Led Lighting: Advantages & Disadvantages
Led Lighting presents great advantages compare to more traditional Lighting sources.
One of the main advantages of LED luminaries is the Energy Efficiency. Use of this type of luminaries can generate an important saving in the electricity bill, reaching in some cases between 50% to 80% reduction of the electricity usage, albeit this will depend on the type of luminaries that being replaced.
Electricity utility bill reduced between 50-80%
In addition to the cost saving, the LED luminaries are also characterized by its high durability that can go from 15,000 Hours up to 50,000 Hours – depending on the type and quality of the LED -, maintaining close to 80% of its capacity towards the end of its life cycle, with the corresponding saving on both replacement and maintenance costs.
The above two characteristics "Energy Efficiency and Durability" means the return of investment (ROI) of a lighting project using LED luminaries technology is quite fast compare to more traditional installations. It is estimated the ROI will be achieved within 3 years thanks to the energy efficiency and corresponding utility bill cost savings.
From a technical point of view, LED Lighting technology improves considerably the efficiency of lighting devices, this mainly due to a) its High Colour Rendering Index (CRI) and b) its immediate booting, both of these characteristics help obtaining 100% of lighting flow from the very first moment, even in cold environments.
Another important fact to mention here is the high level of flexibility in the design, that brings the use of LED lighting technology. Currently there is a great variety in sizes and models of LEDs, as well as various options in the tonalities, regulation possibilities, RGB technology, etc…, all of these makes it easier to design and build lighting systems completely tailored to the specific needs of each project and environment.
Finally LED Luminaries also present various environmental advantages. Being more energy efficient means they produce less CO² emissions, they also not include mercury or any other heavy metals, they don’t emit infrared or ultraviolet radiation and generally help reducing light pollution because the light emitted by the LED luminaries is always directed.
One of the potential disadvantages will be the high exposure and sensibility of high temperatures. Normally from 65⁰C the majority of LED luminaries can start malfunctioning, therefore it is required to have a good heat dissipation surface, usually aluminium, in order to guarantee its durability.
The increasing demand for this type of lighting technology means there are a lot of companies now offering a variety of products. @PTI we recommend to avoid going for the cheapest, if you really want to obtain the benefits mentioned above, choose a good quality product, and a trusted supplier.
