FAQ About LEDs

FAQ About LEDs
1. What are LEDs? How do they work?
LED stands for Light-emitting diode. LEDs are small light sources that become illuminated by the movement of electrons through a semiconductor material.

2. Why are LED Lightings more expensive?
LED light bulbs use an actual circuit board to operate and are made of electronic components. Essentially, they could be considered as an electronic device. This technology continues to gain advantages almost daily. The manufacturing and supply/demand of general lighting products are gearing up today, and we will see costs continue to decline as the adoption rate of LED Lighting increases.

3. What are LED Lighting's advantages over other lightings, like fluorescent or incandescent lighting?
(1) LED Lights is more efficient, durable, versatile and resist shock and vibration.

(2) LEDs contain no mercury, and most LED lighting fixtures contain no lead.

(3) LEDs do not produce and shot of ultraviolet radiation which causes fabric fading, color fading in Art, carpeting and other soft goods.

(4) LED Lights have an unparalleled even spectrum of light and emit light in a specific direction, whereas an incandescent or fluorescent bulb emits light and heat in all directions.

(5) LED Lights have no gases, no filaments and no moving parts to fatigue, and there is none of the"Buzzing" or "flickering" that many people are sensitive to.

(6) LED Lights emit 90% less heat than a conventional bulb, therefore producing more light than heat and gaining maximum energy efficiency. LED light bulbs, always operating at a lower temperature than a CFL or incandescent, has immediate benefits in reduced cooling bills in the summer months where we are paying for our Air Conditioning to cool our offices

(7) LED lights have a life span beyond 50,000hrs, while Fluorescent/CFLs 6,000-8,000hrs and Incandescent only 1,000hrs.

4. Where are LED lights commonly used?
Residential and especially commercial and industrial plants, roads, stores, libraries, galleries, and warehouses can immediately benefit from LED Lighting.

5. How do I go about converting my facility to LED Lighting?
An LED lighting conversion usually includes three types of solutions:
(1) Complete replacement of the existing fixtures

(2) Retrofit of existing fixtures with LED components

(3) Simple plug-compatible bulb replacements

For each of these solutions, the existing wiring and power can often be used.

6. How to figure out the cost to convert the lighting in a building to LED lighting? How fast can we expect payback?
The business case is variable depending upon a number of factors applicable to each organization. Important variables include cost of electricity, maintenance, labor costs, new facility or retrofit, disposal costs for bulbs, etc. Some business cases can see payback in under a year, and some take longer to payback.
