The continuing advances worldwide of cost effective and eco friendly residential lighting continues to offer homeowners as well as business owners new choices. As energy costs continue to increase and cost consumers large amounts of money, new innovations such as LED lighting come to the marketplace to offer us a glimmer of hope. As far as home and office lighting is concerned, new strides are being made not only in energy efficiency, but in bulb life as well. There are the endless benefits to LED lighting, some of which we'll over in this article.
Lighting - An Overview
The first modern type lighting breakthrough came the form of an incandescent bulb, invented by the great Thomas Edison. Since that invention, incandescent lighting is still one of the most common forms of home lighting today. Fluorescent lighting brought an incredible improvement to the residential marketplace when introduced. It literally transformed kitchens and bathrooms but there were still considerable areas of improvement needed. LEDCentral.com.au is working toward moving homes and offices to a more efficient and eco friendly lighting source, the LED.
Other Energy Efficient Choices Illuminating the Home
The introduction of compact fluorescent bulbs expanded the possibilities for efficient home lighting even further.
From here low voltage lighting started appearing in exterior applications such as landscaping. The obvious migration and inclusion to home interiors was inevitable. Halogen bulbs showed promise as far as an attractive light source, but they proved very problematic for some applications. They generate far too much heat and are very fragile as well as being very uneconomical to run across an entire household or office. The time had come for the LED light bulb!
What is an LED Light Bulb?
An LED (Light Emitting Diode) light bulb is actually a cluster of individual units. Many of these produce white light but others generate light of other wavelengths and colours, even green, red and blue. The exact combination yields the desired light tone.
This modern lighting falls into the SSL lighting category (Solid State Lighting). This simply means that the light seen is emitted from a solid object, rather than a vacuum or a gas.
The Specific Benefits of LED Light
- Energy efficiency – The light bulbs burn very cool, while incandescent bulbs emit 98 per cent of their energy as heat! Much more bang for the buck.
- Long life – These lights can last from 50,000 to 100,000 hours. Incandescent light bulbs typically last around 1,000 hours and fluorescents are good for roughly 10,000 hours.
- Rugged durability – LED lights have no fragile filament to contend with, and no fragile tube. They are resistant to heat, cold, and shock.
- Lumens per watt – While manufacturers are still finding new ways to increase this ratio, Cree Inc. has been able to produce an LED bulb that generates 131 lumens/watt. This is research, though. Today's available LEDs are the same as compact florescent bulbs, averaging around 55. Incandescent bulbs wander sadly in at about 15.
Installation of LED Lights
LED lighting is compatible with almost all light housing and connection systems. Some models screw in such as the E27 connection type, replacing incandescents. Others, such as LEDCentral.com.au's range of LED Lights directly replace halogen MR16 and GU10 bulbs. LED lights have been specifically designed to be a halogen replacement globe, so home owners can easily switch them out to start seeing the benefits straight away.
The most common two connections in housing today are GU10 and MR16 connector types. All MR16 type globes use transformers, usually one per light. Specific DC constant current LED drivers should be used to gain the maximum life from LED globes.
