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, while a ca. 20% is lost and converted into other forms of energy such as heat.With traditional incandescent light bulbs who operate at 20% energy efficiency only, a 80% of the electricity is lost as heat.
Imagine the following scenario:
If you use traditional lighting and have an electricity bill of $100, then $80 of that money has been used to heat the room, not to light it! Using LED illumination with 80% efficiency, the electricity costs would be around $20 and you’d have saved around $80.
The long operational life time acts as a multiplicator and helps achieve even more energy efficiency, especially large scale and when thinking in terms of urban infrastructure projects, such as cities, railroads and airports.
Think of e.g an airport using energy efficient LED lighting exclusively and achieving a 30% power consumption reduction in comparison with an airport using conventional lighting technology.
Because of the long life span of LED lights and virtually maintenance-free – think of all the work and energy it would take to purchase, stock and change the conventional light bulbs of an airport – you’ll see that you can make significant energy savings also when it comes to maintenance and replacement due to the long operational life times of LED lighting.
Since LED Lights do NOT overheat, electricity bills from air conditioning and fan usage will greatly diminish. A low-voltage power supply is sufficient for LED illumination. This makes it easy to use LED lighting also in outdoor settings, by connecting an external solar-energy source and is a big advantage when it comes to using LED technology in remote or rural areas.
LED lights are extremely durable and built with sturdy components that are highly rugged and can withstand even the roughest conditions.
Because LED lights are resistant to shock, vibrations and external impacts, they make great outdoor lighting systems for rough conditions and exposure to weather, wind, rain or even external vandalism, traffic related public exposure and construction or manufacturing sites.
Long lifespan stands out as the number one benefit of LED lights. LED bulbs and diodes have an outstanding operational life time expectation of up to 50,000 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 8 hours per day it would take around 20 years before you’d have to replace the LED bulb.
LED’s are different to standard lighting: They don’t really burn out and stop working like a standard light, moreover the lighting diodes emit lower output levels over a very long period of time and become less bright.
