Zebralight SC52 AA Flashlight Cool White
What's New: Record breaking 280Lm ANSI from one AA Eneloop (more output with Energizer L91 lithium),    Record breaking 3 months runtime at min output (longer runtime with Energizer L91 lithium),    All levels are current regulated,    Battery capacity indicator (LED flashes 1-4 times. 4 short clicks to start),    Low battery alert when the light is switched Off with AA batteries (LED flashes every 80 seconds if the battery voltage is below 1.06V),    Programmable M2 and L2,    LED driver circuits sealed completely from the battery chamber,    Recessed switch (improved from SC51).Main Features and Specifications -     LED: Cree XM-L Cool White (Norminal CCT 6300K).    User Selectable Levels: 3 main levels (High, Medium and Low). Each main level can be programmed to one of its two sub-levels. The second sub-level of the each main levels can be further programmed to different brightness levels or strobes.    Light Output -         High:         H1 280 Lm (0.9 hrs)   or    H2  172 Lm (1.7 hrs) / 108 Lm (3 hrs) / 4Hz Strobe,        Medium:    M1 50 Lm (7.5 hrs)    or    M2   25 Lm (12 hrs) / 12 Lm (27 hrs),        Low:         L1   2.7 Lm (4 days)   or    L2   0.34 Lm (3 weeks) / 0.06 Lm (2 months) / 0.01 Lm (3 months).        Light output are ANSI out the front values. Runtime tests are done using Sanyo 2000mAh Eneloop AA batteries. Light output with 14500 batteries are the same except that the H1 is 500Lm for the first minute and then steps down to 280Lm.    Operating Voltage Range: 0.7V - 4.2V    Battery: One 1.5V AA (NiMH, lithium or alkaline) or 3.7V 14500 Li-ion battery. Batteries are not included in the package.    Parasitic Drain: Negligible (equivalent to 16 years, much less than the self discharging of a battery).    Beam Type:        80 degree spill,        12 degree hot spot.    Dimensions -      Diameter: 0.93 inch (23.6 mm),       Length:    3.08 inch (78.2 mm).  Weight: 1.4 oz (40 gram).Accessories in the package:  Two o-rings
