Energy Impact and Performance of Led Encastrable

According to statistics reported by the end of 2007, approximately 800 million led encastrable downlights had been installed in commercial and residential buildings in the United States. Before then, incandescent lamps had been the predominant source of light installed in buildings all over.

The annual consumption of electricity as at that time had been reported to be outrageous. There was great likelihood for an energy shortage, which could lead to national disaster. That was when it was suggested that energy consumption could be reduced by 877 TBtu if led encastrable fittings were installed in approximately 6.7 million homes in the U.S. That would mean that these devices could offer an efficiency of roughly 61 Im/W.

Now, there are much improved models of led encastrable down lights available in the market. Some even exceed 80 Im/W, offering much more energy conservation than was initially predicted.

When omnidirectional lamps are installed, it limits the efficiency of these downlights by as much as 50%. That’s because the light emitted gets trapped in the luminaire. Therefore, it is clear enough that the optical system included in the design of these lamps plays an important role. They can increase the distribution of the light and mitigate the glare to improve orientation.

That is to say that the color, diffusion and specular orientation of the optical system can make emission of the light horizontal, vertical or angled. The directional led encastrable lamps can be more efficient because they have a modular lamp luminaire system installed in them. They therefore offer greater efficiency.

Performance of Led Encastrable

There is a wide variety of led encastrable down lights available in the market. However, understanding the performance of these light fittings can be rather misleading. There are particular characteristics of the LED lamp that influence the performance. Some observations worth mentioning with regards to performance include:

The Lumen Output: This represents the range of output. It can be described as “substantial,” with production of less than 2000 lumens (output efficiency). This may work as good as the incandescent lamps, but is not up to the wattage provided by halide lamps. This means it saves a lot of energy and produces fluorescent light.

Luminous Efficiency: These lamps or downlights have better efficacy than conventional downlights. This is because they have proved to reduce consumption by 80 Im/W. According to the approved efficiency by ENERGY STAR®, downlights approved as conservation lamps should have an efficiency of about 42 Im/W. Led encastrable lamps exceed this expectation, which makes them better than other lamps.

Luminous Intensity Distribution: There are two forms of led encastrable lamps – the retrofit units and the integrated ones. Integrated ones offer more variety in terms of luminous intensity distribution. One can find those with narrow or wide distribution of light.

Color Characteristics: Led encastrable lamps have what is known as the “color rendering index” (or CRI should be greater than 80) and the “correlated color temperature” (or CCT should be between 2700 and 4100).

Cost and Lifespan: Led encastrable lamps are affordable and have a long useful life. They are cost effective because they last for as much as 5 years.
