the efficient light

Consuming only 10 to 20% of the power required by traditional light sources, LEDs are very energy efficient. For instance, a traffic light using an incandescent light bulb requires 150W, using LEDs would instead reduce the energy consumption to 10W. This not only brings substantial energy cost savings, but also reduces the environmental impact of artificial lighting.
In contrast to conventional light bulbs which generally expire after 5,000 hours, the lifetime of LEDs ranges from 35,000 to more than 100,000 hours - this is equal to 4 to 12 years of continuous operation. Consequently, replacement costs of LEDs are reduced to a minimum for the customer.

Because of its construction LEDs are very durable; while regular light sources are very fragile and sensitive to shocks and vibrations, the LEDs' encasement in high strength optical grade resin makes the lights highly resistant to outside influences. This robustness in turn significantly reduces maintenance costs and makes LEDs extremely suitable for hard-to-reach and outdoor installations.

With their energy efficiency, long lifetime, and high durability, LEDs not only operate on an eco-friendly basis, but reduce maintenance costs significantly. Despite the fact that the initial cost of LED bulbs is higher than that of incandescent or halogen lighting, the long term savings pay off.
