electrodeless outdoor spot light 60,000hrs lifespan 3 years warranty 75% energy saving CE,ISO9001 approval the advantage of electrodeless discharge lamp: long life: No filament bulb without electrodes, using high-quality rare earth phosphor powder and anti-aging process. Life of up to 60,000 hours or more, the longest life of up to 15 years, is generally up to 6-8 years. Is 50 times the life of incandescent bulbs for more than an ordinary gas discharge lamp 10 times. Long life, once installed, the two exemptions: exemption from maintenance and management, eliminating the high maintenance costs. 2, energy-saving - Up to 75% High brightness: Mechanism of high-frequency electrodeless lamp emitting light under the Department of vacuum inert gas discharge, LED brightness is much higher than conventional gas discharge lamp. A high proportion of visible light: High-frequency electrodeless lamp in the visible light emitted by the ratio of up to 80%, so when tested with traditional illumination of instrument data, even if their data than the same environment of the high-power high-pressure sodium lamp, but the human eye's visual environmental effects are still over the latter. (Traditional illumination instrument contains a large amount of data generated by the non-visible light, including, but not visible light high-pressure sodium ratio is very high) Power Factor High: High-frequency electrodeless lamp power factor of up to 98%, non-reactive loss greatly reduced. This long application:This long life ceiling lamp is newly researched and developed by our company according to the markets needs for energy-conservation illumination.It is widely used for both indoor and outdoor floodlighting in various plants. picture shouws:
