March 24 – Buy Energy-Saving Lightbulbs

“The girls who were wise answered, ‘There’s not enough oil for all of us!'” ~ Matthew 25:9


Everyone or rather all buildings are dependent on light bulbs, individually light bulbs are not major energy consumers in building but when considered collectively, they use a significant amount of energy. Lightbulb manufacturing has been undergoing an energy-saving revolution in the recent years. There are 3 types of lightbulbs, namely; Incandescent light bulbs; Compact florescent lights (CFLs) and Light-Emitting Diodes (LEDs). LEDs are the most advanced lightning technology on the market.  LEDs are the most energy efficient lightbulbs available on the market and they also have a considerably longer lifespan.

Advantages of using energy saver bulbs(LED):

Energy efficient- LED lights are up to 80% more efficient than traditional lighting such as fluorescent and incandescent lights. 95% of the energy in LEDs is converted into light and only 5% is wasted as heat. This is compared to fluorescent lights which convert 95% of energy to heat and only 5% into light! LED lights use much less power than traditional lighting; a typical 84 watt fluorescent can be replaced by a 36 watt LED to give the same level of light. Less energy use reduces the demand from power plants and decreases greenhouse gas emissions.

No toxic elements- LED lights contain no toxic elements. Compact Fluorescent lights contain noxious chemicals such as mercury. These elements contaminate the environment when disposed of in landfill waste.  LED bulbs helps to protect the environment from further toxic waste.

Less lights needed- LEDs have a better quality of light distribution and focus light in one direction as opposed to other types of lighting which waste energy by emitting light in all directions, often illuminating areas where light isn’t required. Less LED lights are needed to achieve the same level of brightness given off by fluorescents and incandescent lights. Fewer lights will reduce energy consumption and will therefore be a benefit to the environment.

Life span- LED Lights last up to six times longer than other types of lights, reducing the requirement for frequent replacements and therefore decreasing the resources needed to manufacture lightbulbs. A longer life span will result in lower carbon emissions.
