TS21 delivers a maximum output of up to 3500 lumens with a maximum range of 217 meters. Its side switch controls all functions: power on/off, battery indicator, output level and change of mode groups. The sophisticated Andúril UI provides a both user friendly and highly flexible interaction as well as simple one-hand operation.
Emitter: 3x SST20
Operating voltage: 2.8V – 4.2V
Battery options: 1x 21700
Dimension: 113.4mm (length) x28mm (head diameter)
Weight: 78 grams (without battery)
Flashlight body: Aerospace grade 6061 grade aluminum alloy, CNC manufactured to hard-anodized to military grade specification type III, anti-abrasive finish to get solid built body, anti-crash geometry and better heat exchange.
Water resistance i.a.w. IPX-8
Mode Memory: memorizes the last brightness level used in the general modes (except Strobe)
Low Voltage Protection: If the battery’s voltage is lower than 2.8V, TS21 steps down automatically to avoid battery damage by over discharge. At 2.7V the flashlight will turn off automatically.
Advanced Temperature Regulation (ATR) technology: By default ATR will reduce the brightness level automatically when the driver temperature reaches 45°C to prevent overheating. You can set a different temperature threshold by following the thermal configuration guideline.
Firmware: TS21 uses open source software called Andúril, distributed under the terms of the GPL v3. The source code is available from http://tiny.cc/TKAnduril
