Bought one in May from Amazon and have used it daily since without a need to replace the batteries yet. Also bought a 12 pack of batteries!
A few features of the light are:
- Utilizes a Premium (R4) Cree 7090 XP-E LED with a life of 50,000 hours
- Two modes of output, selected by turning the bezel
- General Mode: 11 lumens (65hrs) -> 75 lumens (8hrs) -> 140 lumens (4hrs) -> SOS
- Turbo Mode: 257 lumens (1.5hrs) -> Strobe
- 33 days of survival use (2 continuous hours per day on the lowest setting)
- Digitally Regulated for Constant Brightness
