Led Lights Over Traditional Lighting: Advantages of LED Lights

The technology of light emitting diode (LED) lighting was a game changing invention in the past few years and helped mankind a lot in various ways. When compared to the traditional lighting and lights like the compact fluorescent lighting (CFL) or incandescent, LEDs are much more compact, easy to use and energy efficient too.

In these kinds of lights and bulbs, an electric current is being passed through a microchip which helps the tiny sources of the LEDs to illuminate and thus the result that you get is the illuminated visible light. At the same time, there is a heat sink that efficiently absorbs any excess heat that is being released. The various benefits of LEDs have been stated below.

Energy efficient lights

Quite low amounts of power are being consumed by these LEDs. The energy efficiency of these kinds of lights are being observed through two concepts- useful lumens and luminous efficacy. These units mainly state out the amount of light that is emitted per unit of watts. These LED Lights are proven to be 60 to 75% more energy efficient as it uses up more useful lumens and leaves after lesser lumen wastes. If you replace all the lights in your house or office with that of the LEDs, you can save up to 90%.

Longer lifespan

The lifespan of the LEDs are much superior to that of the incandescent. The lifespan of the traditional incandescent is almost around 1000 hours whereas the lifespan of LEDs are almost around 50000 hours. If used more efficiently it can also last for 1,00,000 hours, which indicates that it will last from 6 to 12 years; which is 40 times more than the traditional lights.


The LED lights are much more eco-friendly as they do not use any kind of mercury in their internal parts for the construction of these lights. The traditional lights, like mercury vapor lights, need special care to handle at the end of their life span and need proper disposal. But with the new gen LEDs, you will not have to think about their disposal as they are environment friendly and make of non-harmful materials.

No UV or heat emissions

Changing or touching an incandescent light bulb becomes impossible as it remains extremely hot due to the high amount of heat generated. These light bulbs convert 90% of the energy into heat and just 10% into light. On the contrary, the LEDs emit light that remains within your visible spectrum and almost no heat is generated. This is a big reason for why the doctors are even opting for such lights as a solution for the treatment of Seasonal Affective Disorder (SAD) that troubles people during the year’s darker months.

Flexible design

These kinds of lights can be easily used in various applications as they are quite small in size and combining a lot of them together in a circuit, a traditional bulb can be easily made. Like with a string of LED lights, you can easily make a Christmas line string. As the lights are so small, you can use them to light up things like your working desk to a stadium.

Great CRI levels

CRI or Color Rendering Index is the ability of the various kinds of lights to reveal the original color of objects when compared to the natural light. The LEDs have high levels of CRI and use white light, neither warm nor cool and reveals the objects as they are- without any monochromatic effects that occur in the case of traditional bulbs.

Solid State Lights

The LEDs are SSLs (solid state lights) which means there is unnecessary glass jar or convert around the light, like it used to be in the case of incandescent bulbs.

Instant turn on and off

You can easily turn on and turn off these LED lights instantly and do not have any warm-up time or period like that of the various metal halide lamps. At the same time, frequently switching on and off the lights will not lead to any kind of degradation or disruption in the quality or lifespan of the light.

These are some of the attractive features for which the LEDs are becoming the first choice for both the commercial and residential usage, like the lighting experts and facility operators. An estimation has been made by the Department of Energy that if by the year 2027, the various companies and institutions opts for LEDs, then there could be an electricity saving of around 348 terawatt-hours.
