Pros of using LED bulbs
Long-lasting - LED bulbs last 10 times as long as compact fluorescents, and 133 times longer than typical incandescents.
LED bulbs and diodes have an outstanding operational life time expectation of up to 100.000 hours.
This equals 11 years of continuous operation. If you leave a LED light on for 8 hours a day, it would take around 20 years before you’d have to replace the LED bulb.
Durable - Since LEDs do not have a filament, they are not damaged under circumstances when a regular incandescent bulb would be broken.
Because they are solid, LED bulbs hold up well to jarring and bumping. LED lights are resistant to shock, vibrations and external impacts,
they make great outdoor lighting systems for rough conditions and exposure to weather, wind, rain or even external vandalism,
traffic related public exposure and construction or manufacturing sites.
Cool - these bulbs do not heat up; LED's produce 3.4 btu's/hour, compared to 85 for incandescent bulbs.
Energy-saving - LED's use a fraction of the wattage of incandescent bulbs. Batteries will last
10 to 15 times longer than with incandescent bulbs. Also, because these bulbs last for years,
energy is saved in maintenance and replacement costs. Many cities in the country are replacing their
incandescent traffic lights with LED arrays because the electricity costs can be reduced by 80% or more.
If you use traditional lighting and have an electricity bill of say $100 USD, then 80% of that money has been used to heat the room, not to light it!
Using LED illumination with 80% efficiency, the electricity costs would be around $20 and you’d have saved around $80!
Light for remote areas - because of the low power requirement for LED's, using solar panels
becomes more practical and less expensive than running an electric line or using a generator.
