What are the advantages of LED?
LED lighting systems have a much longer lifetime than conventional lighting and can be up to 100.000 hours. This is 11 years of continuous operation, or 22 years of 50% operation. If you leave on the LED fixture for 8h per day it would take around 20 years before you’d have to replace the LED bulb.
Reduced Energy consumption.
LED is the most efficient way of illumination and lighting, with an estimated energy efficiency of 80%-90% when compared to traditional lighting and conventional light bulbs. This means that about 80% of the electrical energy is converted to light, whilst conventional lighting systems lose 80% as heat given off (wasted).
This means that if for example you had an electricity bill of £100.00, with non LED lighting £80.00 of the total bill is being wasted as heat not light. Using LED illumination with 80% efficiency, the electricity costs would be reduced to around £20.00 with a saving of around £80.00
The long operational life time increases this saving as LED performance does not reduce but energy costs do rise.
For larger scale projects such as offices, schools, small or large business and Universities LED lighting equates to excellent cost effectiveness.
For example a business using energy efficient LED lighting exclusively and achieving a 30% power consumption reduction in comparison with a business using conventional lighting technology, immediately has a bill saving of minimum 30%.
Additional savings when using LED arise from the cost of maintenance work and the replacement of bulbs.
How Environmentally is LED?
LED lights are free of toxic chemicals however conventional fluorescent lighting bulbs contain a multitude of materials like e.g mercury that are dangerous for the environment or for the home or business owners if a bulb is broken.
How durable are LEDs?
LEDs are extremely durable and built with sturdy components that are incredibly rugged and can are suitable for use in the harshest of environments and conditions.
Because LED lights are shock resistant, and are able to withstand external impacts, they are ideal for outdoor lighting systems that are exposed to weather, wind, rain and even external vandalism.
Do LEDs emit UV ?
LED illumination produces little infrared light and virtually no UV emissions.
This is important as both of these can degrade or harm goods and materials.
LED is the ideal solution for illuminating UV sensitive objects or materials such as in museums and art galleries.
LED mood illumination is already being used in airplanes, classrooms, vehicles and we can expect to see a lot more LED mood illumination in our daily lives within the next few years.
Can LED withstand cold or hot temperatures?
LEDs are ideal for operation under cold and low outdoor or indoor temperature such as outdoor winter lights, freezer rooms etc.. By contrast with fluorescent lamps, low temperatures may affect operation and cause system failure,
Can LEDs be focused on specific points like spotlights ?
Do air source heat pumps need a lot of maintenance?
Do LEDs provide instant lighting?
In addition, LED lights can be switched off and on frequently without affecting the LED’s lifetime or light emission. In contrast, traditional lighting may take several seconds to reach full brightness, and frequent on/off switching drastically reduces operational life expectancy resulting in extra cost.
Can LEDs be used in areas of low voltage?
Yes low-voltage power supply is sufficient for LED illumination meaning that LED can be designed for use in almost any situation.
Can LEDs be used in conjunction with Solar power?
Yes ,due to their ability to operate in low voltage supply areas its easy to use LED lighting in outdoor or indoor settings, by connecting an external solar-energy source and when it comes to using LED technology in remote or rural areas LED provides a clean, crisp, low cost and energy efficient solution.
How much does LED cost?
Whilst the initial cost of installing LEDs is more than conventional lighting, these extra costs can be easily and quickly recouped once the system is up and running for instance a building running 300 lights can save around £7400.00 (based on current energy prices) per annum and off course energy costs will rise.
