Ultracapacitator Flashlight Charges in 90 Seconds, Doesn't Use Batteries

November 10th, 2008 by  


I’m always on the lookout for dependable flashlights, so the upcoming release of 5.11 Tactical’s Light for Life has really piqued my interest. Instead of batteries, the flashlight uses an ultracapacitator to hold its charge.

According to the company, the flashlight can perform 50,000 charge/discharge cycles with no degradation of quality— that’s one charge a day for over 135 years. And if that isn’t impressive enough, it can go from being dead to fully charged in 90 seconds. The flashlight provides 90 minutes of light per charge.

The 16 oz. Light for Life has no replaceable parts, and requires zero maintenance. At $169.99, it’s somewhat of a bargain considering it may be the last flashlight you ever buy.

For detailed information on the inner workings of the Light for Life’s ultracapitator, check out the flashlight’s blog.
