If we take the average energy budget into consideration, it has been find out that the electric lighting burns up to 25% of the total energy. Now throwing some light over the bounty of energy losses and bundles of electricity bills, the electricity used over the lifetime of single incandescent bulbs/lamps costs 5 to 10 times the original purchase price of the bulb itself.
LED (Light Emitting Diode)
The revolutionize walk-in of the Light Emitting Diode (LED) & Compact Fluorescent Lights (CFL) have come up with the highest energy-efficient lighting. The price of LED bulbs is going down each year as the manufacturing technology continues to improvise. LED technology is advancing rapidly out doing all others like CFLs and incandescent lamps. When LEDs debuted in the electronics market, it was limited to single-bulb usage in applications. But the satisfactory results, cost effectiveness and energy efficiency outcomes have made the demands to escalate. Manufactures have expanded the applications of LEDs by clustering the small bulbs. Now-a-days, LED is also reaching the home lighting applications as well.
LEDs are now stepping into the age of becoming the standard for all lighting needs. LED bulbs last up to 10 times as long as compact fluorescent and far longer than typical incandescent. In terms of durability also, LEDs are yielding best results.
- As LEDs do not have a filament, they do not get damaged under abrupt circumstances where regular incandescent lamps would be broken. It do not cause heating problems as LEDs produce 3.4 btu’s/hour compared to 85 for incandescent bulbs. This has curtailed the air conditioning costs in the home to a much extent.
- As far as the hazardous/poisonous material is concerned no mercury is used in the manufacturing of LEDs.
- LED light bulb uses only 2-17W of electricity which is 1/3rd to 1/30th of Incandescent or CFL. LED bulbs used in fixtures inside the home save electricity, remain cool and save a lot of money which is uselessly spent on replacements as LED bulbs last for long.
- Small LED flashlight bulbs will extend battery life 10 to 15 times longer than with incandescent bulbs. Over the last few years, the cost of LEDs has gone down to a larger extent meeting its demands.
Leading to ample of innovations and advancements in LEDs, variety of LEDs are in the market such as diffused LED bulbs, dimmable globe LED bulbs, flood reflector LED bulbs, flame tip candelabra LEDs, LED tube lights and many more.
CFL (Compact Fluorescent Lamp)
Coming on to the effectiveness and better energy-efficient results, CFLs are 4 times efficient and last up to 10 times longer than incandescent. A 22W CFL has about the same light output as a 100W incandescent. CFLs use 50-80% energy than incandescent. Although initially more expensive, you can save money in the long run because CFLs use only 1/3rd the electricity and last up to 10 times as long as incandescent. A single 18W CFL used in place of 75W incandescent will save 570W over its lifetime. CFLs can be applied nearly anywhere replacing incandescent lamps. Energy-efficient CFLs can be used in recessed fixtures, table lamps, track lighting, ceiling fixtures and porch lights.
