LED: Cree XM-L2 Neutral White (Nominal CCT 4400K) 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. Light Output (runtimes) High: H1 500 Lm (3min, then 304lm, total hr) or H2 304 Lm ( hr) / 187 Lm ( hrs) / 107 Lm ( hrs) Medium: M1 45 Lm ( hrs) or M2 19 Lm ( hrs) / 7.5 Lm ( hrs) Low: L1 3.0 Lm ( days) or L2 1.0 Lm ( days) / 0.28 Lm ( days) / 0.1 Lm ( months) Beacon Strobe Mode: 4Hz Strobe at H1 / 19Hz Strobe at H1 Light output are ANSI out the front (OTF) values. Runtimes tested (and parasitic drain estimated) using Panasonic Eneloop Pro AA batteries. Operating Voltage Range: 0.7V - 2.0V Battery: One AA size NiMH, lithium or alkaline battery. Panasonic Eneloop or Eneloop Pro is highly recommended. Batteries are not included in the box. Parasitic Drain: Negligible (much less than the self discharging of a battery) Beam Type 80 degree spill 10 degree hot spot Dimensions Head Diameter: 1.0 inch (25.4 mm) Length: 3.2 inch (81.3 mm) Weight 2.0 oz (58 gram) Features Battery capacity indicator (LED flashes 1-4 times, 4 short clicks to start) Automatic stepping down from High to Medium, and from Medium to Low when battery capacity is low Durable electronic soft-touch switch Smart user interface provides fast and easy access to all brightness levels and beacon-strobes. Precision machined unibody casing from premium grade aluminum bar stocks Proprietary heat sinking design bonds the LED board directly to the unibody aluminum casing Durable natural hard anodized finish (Type III Class I) Sealed and potted LED driver circuitry Battery reverse polarity protection Tempered optical grade glass Preinstalled bezel down pocket clip Smooth reflector Battery power can be disconnected by slightly unscrewing the tailcap to prevent unwanted activations or parasitic drain Waterproof to IPX7 (2 meters, 30 minutes)
