Acebeam UC15 Keychain LED Light - Options

On the "high" setting the UC15 delivers a healthy 250 lumens using two AAA batteries, or an awe-inspiring 1000 lumens when using two rechargeable 10440 lithium-ion cells. Coupled with a 107-meter throw from the latest Cree XP-L2, this is more than enough to read a street sign or light up a front yard. Better yet, the UC15 provides a "mid" setting of 82 lumens (200 lumens with lithium-ion cells) and a "low" of 10 lumens, which is enough to read a map or find your way to the bathroom, and it can maintain this output throughout the longest night! Simple and intuitive operation, a low-battery-warning indicator, IP54 sealing and rubber switch and keyring connectors combine to make this the gift that keeps giving - for yourself or anyone else!
