This is a new style of cordless and portable cap lamp, light weight and long lifetime Safety: All in one case with PC plastic material , make very good feature of explosion-proof. Protection in electrical short-circuit, automatic power-off on the socket , 100,000 hours LED’s Lifetime Reliability: The high strength case , optimized structure design and MCU control make the product more reliable Portability: Just a head lamp , Small in size , light in weight (only 215g for whole product), simple charging, easy usage Efficiency: more than 15hours at full brightness. more than 3000lux at starting time, and more than 2000lux after 11 hours continuous lighting. Battery usage lifetime about 1000 cycles. Display cap lamp number , time , battery capacity by 4 LED digital device (four squares is full , three squares means 3/4 capacity , two means 1/2 capacity, one means 1/4 capacity, one square blink per 20 sec. Means have to be charged again and the battery capacity only can light for about one hour) . Environmental: Li-ion battery is free for maintenance, and the material of li-ion is environmental, use 1Watt high power LED as the main light, and 6pcs 5mm backup LED’s to save power Economy: three times longer than lead and acid cap lamp and saving in maintenance makes the product more compatible in price When the energy is not enough for one hour illumination, the digital will flash, which can remind the mining worker to leave the workplace.
