Performance characteristics of on-site investigation lamp: high-quality light source: selected high-power imported LED light source, excellent visual effect, extremely high light efficiency, and service life up to 65,438+10,000 hours; Sturdy and durable: the shell is 6061-T6; Ultra-wide lighting: the spot diameter at 2 meters can reach 790mm, and the spot uniformity can reach 92%; Constant brightness: the lamps are driven by constant current, and the brightness remains constant during working hours, which changes the situation that the old lamps are bright when fully charged, and the brightness is obviously dimmed in the later period, which cannot meet the use requirements. Hollow aluminum material can withstand strong impact and impact, and the surface is anodized with high quality, which can effectively improve wear resistance and corrosion resistance; The structure is optimized, the overall sealing is good, and the feeding port is closed, so it can be used in heavy rain; Intelligent protection: the internal circuit is designed with devices to prevent short circuit, overcharge and overdischarge, which can effectively protect the battery and prolong the service life of the flashlight; Intelligent charger is equipped with short circuit protection and charging display device; Portable and flexible: small size, light weight and simple operation, especially suitable for carrying and field maneuvering. In order to meet the individual needs of users, such as the standard configuration of SM-7034X four-band uniform spot detection lamp can not meet the work needs of users, our company can customize it according to the requirements of customers. ?
