The replacement to CFL’s
LED light bulbs are slowly replacing CFL’s (Compact Fluorescent Lights) which are an intermediate solution to energy-efficient lighting. The reason LEDs have not yet displaced CFLs from the market are twofold: the first generation LED bulbs had a narrow and focused light beam, and the cost of the LED bulbs was too high. Recent developments in LED technology, however, have been addressing these issues. LEDs have been ‘clustered’ to provide more light, and mounted within diffuser lenses which spread the light across a wider area. Recent advancements in manufacturing technology have driven the prices down to a level where LED bulbs are more cost-effective than CFLs or incandescent bulbs.
LED’s generally offer lower energy consumption, longer life and increased robustness when compared to fluorescent lighting. Apart from general building lighting requirements, their high concentration of light make them well suited for niche applications like lighting of high productivity work areas or security lighting.
LED’s are now also available in tube form. They essentially replace T5, T8 and T12 fluorescent tubes and fit directly into most fluorescent fixtures. LED tubes provide light outputs comparable to or better than fluorescent and deliver the immediate benefits of high quality white-LED lighting. Other benefits include longer life, high efficiency, no mercury, no flickering, and no buzzing and instant start.
