Nice One 5W LED LAMP ENERGY SAVING

LED lamps are now rapidly replacing conventional incandescent lamps and compact fluorescent lamps (CFLs) in domestic and commercial lighting. Understanding the data that is presented with respect to lamp performance and operating life is the key to making informed product choices

A very important characteristic to take into account when selecting an LED lamp is its colour rendering index (CRI). This describes how accurately the light from a lamp reproduces colours of various objects compared with an ideal or natural light source. In practice, a tungsten halogen lamp is considered to have a CRI of 100. LED lamps based on blue chips plus phosphors are now achieving CRI of approximately 80. A higher CRI is possible but only at the expense of lower efficiency. Anything lower than a CRI of 80 is likely to give a distorted view of the world with respect to colour and within the next year or two, LED lamps with CRI of up to 98 will be available. The colour rendering performance of these lamps will be virtually indistinguishable from that of natural light and will be achieved through the use of violet chip technology
