Has an excellent explosion-proof, anti-static effect, can work in flammable and explosive places (including containing hydrogen, acetylene, methane and other gases mixed environment). High-efficiency light-emitting semiconductor technology, the same brightness, the 70 percent energy saving, pollution-free lithium batteries, thus energy saving and environmental protection. No memory battery capacity can be high, environmental protection, the stability of charge-discharge performance, low self-discharge rate. Before the bullet-proof shell for high strength plastic, after the shell is not broken super. Engineering plastics are to make our products have a high impact resistance. Optical part of the use of long-life light-emitting diode 1W without replacement; waterproof performance, sophisticated structure, it can ensure that the lights can be subjected to a strong collision and the impact of the degree of enclosure protection IP66. Uses two sets of light source, at the main lights and backup lights, lights from a key replacement. P leasing in appearance, small size, lightweight, product integration, without restraint, to reduce the load on the workers to improve work efficiency.
