>>Frequently Asked Questions

LED's are extremely energy efficient and consume up to 90% less power than incandescent bulbs. Since LEDs use only a fraction of the energy of an incandescent light bulb there is a dramatic decrease in power costs. Also, money and energy is saved in maintenance and replacement costs due to the long LED lifespan.Because of the low power usage of the LEDs they are becoming extremely popular for light sources in remote areas that use solar panels. LEDs do have a higher initial cost than incandescent and compact fluorescent light bulbs, but the cost is quickly recouped over time in lower electricity costs.
LEDs have a lifespan of up to 100,000 hours compared to the 1500 hours for incandescent bulbs. A LED lighting device can last up to 11 years under constant use. On average LED bulbs last up to 10 times as long as compact fluorescent bulbs and 133 times longer than typical incandescent bulbs. Long lifespan of LEDs will dramatically reduce maintenance costs and lower long-term operating costs to traditional incandescent and fluorescent tubes.
LED lighting devices are made from non toxic materials, unlike fluorescent lighting that uses mercury that may pose a danger to the environment. LEDs are also recyclable and considered "Green or Earth Friendly".
