Sofirn LT1S
Emitter: 2700K warm white LED*18, 6500K cool white LED*18, Red LED*4
Operating voltage: 2.8V – 4.2V
Battery options: 1*21700 (make sure you buy the set with battery)
Dimension: 97mm (length) × 68mm (head diameter)
Weight: 257 grams(without battery)
Flashlight body: Aerospace 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.
Mode Memory: memorizes the last brightness level used in the general modes (Moon/Low/Med/High/Turbo)
Reverse polarity protection from improper battery installation
Low voltage warning: When the battery voltage is too low, the LED indicator in the switch will start to flash rapidly. Please recharge the battery.
Low voltage protection: The flashlight steps down automatically when the voltage is lower than 2.7V. It also turns off automatically if the voltage gets too low. Please recharge the battery.
Advanced Temperature Regulation (ATR) technology: As the temperature rises, LT1S is programmed to automatically step down and step up the brightness. These thresholds are set at 45°C, 55°C and 65°C. The higher the temperature gets, the more the brightness will drop. Once temperature decreases, brightness will be increased again according to your selected mode.
