A lot of lights to consider out there.. But 6 levels of light and 1 hour of runtime at 5000lm from such a small light is very efficient and amazing!
Most other platforms require much more size, wasted heat, and weight.... Even lithium will not meet these specs on another platform besides led.
Instant on/off is a plus against intruders delivering advantage of instantly blinding them....
I can see this being very practical should I need a light in one hand and pistol in the other. I still remain agile regardless if I'm hog hunting or defending myself.
Every light with multiple leds seems to cast less throw due to need for deep/large reflectors for each led to do the trick... Making a decent thrower too big.
Some good attempts though at the expense of more weight, size, and less runtime related to basically having 3 or even 6 leds in one host (3 - 6 smaller flashlights in one).
I have an SST 90 with 2200 lumens
http://www.amazon.com/dp/B003CT5GOG/?tag=cpf0b6-20 and it's a great light "bar none" but it uses 6 - 18650s, I can't imagine twice the muscle with another single focal point and less batteries.....
I'm not an advocate of lighting 3 matches versus one torch if I want throw.
Definitely nice technology for less money!
