IPH Electrical whenever possible will always use low energy lighting options to help the environment but also to help our customers save money, so, what makes low energy light more efficient and are they worth the investment?
LED Lighting is the most energy efficient lighting available in the market. The operational life of current white LED lamps is 100,000 hours. This is 11 years of continuous operation, or 22 years of 50% operation. The long operational life of a led lamp is a stark contrast to the average life of an incandescent fitting, which is approximately 5000 hours. If the lighting device needs to be embedded into a very inaccessible place, using LEDs would virtually eliminate the need for routine replacement.
The type of fitting we commonly think of as a low energy light is a compact fluorescent lamp, Traditional and halogen fittings contain a filament of resistive wire that gets so hot when an electric current passes through it that it glows, giving off light. Both kinds are filled with an inert gas to stop the filament catching fire. Both traditional and halogen lights convert around 2.5% of the electricity passing through them to light, with 97.5% being wasted as heat.
Low energy compact fluorescent lights (CFL) are coated on the inside with fluorite and are filled with mercury vapour. When elements inside the fitting heat the vapour, it gives off UV light which causes the fluorite to give off visible light. Because they work in this way, low energy lights give off around 10% light and 90% heat, which sounds like a small difference compared with conventional types but actually means that these are 4 times more efficient. Because CFL lights convert more electricity to light, this means that they need less electricity going through them in the first place to produce the same amount of light as a conventional lamp.
There is no comparison between the cost of LED lights vs. traditional incandescent options. With incandescent lamps, the true cost is the cost of replacement and the labour expense and time needed to replace them. These are significant factors, especially where there are a large number installed. For office buildings and skyscrapers, maintenance costs to replace lamps can be enormous. These issues can all be virtually eliminated with the LED option. The key strength of LED lighting is reduced power consumption. When designed properly, an LED circuit will approach 80% efficiency, which means 80% of the electrical energy is converted to light energy. The remaining 20% is lost as heat energy. Compare that with incandescent options the energy and money saving is a huge benefit to all.
Various lighting options are available such as LED Strip, LED Fittings, LED replacement lamps, colour changing LED. This type of lighting is perfect for schools and other commercial buildings where the lighting is constantly on.
