* EXTREMELY BRIGHT--> up to 630 lumens on turbo mode. However, it also has 13 lumens, 93 lumens, and 277 lumens. This allows you to compromise between brightness and battery life, and to use it for different tasks.
* Runs on inexpensive AA batteries (8 of them), rather than on lithium or 123A's. It can use rechargeable batteries.
* Each intensity (low, medium, high, turbo) has slow flash, fast flash, SOS, and tactical strobe abilities.
* Hard aluminum body, resistant to almost any mishaps you might get this light in.
* Can run on 4 AA batteries if that's all you have.
* The low output is very useful, and it can run for 130 hours.
* Digital regulated output will maintain the brightness stable even when the batteries are low ( will not dim as the batteries become wasted).
* Has an anti-roll design.
*It is waterproof (it was tested by being submerged in 2 meters of water, in which it lasted waterproof for 30 minutes). This means you can use it in the rain without fear of it being damaged).
* Excellent peripheral light and great "throw."
*Includes a nice carrying case, a shoulder strap, wrist lanyard, extra O-rings, and and extra rubber switch boot.
* You can only use the turbo mode for no more than 15 minutes at a time (according to manufacturer recommendations).
*If you use lithium batteries, you void the warranty.
* Batteries are NOT included.Read more ›
Other notables, it runs off 8AA batteries, but will operate off 4AA batteries with no decrease in light. It has 4 settings, with 4 corresponding strobe functions. The batteries will die on you after about 2 hrs constantly on high, but they'll last for weeks with normal use on the 1st, 2nd, or 3rd light settings. It advertises that it's completely submersible to 8 feet, but I'll never do that. It is good to know that it will most likely be perfectly fine in a rain storm though. As far as size, it is a tad big and heavy for a tactical, but I absolutely don't mind. It feels solid and unbreakable and I like that.
I love this flashlight. Do I need a flashlight of this magnitude, no. Fun to play with though, absolutely. Worth the money I spent on it. . . I don't know. I suppose it depends on how much you have and are willing to spend. If you simply want the brightest AA flashlight on the market however, this is it.
What attracted me to this light was the fact that it could run on 4 AA's or 8. I didn't want to bother with special lithium batteries or the 123 cells. This light is extremely bright for a AA light, and no words can describe it, you have to see it in person. It has low, medium, high, and turbo. I find that medium is a good all-around setting and leave it on that until I need to really light things up with turbo.
Overall it's an amazing light, something you need to try to believe, you won't be disappointed.
Brightness: The low setting of 13 lumens is slightly brighter than flashlights with Nichia LEDs and having better throw. The runtime is estimated at 150 hours on low. The medium setting of 97 lumens is very powerful, enough for just about any use, including lighting up a room, and has a runtime of about 20 hours. The high of 277 lumens with a runtime of about 6 hours appears slightly brighter than the Fenix LD20 on turbo. The turbo mode with 630 lumens is considerably brighter than the LD20 and the output readings are equivalent to a 10 watt HID spotlight. Took it outside and it performed like a spotlight. Indoors, I could shine the flashlight up at the ceiling and it lit the living room like a ceiling light. It appears that this is truly the brightest flashlight running on AA batteries, which is great as I only consider products that use AA and AAA batteries. The only brighter flashlights are usually the high-power HID lights that use special batteries and have short runtimes.Read more ›
