhere. Also, it should be noted that the activation switch does drain the batteries even when the light is off. So, if you leave it sitting for a long time with batteries inside, it will be dead when you get to it. The Surfire does not suffer from this issue.
Another feature the Techlite offers is the low battery indicator. When the batteries reach 20% capacity, a small red LED turns on in the translucent activation switch to let you know it’s time for a swap. Unfortunately, there is one critical problem with the Techlite low battery indicator. When the battery power reaches the critical 20% level and the low battery indicator turns on, the “constant drain” regulator makes it so that the flashlight will not turn on anymore. This happens without warning, leaving you (in an unpredictable instant) without a working light. I believe that the low battery indicator should turn on before the battery fails. This is a major weakness in any “tactical” situation. What is the point of having a low battery indicator if it does not warn you ahead of time?
The final diagnosis…
As I mentioned before, it is hard to beat a Surefire when it comes to durability, reliability, and simplicity… three things that I believe are essential in a “tactical” situation. However, it can be hard to justify spending $100-$150 on a flashlight unless it also doubles as a light saber. The Techlite Lumen Master costs about 1/20 the price of the E2D LED version, but you get what you pay for. My first Lumen Master failed after less than two months of very light use around the house, and the switch tends to be finicky and unreliable; hardly desirable in a defensive “tactical” light. The E2D on the other hand, has been working flawlessly for several years now despite being thoroughly abused.
Both lights are water resistant. Both come with a body attachment; the E2D has an integrated clip, and the Techlight comes with a lanyard. Both are made of high grade aluminum, and both have strike bezel’s on their cap and tail ends.
As much as I like the Techlite and the value it offers, I am not a big fan of the activation switch, or much less the lack of reliability. And, the bulk of the Lumen Master is a bit taxing on my limited pocket space. The Techlite is more complex, less robust, experiences instantaneous battery failures, and suffers a delay in the momentary on/off switch. Regardless of this, I do plan on buying another two pack from Costco because they are a decent value for a utility light. I will put one in my vehicles, my motorcycle, and my tool box… and plan on keeping the battery insert out during storage.
Unfortunately, I cannot recommend the Techlite as a viable alternative to a high-end “tactical” light such as the E2D. It just does not contain the right balance of functional elements that I prefer in a life or death situation. Despite the fact that the Techlite is not a perfect “tactical” lighting solution, it is still pretty useful for such a low price.
WAS JUST GETTING READY 2 BUY A 359.00 $ 1700 lum. flash light good thing i read up on these 1
Bought a package of three TechLite’s at Costco. One works normal but the other two go dead after about 3 to 5 days even if the light is never turned on. Tried several batteries with the same result. I do not know if it is the low battery circuit or what but the lights are junk.
I purchased a 3 pack of these flashlights last summer from Costco and have had absolutely no problems with them. They no longer have the battery light in the push button and the lens is no longer adjustable. Use all three a lot and the original batteries are still in them working fine.
Wow’ I don’t know what you guys are Talking about I had these flaslite’s going on 5 years. Now ,and had no problem I’m going back to get me som more
I have two of the units. The switch does not work on either. All I can get is a flashing red light. I will try a switch replacement as suggested above.
the battery holder sucks! it didn’t work
For all these outdated reveiws….I have the three pack witch I purchased at Costco Ive had them for months, I use one dialy the other two are on standby with batteries intact they all work as should. Note: these do not have the low power indicator switch… they have a plain black three position unit with momentary feature I would say this was the solution to the battery drain problem…Battery life is good and produces a nice bright beam..As the issue of battery holder The holder in my lites has givin me no problems and seems robust enough to me..All in All these are great lites for the money I belive this lite has been revised due to switch and is very reliable…Great little lite.
I purchased a three pack from Costco about two months ago. I have absolutly no problems with them. They do not have the low battery indacator just a black rubber button. They have the same batteries in them that I put in them. Kirkland alkalines.I use them a lot and the battery pack still reads 4.35 volts. Fresh batteries read 4.6 volts plus. The wife uses hers every night. The other one is in our bed room. All working fine. I’m glad I did not buy the early ones. I also just found out about how to use the button to turn them off without going through th three steps. Thank you who ever posted that info.
Here is a link with a guy that found a fix for the battery drain issue. To be honest I have not notticed it on mine that have the black switch (not the white/clear) but apparently the ones with black also have the issue But all of mine have been fine for over a year.
Here is the link for the “fix” but like above I would recommend taking the white switch ones back and buying black ones if you got it from Costco.

Just an FYI guys…. Costco Return Policy lets you take them back even without a recite you just need to take all of them back you cant just take one. There is no limitation on how many days you can take them back even 5 years after the date of purchace no problem (I used to work for Costco) If yours stopped working take it back and buy the new 3 pack set which I like much better for the same price. They are slightly different but very similar.
is there any way we can ”neutralize” that dam ”battery eater switch” ? …
Every time i need that flashlight for emergency situation, the batteries are drained !
Realizing the issue of battery drain while not in use, I simply cut a small nickel-sized circle of plastic (from a packaging blister-pack) and inserted it between the battery and the screw on cap. This effectively disables the battery drain. Just need to remember to remove it when the flashlight is needed. I dislike the drain issue and didn’t realize this was a problem till reading online. But these flashlights are placed around the house for occasional use when the lights go out, so not a big deal to “reactivate” them when needed. I can live with that.
Took me about a second to think of battery drain issue…
Unscrew the Rearcap and flip over the battery retainer so that both springs are facing each other. Rethread cap turning just once or twice.
I have had my pair of techlites for a few years and luckily have had 0 issues.
As you say “a real pity because they are sorugged and bright”……..the suggestion about keping it in the car glove comparment for an emergency was good but not if it runs down on its own. I therefore thought it might be a good idea to prevent it running down.
Take a small piece of thin plastic sheet (cut from a plastic milk bottle)……..draw a circle
on it around a small coin with a Sharpie……..cut out the disc with a pair of scissors..
Unscrew the base of the torch and put the disc on the bottom of the battery. Assemble torch and store in glove compartment. In an emergency, remove the disc and screw back the base.
Yes, the battery holders break easily…candidly, they are junk. I have already had two of them break inside the flashlight. Other than that, the flashlight is a good value.
I like the Coleman LED 90 Lumens Flashlight – $17.00 at WalMart can’t beat it.
If anyone could tell me where can i get a replacement tri battery holder which fits into the flashlite. It was broken when the wife nolan ryaned it at me during a small disagreement. Please advise as i dont want to throw this lite away.
Thanks, Mike
Pure Junk! If you don”t use it regularly the batteries drain, acid is released from the batteries and the plastic holder for the batteries is toast. DON’T WASTE YOUR MONEY!
ditto on the comment from Russell Smith (7-23-11). My cassette has also fractured and I can’t seem to locate a replacement part.
I have tried to find where I can get a warranty replacement for the 3-Cell cassette. Both of the two I own are fractured and will not hold the batteries correctly in place.
Anyone have a phone number or web site for the TechLite manufacturer?
i purchased the 3-pack techlite from Costco last year, for time i only store with rechargeables batteries and check them every couple months. one of them i store with standard batteries and for 3+ months still has same brightness and redlight has not come on. i like them and refer them to others.
I purchased 2 “lightmates” from Costco and found them to be an excellent product. So when I saw a 3 pack of “techlites” on display at Costco those were also purchased this past winter. What a piece of junk! The red low battery warning lite comes on despite the batteries being fully charged. In order to get the lite working again the batteries must be removed & then reinserted… and this only works for little while and the process begins again !!!! What will you do about it?
I have two of the techlite lumen master. I bought them some time ago at Costco. Now they are both flashing red, changed batteries, but it did no good. They turn on once and then stop and start the flashing again. I don’t use them very often. So should I just toss them. Needless to say, I am very disappointed.
Excellent review and unfortuantely, the drain feature or so called low-battery indicator is the culprit for a discouraging review. I kept changing the batteries every two months and finally figured out it’s not the battery but the flashlight.
I will only place batteries in the unit when I need it…like camping, late night picnics, etc.
Thank you for confirming what a lot of us didn’t know. I want to write to the manufacturer and Costco, but it probably isn’t worth the time.
Cheers’ Dwight
I also have experienced the battery unit failure after a few months of very low impact use, seems to be the 3rd battery change. i read one poster say take the flashlite apart, push the button a few times and it will reset the low-battery indicator mechism but that did not work for me. Priceless.
