I use my X21 to keep track of my 3 dogs as they wander around the forest surrounding our home during the winter months. (We live in Washington State, so winter lasts for a while here.) The big advantage of the X21 for this use is that it can cover a very large area with excellent illumination over the entire area. At 1000 lumens, it beats anything out there. I can easily illuminate an area covered by a distance of 100 feet and a circumference of 40 feet with the X21. The illumination from the X21 is truly "daylight at midnight".
The really big deal of the X21 (and, indeed, all LED Lenser flashlights) is that the illumination is so very evenly distributed across the entire range of focus - no dark rings or variation in illumination within the illuminated area. Also, battery life is excellent - I only change batteries once a year, and I really use this flashlight a lot during winter months. The shoulder strap provided with the X21 is also excellent - it allows me to easily carry the X21 as I follow by dogs through the forest.
My only gripe with my X21 is that the focus ring does not slide smoothly - it requires some "wiggling" to get it to move. However, this may just be a problem with my particular unit, and LED Lenser may have addressed this problem in the 3 years since I bought my X21. I only wish that the slide focus on my X21 worked as well as the slide focus on my LED Lenser P14. If I could give a 4.5 star rating, I would do so based on this problem with my particular unit, but given the other advantages of the X21 over any other flashlight, I decided to move to a 5 star rating versus a 4 star rating.
Bottom line - if you need to illuminate a large area with a portable flashlight, you simply can't go wrong with the LED Lenser X21.

I bought this for $300 somewhere else online and I couldn't believe I was dropping $300 on a flashlight, but I haven't regretted it for a second! It's AMAZING! When I use it outside at night it's like the sun came up because it can light a quarter acre in sunshine! It's so powerful that the beam is actually visible in the air when you point it up - it's light a searchlight.

I don't know how long the batteries will last since I'm still on my first set. I use it on the High Power most of the time, but the low power is okay for general lighting in small areas, but the high power will amaze your friends (and passing aircraft) for sure. The is the most expensive, but certainly the best flashlight I've ever owned.

Warning: After using this flashlight, all others will pale in comparison, both literally and figuratively.

There are cars and supercars. There are models and supermodels. There are flashlights and superflashlights. This is definately a superflashlight. The LED lenser X7 and the X21 are the same light. The X21 is the European name for it, that's all. At first I thought they were different, but I did my research... (so you don't have to. ;)

I have been a flashlight nut for over 40 years, and I have seen a lot of them in my time, but this is GONZO! Put your hand in front of it and you can feel heat, from as much as 3 feet away! (No big deal for a bright incandescent, but can you say LED?) On the tightest beam focus, on the brightest setting, I find it difficult to look at the spot on a wall or anything reflective (like white paint) if it is withing 15 or 20 feet. I am NOT a person that complains when you turn on the light after I have been sitting in a dark room for an extended period of time. If you are, do NOT look at the reflected light (from somthing white, or even marginally reflective) from this unless it is 30 or more feet away. I am not kidding.

I have a LED Lenser P-17 and I love it ($90 / 228 lumens and well worth every penny), that I use every day. It can project a spot on a cloud - something I have always wanted a flashlight to do! This has 7 of the same LEDs in it, making it fantastically bright, and I really wanted to have one for a long time. But when it was intoroduced, $700 was just plain too much. Now they are roughly $300. Still a LOT of money... So when I recently got the chance to get this at a massive discount, I went for it. No regrets!

Unofficial dstance test: There is a stair tower at the parking garage, where I work.

November 12, 2008. Just got my Led Lenser X7 yesterday. Took it out for a field test with Led Lenser H7 and Led Lenser P14 to compare with. X7 on Low Beam approximately = H7 with dimmer switch on about 65% (a little past half way). My guess it that it's anywhere from 80 to 100 lumens at this setting (1st click). High Beam (2nd click) is definitely bright. It's not overpowering (unless you shine it in somebody's eyes)- not overwhelming, but a really good light. Couldn't honestly tell much difference between High Beam and Max Beam (achieved by pressing & holding switch). On flood setting saw a dark ring around outside of beam. There is spill outside of that. The the beam inside of that ring is quite even- beautiful light. Not as white of a beam as the H7- more yellowish, but not by a lot. It is technically one hand focusable, but I found it's more practical to use a second hand to focus the beam. (The P14 in comparison is much easier to focus using only one hand) The sliding mechanism for the focus beam uses some sort of grease to allow smooth gliding. You see it when you use the end piece slider to focus the beam to a spot. The P14 in comparison has an entire head that slides back and forth. I doubt that either one is waterproof. I wonder how the X7 would do over time in a desert environment such as Iraq or the Sudan. Also, I should point out that there are no guarantees made by Led Lenser as to this flashlight being weatherproof, shockproof, or even water resistant. This is an amazing flashlight, but again, I'm not sure how impact or weather resistant it is. As far as beam throw, I was easily seeing things 800 ft. away. I say easily, because you can see things much farther, but I'm talking about EASILY.Read more ›
