e efficient - LED light bulbs use only 2-17 watts of electricity (1/3rd to 1/30th of

Incandescent or CFL). LED bulbs used in fixtures inside the home save electricity, remain cool
and save money on replacement costs since LED bulbs last so long. Small LED flashlight bulbs
will extend battery life 10 to 15 times longer than with incandescent bulbs.

Cost-effective - although LEDs are initially expensive, the cost is recouped over time and in

battery savings. LED bulb use was first adopted commercially, where maintenance and
replacement costs are expensive. But the cost of new LED bulbs has gone down considerably
in the last few years. and are continuing to go down. Today, there are many new LED light
bulbs for use in the home, and the cost is becoming less of an issue

Light for remote areas and portable generators - because of the low power

requirement for LEDs, using solar panels becomes more practical and less expensive than
running an electric line or using a generator for lighting in remote or off-grid areas. LED light
bulbs are also ideal for use with small portable generators which homeowners use for backup
power in emergencies.
Energy Sustainability begins with conservation and energy savings LED Lighting applications
will reduce wasteful energy by 50%-90% compared to other conventional lighting products.
Unlike traditional lighting products, LEDs do not contain Mercury, a potentially hazardous
substance that poses a threat of environmental damage. LED Lights not only consume a fraction
of the energy consumed by traditional lighting, it provides a double benefit of being longer
lasting and environmentally friendly. LEDs are highly rugged and feature no filament that can
be damaged due to shock and vibrations. The operational life of LEDs last 4 to 40 times longer
than traditional lighting products, while maintaining consistent light output over life. The key
strength of LED lighting is reduced power consumption. LEDs approach 80% efficiency; which
means 80% of the electrical energy is converted into light energy. LED allows for more
precise, purposeful light and reflects properties otherwise unseen, while providing improved
uniformity and visibility. While the initial cost of LED lights is higher, cost savings of LED
occurs over time by taking advantage of their longevity. Conventional lighting products true
cost is the enormous maintenance cost.
