 A performance 

 ● Explosion-proof the highest level, inflammable and explosive places in the coal mine safety. 
 ● high-efficiency gas-discharge light source, high luminous efficiency, long life, the average life of up to 10,000 hours. 
 ● use of advanced optical technology designed to mirror, two-way glow, so that uniform illumination, light, long distance, especially for use in coal mine tunnel, 3 meters high when hanging lamps with light from up to 30 meters. 
 ● optimize the structure design and high-strength alloy casing, high strength, high impact resistance and impact performance. 
 ● special sealing technology and optimization of surface treatment technology, the lamps waterproof, dustproof, corrosion, to ensure that lighting in a variety of reliable operation in harsh environments. 
 ● Rings-style lamps can be installed, installation is simple and convenient. 

 2 Use 

 ● First, with the actual needs of the job site to determine where and how to install lighting, then according to distance from the lamp to the power contacts to prepare the appropriate length of Φ8 ~ Φ14 mm three-core cable. 
 ● Use a hex wrench to unscrew the terminal screws on the roof of the mouth, loosen the light conduit of the compression nut, respectively, the power cable through the gland nut, washer, filler introduced into the internal wiring terminals, the three core cable connected to fixed terminals, and then tighten the cable gland nut, the top cover back in place. 
 ● When changing the lamp required Allen wrench Unscrew the screw under the shell can be separated on the shell and lower shell, remove the bad bulb and replace the new bulb, replace the shell to the next. 

 Three note

 ● use, the light surface of a certain temperature, is a normal phenomenon; transparent pieces of center temperature is higher, not touch. 
 ● When installing lamps, lighting should be close to safe ground. 
 ● replace the bulb, wipe the glass, must turn off the power switch for 20 minutes and after cooling until the lamp.
