LED light sources last longer, avoiding the hassle of frequent changing of light bulbs. This significantly reduces waste but also saves money in the long term energy saving.
In comparison to traditional lighting solutions, LEDs have very high efficiency because to produce the same light output, the energy consumption is very low in case of LEDs. LED lights are up to 80% more efficient than traditional lighting such as fluorescent and incandescent lights as 95% of the energy in LEDs is converted into light and only 5% is wasted as heat. Hence, low energy usage is a relief not just to us but the environment too!
On contrary to general lighting systems and CFLs, LEDs radiate very little heat in the form of IR that can cause damage to objects or fabrics.
CFLs contain mercury which if not handled or disposed of properly, CFLs can contaminate air and water supply as well as landfills with deadly compounds. Disposal has to be arranged through a registered waste carrier so switching to LED avoids the cost and time implications required for disposal and helps to protect the environment from further toxic waste.
LEDs, unlike quite a few conventional light sources, light up instantly and take only a few microseconds to achieve full brightness.
Point source form of LEDs ensure proper control of light distribution with the help of secondary optics like lenses and diffuser.
Colour Rendering Index is a measure of a light source's ability to show object colors, "realistically" or "naturally", compared to a familiar reference source, either incandescent light or daylight. The excellent colour rendering properties of LEDs is owed to technological advancements.
