More and more energy saving and healthy environment (office) are installed by EOC's 5W LED MR-16 lamps with 2800K, globally.
Many people are asking if the LED lights are bright enough to replace the traditional lights, especially for the 4.2W LED MR-16 whose power consumption is only 1/12 of traditional 50W halogen lamp. As soon as EOC's 4.2W/2800K MR-16, which is dazzlingless design, were installed for the office lighting (as following photos) in Taipei, it is proved that EOC's new 4.2W MR-16 is not only 2 times brighter that other LED MR-16 providers but also able to replace the traditional 50W halogen lamp to save 12 times energy.
The following photos are one of the office in Taipei, whose light source is all LED lights from Excellent Opto. including 4.2W LED MR-16, 20W ceiling lights and 10W~60W LED light bar. It is a healthy environment, because all lights are LED lights that have no heat/infrared rays (IR) from the traditional 50W halogen lamps and tungsten filament lights , no ultraviolet (UV) from fluorescent lamp, no electromagnetic wave from the ballast and no flash to make your eyes be un-comfortable. However, how much money/energy will be saved if you replace the traditional lamps with LED lights ?
The above compare table is a example that is based on Taiwan power bill and assume 100 sets of EOC's 4.2W LED MR-16 to replace 100 sets of traditional 50W halogen lamps.
