GTZM2300-B High Brightness Micro-Torch( Anti-Explosion Type) Applicability: for floodlight in the (electric power, railway, metallurgy, mining, ports, municipal services and other industries) factories, stations, stadiums and railway tunnels, bridges and culverts, etc. 1.Features: 1.The light source adopts Ultra-high-power and the high bright white LED of 1w.3w with high light efficiency and 1,000 meters visual distance. It owns the functions of lighting and distance signal warning; 2. The product adopt smart chip to control the constant current output, to ensure the stability of LED brightness and to guarantee the lighting effects. Output circuit employs smart anti-polarity protection, to avoid LED damage in the condition of battery polarity being wrongly installed while customers are replacing the battery. 3. The product use high-energy batteries without memory. The super-large capacity battery with low self-discharge rate can stand long. The smart battery is economic as well as environmental protecting, with protection devices preventing over-filling, and over-discharging. When the discharge capacity reaches the protection voltage, the intelligent protection board will automatically cut output current off. So the external voltage of the measuring battery is 0V and the batteries are fully protected. The intelligent protection devices are activated once the charger gets plugged and recharging begins. There are also intelligent devices that will prevent over-charging. The power supply will be automatically cut off when the recharging finishes, effectively protecting using life of the battery, which can be charged and discharged at any time. 4. The product shell is finished through precision machining with light aluminum alloy. The nice easy-to-operate product can be worn on the wrist or placed in the pocket, with its refining structure and good waterproof performance. It can maintain the good performance under high or low temperature and high-humidity environment, and can also be used in all kinds of bad environment and climates. 5. 1.5 meters high from the lighted. GTZM2100 illumination can achieve 800lux or more with GTZM2300 illumination 1200lux or more. While working the maximum temperature of GTZM2100
