Material: die casting aluminum the light body, toughened glass surface cover, surface polyester powder coating Light color: white/warm white Projection distance: acuities as well Single LED power: 1 * 20W Optional lens: 120 ° Protective level: IP65 Environmental temperature: 45 ° C 20 ° C Control mode: constant-current driver Colour effect: monochromatic project-light Life expectancy: 50,000 hours The input voltage: AC85 265V Flux: the 20000LM 2 years quality: Green environmental LED seven advantages: So high efficiency and energy saving in the same brightness cases, LED1000 hours only 1 degree electricity consumption, normal bulb 17 hours 1 degree electricity consumption, ordinary energy-saving lamps 100 hours consumption 1 KWH. So long life LED super energy-saving lamps use theory life can reach thousands of hours above, normal bulb use life more than 1000 hours. So the light health light is not included in ultraviolet and infrared, no radiation, no pollution. Ordinary energy-saving fluorecent tubes and incandescent lamp light contains ultraviolet and infrared. So the green environmental protection does not contain mercury and lead such harmful elements, benefited from and recycling, and won't produce electromagnetic interference, ordinary tubes contained mercury and lead the harmful elements, such as energy-saving electronic ballast cause electromagnetic interference. So protect eyesight adopts dc power drive, no stroboscopic, common lights are ac drives, will inevitably produce stroboscopic for long time eyes adverse. So light high efficiency heat small, 90% of electric energy into visible light, and normal bulb only 20% is capable of converting from electrical to visible light, and the other 80% of converting from electrical to heat energy to limited resources is a kind of great waste. So high safety coefficient required voltage, current, produce less heat, no less safe hidden trouble, can be used in mines and other dangerous places. LED super energy-saving lamps gun are widely used in: (a), the courtyard, private garden, landscape lighting. (2) schools, hospitals, factories, lighting. (3) municipal lighting, bank, infrastructure, gymnasium, airport, cinema, industrial facilities, public health. (4) hotels, guesthouses, hotels, shopping malls, and cultural entertainment, business places. (5) advertising, exhibition, performance, site. (6) to rural power shortage region, in rural thrifty farmers often use 15-25W of incandescent lamp lighting, building new countryside "LED energy-saving lamps" rural especially huge market potential. Most lamps and lanterns belong to electrical products, in order to ensure the safe, lamps and lanterns must employ after purchase qualified electrician technician installation, please do not optional remove lamps and lanterns, partial lamps and lanterns accessories, no installation instructions Our offer after-sale service to the customers in the receiving goods within 48 hours, even once signed discover commodity has damaged situation, our factory follows the principle of good faith management principle, also responsible for free exchange. But the commodity returns to buyers cost contractor. Specific conditions in the premise of specific consult treat. Anyway, we will try our best to provide our customers providing after-sales service.
