Energy Saving Light Bulb Technologies
Invented by Thomas Edison, the light bulb literally started illuminating people's lives in 1879 with the flick of a switch. It has remained largely unchanged until recent times with the introduction of new technologies namely the halogen bulb, compact fluorescent lamp (CFL) and energy efficient LED bulbs. Lighting has become far more sophisticated with the range of control systems that are now available, giving the ability to make a more significant contribution to the overall effect of your interior design layout.
Energy Saving Light bulbs became essential to lighting homes and commercial buildings, which they have been doing for over 100 years. Technological advancement and environment pressure spurred the introduction of energy saving lights. First produced in fluorescent tubes, the technology has been developed to ensure it is suitable for a range of different uses and purposes. CFL became the first energy saving technology, and it has been advanced to ensure the bulbs are flicker free and reach a good level of brightness which wasn't the case when they were first in production and use. Their appearance has also improved and their size has become more appropriate.
Halogen bulbs were first launched onto the market by GE in 1958. Light is produced through the combination of tungsten filament and the iodine of bromide elements. Halogen's produce a very clear, bright and white light which the automobile industry has taken full advantage of as they use halogens extensively. The technology has advanced more recently to allow the creation of commercial lights for high voltage mains electricity for use in homes and commercial buildings, saving approximately 30%. The most recent lighting technology is LED's (Light Emitting Diodes) which was introduced in 1962. They were only low intensity red lights in their earliest form, but have advanced with technology and can now emit light colours across the visible spectrum. They are becoming brighter as technology advances and they represent the energy saving light bulb technology of the future.
The LED bulb uses Light-Emitting-Diode technology which has advanced in leaps and bounds in recent times and these energy saving bulbs come on instantly and do not suffer from reduced life span with repeated switching. The halogen bulb will save 30% in electricity, the CFL around 80% and the LED typically about 90% when compared to the traditional light bulbs. The other technologies and metal halide and sodium discharge lamps but one thing of for sure, that over the next decade the energy saving LED bulb will take over as the preferred technology.
