 Material: Extruded aluminum (polished, smooth appearance, heat resistant to damage by oxidation color light) Lamp: E27 E14, GU10, MR16 life: 50000H warranty: three years, the material of the product beautiful, graceful lines, good heat dissipation constant current source driver, Puri chip packaging high-power light source, brightness, stable performance, soft lighting, long life, widely used in walls or ceilings of hotels, guesthouses, halls, clubs, villas and other high-end places to lighting and decorative 



 High pressure sodium lamps are widely used in roads, tunnels and factory lighting, high pressure sodium lamps present a slow start, strobe intensity, low power consumption, temperature and pressure, noise, headlight shortcomings. Metal halide lamp has good luminous efficiency, has been widely used in factories, shopping malls, city lighting, road lighting, sports venues and other metal halide lamp; but the prevalence of short life, low power consumption, the lights also flicker and glare, the power with voltage fluctuation, a slow start, giving users a lot of trouble. LED (Light Emitting Diode) light-emitting diode, the LED for short, is an ability to convert electrical energy into visible light solid-state semiconductor devices, which can be directly to the electricity into light. The semiconductor chip consists of two parts, the part of the P-type semiconductor, the dominant hole in it, the other end of the N-type semiconductor, here is mainly electronic. But the two semiconductor connected, they form a PN junction. When the current through the wire to the chip, the electrons would be pushed to the P region in the P region electron-hole recombination, issued in the form of photon energy. High energy: low-voltage DC drive, ultra low power consumption, electro-optical power conversion of 95% or more, over the same lighting effects than traditional energy sources 80%. Luminous efficiency reach 120lm / W, 3% / 8000 hours, the light fades. (2) long life: the LED cold light source for the solid epoxy resin, no filament the luminous difficult to burn, thermal deposition and disadvantages. Low working voltage, the service life of up to 50,000 to 100,000 hours, more than 5 times longer life than traditional light sources. Small glare, no radiation, mercury element, not to issue the use of hazardous substances. My company R & D and production of high-power LED lights, 60,000 hours of ultra-high-life, special power, high light efficiency, high color, no flicker, instant start start, maintenance-free, a lot of advantages. LED lights will completely replace the high pressure sodium, metal halide place applications. [Cost comparison chart
