FAQ

• Q- How to calculate replacement solution between tranditional laps and LED?

  A- 　　Replacement solution between tranditional lamps and LED 　　Many people mention "efficiency" of LED lights when discussing their output per Watt. The correct term is "efficacy" because we are dealing with power in (Watts) vs. Luminous Flux out(Lumens). 　　In any case, the higher the efficacy the more light we are getting for the energy we are using. Cool White LEDs have a higher efficacy than Warm White LEDs, because the Warm White LEDs use more phosphors, which absorb and re-emit the light in a warmer wavelength. 　　Efficacies of various light-sources are shown below: Bulb Type Luminous Efficacy Incandescent lamps 5 lm/w Halogen lamps 10 lm/w Fluorescent lamps 40 lm/w Metal Halide lamps 50 lm/w LED with warm White 85 lm/w LED with Cool White 90 lm/w 　　So if you want to replace tranditional lamps, please care about total lumens of lamps. 　　for example,if you want to replace 70w Halogen lamps,you can choose 7w led with cool white or 8w led with warm white.

• Q- Are LEDs affected by extreme conditions?

  A- 　　LEDs are geared for harsh environments. LEDs function from -40F to 180F. There is no delay or required "warm up time" for LEDs to function.

• Q- Why we choose LED lighting?

  A- 　　Replacing incandescent bulbs with eco-lighting products is a simple and effective way to slow down global warming while saving energy and money. A 20W LED produces a similar amount of light to a 100W incandescent bulb but consumes 80% less energy. 　　LEDs are Efficient 　　When an incandescent bulb is lit, about 90% energy is converted to heat instead of visible light, making it very energy inefficient. 　　LED Lamps use light-emitting diodes as the source of light. They can also save up to 80% electricity compared to traditional halogen lamps. 　　In general, LEDs can generate the same level of lumen with 20% of the electricity used by their incandescent or halogen counterparts. To make it easier for the public to select the true energy efficient products, many countries and regions have implemented energy efficiency policies and introduced mandatory or voluntary labelling systems to provide information on energy consumption and efficiency to help consumers make better purchasing decisions. 　　LEDs are Economical 　　LEDs are cost efficient as well. While saving you up to 80% of electricity costs, they further save you maintenance costs with their high illumination performance, prolonged lamp life and durability. 　　It is estimated that if every American home replaced just one incandescent light bulb with an energy saving lamp, the energy saved would be enough to light more than 3 million homes for a year. In addition, more than USD600 million in annual energy costs would be saved with a reduction in greenhouse gas emissions equivalent to more than 800,000 cars. 　　LEDs are Widely Applicable 　　LEDs are now available in different sizes, shapes, colour temperatures and features, providing more options to consumers for home and commercial use.
