Features and Benefits of U-Tron LEDs
1. The right product for the application. Today's LEDs output the illumination necessary to protect our streets, our sky, and our environment.
2. The LEAST costly alternative available today. LED Street Lights deliver the best economic return compared to conventional alternatives considering the total life-cycle costs including installation, maintenance and energy.
3. Consume less energy. Generally, a LED consumes less than 1.15 watts to operate. This low power consumption means you save on your energy costs.
4. No heat output, less CO2 pollution. LEDs can convert almost all the energy used into light, creating a highly efficient light source. In contrast, conventional lighting emits heat and/or light pollution.
5. Long lifetime. An LED can last for up to 100,000 hours. High Power LEDs can last up to 50,000 hours. In comparison the lifespan of an incandescent light is about 1,000 hours and for a halogen light is about 2,000 hours.
6. Environmentally safe. LEDs are made from non-toxic materials - unlike fluorescent lights which contain mercury. Plus they can also be recycled.
7. Durable. No loose or moving parts. They can withstand extreme temperatures and have a high Impact Resistance. Shock-proof since they have no filament and glass envelope - unlike traditional lamps.
8. Easy on the eyes. No Strobe - eliminates the visual fatigue which can be caused by the strobe effect of traditional street lamps
9. Dark-sky Friendly. Brings back the stars for us and for the other creatures of this planet.
10. No Cleaning Necessary. No burned insects accumulate on the surface, so no reduction of light intensity - unlike conventional lamps.
11. No Radiation. No ultraviolet or infer red emissions. LEDs only emit light in the visible spectrum.
