Where is the proof light quality is better?

Zhe Jiang Yurui Lighting Co., Ltd. specializes in producing led proof lights, explosion-proof floodlights, explosion-proof lamps for light, metal halide explosion proof lights, explosion proof lights, glare through street, through the emergency lights, three anti-corrosion lights, moisture proof light, explosion-proof flashlight, explosion-proof work lights, portable explosion-proof searchlight, led explosion proof industrial roadway lights and other lighting products. First, the explosion-proof lights before applicable to flammable and explosive safety, for a variety of indoor and outside the workplace. China's coal industry, the use of oil, Sinopec, CNOOC, electric power, metallurgy, railway, steel, shipbuilding, military, aerospace, public security and fire, chemical, government departments and large enterprise fixed lighting needs. ? Second, the performance characteristics 1 explosion-proof lights, explosion-proof function: proof has been certified by the national authority, in full accordance with the national explosion-proof standards, safe and reliable operation in explosive hazardous areas. 2, the light efficiency energy-saving: the use of high-intensity gas-discharge light source, light and soft, the color is good, with an average life of more than 10,000 hours. 3, the professional design: good design and surface sealing, durable, dust corrosion. 4. Installation: pendant, ceiling and wall-mounted, easy operation. Third, the main technical parameters of explosion-proof floodlight mark Exd || IICT4 rated voltage 220VAC 50HZ Housing protection IP65 Insulation Class I Anti-corrosion grade WF2 Inlet thread G3 / 4 from the introduction of cable Ф8-Ф14mm than 4 Dimensions Ф270 × 460mm ( OD × H) Ф325 × 120mm (ballast box) Weight 6.56Kg (lighting) 6.25Kg (ballast box) Fourth, explosion-proof lights equipped with light source rated power flux order number average life CGT8130-J400 MH gas the discharge lamp 400 36000 20000 CGT8130-N400 HPS gas discharge lamp 400 50000 28500 CGT8130-J250 MH gas discharge lamp 250 21000 20000 CGT8130-N250 HPS gas discharge lamp 2502750028500? Five, explosion-proof lights use 1, according to the actual job site lighting necessary to determine where and how to install fixtures and ballasts, and then press the lamp to the ballast and ballast distance contacts to three core cable from the 220V power contacts ready corresponding length (distance of not more than 2 meters available equipped with lamp cables). 2, when the lamp ballast contacts over two meters distance, the need to replace the three-core cable. Namely with a hex wrench to unscrew the lamp housing six hex bolts, remove the rear portion of the lamp, remove the lamp comes with three core cable and wiring according to the original three-core cable connected to the prepared well. 3, with a socket wrench bolts fastening the ballast on the cover, remove the cover, the three-core cable luminaire end the introduction of ballast cavity through the introduction of ballast output device, the red line black line (or blue line), yellow and green lines are connected to the terminals 4,5,6 ballast, and then tighten the compression nut. 4, will be ready three core power cable cord through ballast input device, the introduction of ballast cavity, then the L line (FireWire), N (neutral), respectively, received ballasted ground 1,2,3 bit on the terminals, and tighten the compression nut. 5. Close the lid and tighten the ballast holding bolts, and finally the other end of the three-core cable connected to 220V power supply according to explosion-proof requirements. 6, replace the bulb, cut off the power and check the hanging chain is hung, then turn on the lights with a hex wrench in six hex bolts on the housing and carefully pull down part of the lamp body, the lamp body and lamp shell separation, unscrew the old light bulb replaced with a new six-lamp, explosion-proof lights Note 1, the installation and maintenance of lamps, must be cut off. 2, when used, has some light surface temperature is a normal phenomenon, Transparency center temperature is higher, not touch. 3, must be used with the company's ballast. 4, wall-mounting, installation angle can not be greater than 45 °. 5, lamp starting current is 2.5 times the normal operating current, 250W lamp starting current of 2.8A. 6, the lamp housing is equipped with shock-absorbing foam, be sure to remove when you first install and use. ?? Warning: 1, prohibited charged open lamps. 2, be sure the installation of lighting the lamp housing ground and make it secure. ?? Seven, explosion-proof light quality assurance of the product in strict accordance with ISO9001:? 2008 international quality management system standards for quality control to ensure product quality is higher than the national standard, fully meet the design requirements, the product of 7-year warranty (one year lamp warranty ), from seven years from the date of purchase, the product under normal use of any failure by the company responsible for maintenance free.
