Technology Advantages of LED Lamps

Posted By editor On 19th August 2006 @ 08:24 In News | Comments Disabled

Solar Energy powered Digital LED lighting systems are clear winners in terms of luminosity, life span, power required, and costs, when compared to other lighting products.

Feature LED lamp with 42 LEDs Compact Fluorescent Lamp Incandescent lamp
LUMINOSITY
(150 Lumens) Power Used		 2.5W 5W 15W
Lifespan 40,000 hours and more 4000 hours 600 hours
Electricity Used/per Year 7.3 kilowatt-hours 14.6  kilowatt-hours 43.8  kilowatt-hours

Savings in electricity using LED lamps:

Yearly Usage LED Lamp Compact Fluorescent Lamp Incandescent lamp
Extra electricity used, over LED lamps 0 7.3 kilowatt-hours more per year 36.5 kilowatt-hours more per year
Cost of electricity, over LED lamps 0 Rs 45 more per year Rs 219 more per year
Unit replacement costs 0 Rs 90 per year Rs 60 per year
Total yearly costs, over LED lamps 0 Rs 135 per year Rs 279 per year

[Currency rate: US$1 = Rs 42, May 2007]

Benefits of LED lamps:

  • Long-lasting - LED bulbs last 10 times as long as compact fluorescents, and 50-100 times longer than typical incandescents in normal everyday use situations.
  • Durable - Since LEDs do not have a filament, they are not damaged under circumstances when a regular incandescent bulb or CFL would be broken. Because they are solid, LED bulbs hold up well to jarring and bumping. With CFLs, there is the added problem of mercury toxins spreading on breakage.
  • Cool - these bulbs do not cause heat build-up. LEDs produce 3.4 btus/hour, compared to 85 btus/hour for incandescent bulbs.
  • Energy-saving - LEDs use a fraction of the wattage of incandescent bulbs. These bulbs last for years, therefore energy is saved in maintenance and replacement costs. This also makes LEDs the best choice for use with alternative energy sources
