LED lighting has been growing in popularity over time thanks to its various advantages over incandescent lighting and CFL lighting. It also has the distinction of being the most eco-friendly form of lighting and in our current age the importance of LED lighting grows by the day.
Power consumption: LEDs consume less power per unit of light (lumen) emitted than the rest of the field. They are more energy efficient than their competition. This means that a greater portion of their energy is converted to light and a smaller amount is wasted as heat when compared to traditional lighting and CFL lighting. Most LEDs convert 80-90% of their energy to light and waste the rest as heat while incandescent bulbs only convert 20% of their energy to light and the remainder to heat.
LEDs also require lesser power to function than incandescent lighting and CFL lighting. LED lights contain no toxic chemicals whatsoever and most of them are 100% recyclable. This in contrast to CFLs which contain harmful chemicals such as mercury. This in turn would pollute the environment in a greater manner when it is sitting in a landfill when compared to LEDs.
Lifespan of LEDs: LEDs have a longer lifespan than incandescent lights and CFLs. Hence, they have lower carbon emissions than both traditional lights and CFLs. For example, a 6-8W LED bulb, a 60W incandescent bulb, and a 13-15W CFL bulb each use 800 lumens. The LED will have an average lifespan of 30,000-50,000 hours while the CFL will have a lifespan of 8000 hours and the incandescent bulb will last for a mere 1200 hours. The same LED bulb uses about a tenth of the electricity that the incandescent bulb uses and about half of what the CFL bulb uses. Also, the LED bulb's carbon emission is about a tenth of the incandescent bulb's and lesser than half of what the CFL emits. Hence, fewer replacements are required for LEDs, saving resources and materials. This also saves energy and money in the manufacturing and production process.
What stops most people and businesses from using LEDs at this moment is the initial installation cost as the alternatives are cheaper. However, an LED bulb repays its cost with savings on replacements and the amount of electricity required. But most importantly, LED bulbs pave the way to a greener future.
