Soonfire FD39 USB Rechargeable Bright Bike Light
[FD39]

Check out the video for this flashlight in action and see how bright it is! I can??t compare it to really expensive tactical flashlights, but I??d give it four stars. If I had one complaint, it would be that the beam could be tighter and more collimated. Nevertheless, the flashlight is very bright and can be submerged in water up to 1 meter. I tried it out in my kitchen sink (see the video) and it worked great.
