(Produk ini tidak termasuk battery dan charger) Main Features and Specifications LED: Cree XHP35 Cool White (Nominal CCT 5700K) 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 1300 Lm (PID, approx 2.2 hr) or H2 670 Lm (PID, approx 2.8 hrs) / 360 Lm (4.3 hrs) /160 Lm (12 hrs) Medium: M1 70 Lm (33 hrs) or M2 32 Lm (73 hrs) / 12 Lm (8 days) Low: L1 3.8 Lm (18 days) or L2 0.43 Lm (2.8 months) / 0.06 Lm (5.1 months) / 0.01 Lm (7.1 months) Beacon Strobe Mode: 0.2Hz Beacon at Low / 0.2Hz Beacon at H1 / 4Hz Strobe at H1 / 19Hz Strobe at H1 Light output are ANSI out the front (OTF) values. Runtimes tested (and parasitic drain estimated) using ZL634 batteries. Runtimes of the two PID controlled levels (1300Lm and 670Lm) vary greatly with ambient temperature and air circulation.
