COMPARISON BETWEEN LED, CFL & INCANDESCENT LAMP

The Household lighting cost typically accounts for 10% of the electric bill. Changing the light bulbs effectively can reduce the long-term energy costs significantly. The popularity of the fluorescent light can be judged by the fact that it accounts for a greater amount of light produced on our planet than any other light source. It secure this dominating position by the 1970s and today, it approximately accounts for about 80% of the world's artificial light. It is manufactured in almost any shade of white as well as colored versions. It also has an advantage of a low system cost, its lifetime is very long, it is fully dimmable and is easy to use, and above all it achieves high luminous efficiencies to yield a low cost of operation. In 1980, its position was further strengthened by the introduction of the compact fluorescent lamp. The traditional incandescent bulbs usually convert most of their energy into heat instead of light, leading to wastage of electricity on unnecessary warmth. Compact fluorescent lights (CFLs) and light emitting diodes (LEDs) on the other hand, convert most of their energy into light. But the frequent use of CFLs can shorten their life span. LEDs are designed to last longer than the average incandescent bulb and CFL, reducing both energy and replacement costs and increasing longevity. LED bulbs consume up to 80 percent less energy than their incandescent counterparts and 20 percent less than CFLs. They can last up to 25 times longer than CFLS and incandescent
