You guys are talking about big spotlights, no flashlights. Flashlights that you can get over the counter with 1,000.000 candlepowers do not exist.
The most powerful incandlepowers over the counter are the Ultra Stinger and the Surefire M-6, the Ultra Stinger is rated at 70.000 candlepowers, the Surefire M-6 uses the better figure of total light output, LUMENS, any serious flashlight will quote you lumens, the camdlepowers is the amount of light at the hot spot only, not the amount of light that the device puts out.
Now, a Surefire M-6 at 500 lumens is the most powerful of the flashlights (except for the MAG 951 -a modified Maglite 3 D- that will output 951 lumens, Such a light will overpower many 1,000.000 candlepowers spotlights)
I happen to have both lights, and I want to show you some beamshots.
Surefire M-6 (500 lumens)
MAG 951 (951 lumens rechargeable, FREE TO RUN)
These beamshots coming from 43 yards away, camera at 15 yards
Surefire M-6 (500 lumens $400.00 $30.00 in batteries per hour)
MAG 951 (951 lumens rechargeable flashlight $200.00)
Yes, these are the two more powerful flashlights in the world, the Surefire M-6 in used by SWAT teams in entry operation, such lights blind the oponents.
The MAG 951 is making entrance in the same field, also is used by Ranchers to shot coyotes that get too close to the hen house, I know several that have a MAG 951 mounted on a rifle by the kitchen door, such light permit making shots at 200 yards on coyotes by only one person. (no need to have a pardner with spotlight handy).
The MAG 951 been rechargeable and with a longer run time than the spotlight will be a better tool for navigating while duck hunting.
