Use energy efficient light bulbs in your home!

Use energy efficient light bulbs! By using energy efficient light bulbs, you can light your home with the same amount of light while spending less money. Lighting accounts for about 15% of an average home’s electricity use, and using LED lighting saves the average household about $225 in energy costs per year. 

So one of the best methods to save money on your energy bills is to stop using incandescent light bulbs and convert them to CFLs or LEDs. Choose ENERGY STAR-qualified bulbs for high-quality products that hold the most energy.

To save electricity, consider using controls such as timers and dimmers in addition to efficient lighting. Timers automatically turn off lights when they are not in use, and dimmers can be used to lower light levels. Make sure that the new products you choose are compatible with the energy-efficient light bulbs you intend to use.

If you have outdoor lighting left on for an extended period, using LEDs or CFLs in these fixtures can save a significant amount of energy. Floodlights made of LEDs and CFLs are available and tested to withstand rain and snow, allowing them to be used in exposed fixtures. 

Look for ENERGY STAR-qualified fixtures designed for outdoor use and include features such as automatic daylight shut-off and motion sensors for the best value. In this article, we will explore the ins and outs of energy efficient light bulbs for your home.

What is an Energy-Efficient Light Bulb?

LED bulbs, compact fluorescent light bulbs, or CFL bulbs are the most energy-efficient light bulbs. LED bulbs employ light-emitting diodes as their light source. 

Instead of mercury, CFLs have an internal phosphor coating that produces light by shining light through the bulb’s filament, thus creating light. 

While LEDs live substantially longer than CFLs (up to 20 years in optimal conditions), their higher cost means that CFLs retain the superior cost-utility ratio for the most part. 

CFLs must be disposed of separately from regular waste due to the presence of mercury and other chemicals. Therefore, LED bulbs may well take over in the future as they become brighter and less expensive.

How important are energy-efficient light bulbs?

Fighting climate change has never been easier or cheaper than it is right now. Bulbs in your kitchen ceiling or chandeliers can either be a significant energy guzzler or a cost-effective strategy to reduce your electricity usage.

In recent years, in the European Union, incandescent bulbs have been phased out and replaced by compact fluorescent light bulbs, or CFLs. According to the Ecodesign Regulatory Committee, this minor adjustment will save citizens nearly 40 TWh each year (TWh=114 million watts).

What are the most energy efficient light bulbs?

CFLs (compact fluorescent bulbs lamps) appear to be the most energy-efficient alternative because they are inexpensive to purchase. On the other hand, LED lights use the least energy and have the longest lifespan, making them the best alternative, despite their higher price.

So we can tell that both the CFL and LED lights are energy-efficient. But the difference is life span and price.

CFL lights

A CFL light, also known as a compact fluorescent light, energy-saving light, or compact fluorescent tube, is a fluorescent lamp meant to replace an incandescent light bulb; specific versions are compatible with incandescent light fixtures. The lamps have a bent or folded tube that fits into the space of an incandescent bulb, as well as a small electronic ballast in the lamp’s base.

Benefits of CFL lights

There are many benefits of CFL lights. Those are-

Energy efficient

In comparison to incandescent bulbs, compact fluorescent lights (CFLs) save four times as much energy and last up to ten times as long. When compared to an incandescent bulb of the same wattage, a 22-watt compact fluorescent bulb produces nearly the same amount of light. In comparison to incandescent bulbs, compact fluorescent lights save 50 to 80 percent of the energy.

High-quality light

Newer CFLs throw out a warm, welcoming glow instead of the “cool white” light of previous fluorescents. The use of rare-earth phosphors achieves excellent color and warmth. There is no flickering or humming with the new electronic ballasted CFLs.

Versatile

There are many places where incandescent lights can be replaced with CFLs. Recessed fixtures, table lamps, track lighting, ceiling fixtures, and porch lights all employ CFLs, which are more energy-efficient. For lights with three-way settings, three-way CFLs are now available as well. Some CFLs can be dimmed to work with lights that have a dimmer switch.

Reduce water and air pollution

By replacing a single incandescent bulb with a CFL over the bulb’s lifetime, a half-ton of CO2 is kept out of the atmosphere. We could retire 90 average-sized power plants if everyone in the US used energy-efficient lighting. CO2, sulfur oxide, and high-level nuclear waste are all reduced when electricity is saved.

Less expensive

Although CFLs are more expensive initially, they save money in the long term because they use one-third of the electricity and the life span is ten times longer than incandescent. Throughout its lifetime, a single 18 watt CFL used in place of a 75-watt incandescent will save around 570 kWh. CFLs correspond to a $45 saving at 8 cents per kWh. For these, you can use energy-efficient light bulbs like CFL lights.

LED lights

Use energy efficient light bulbs

Today’s most energy-efficient and rapidly-developing lighting technology is the light-emitting diode (LED). Quality LED light bulbs last longer, are more durable, and provide light quality comparable to or better than other types of lighting.

ENERGY STAR-certified LEDs consume up to 75% less energy and last up to 25 times longer than traditional incandescent bulbs. LED lighting’s widespread use has the potential to save a lot of energy in the United States.

It is anticipated that LED lighting will be employed in most lighting installations by 2035, and yearly energy savings from LED lighting might reach 569 TWh, equivalent to the annual energy output of more than 92 1,000 MW power plants.

Benefits of LED lights

The benefits of LED lights are so many. Those are-

Long-lasting

LED bulbs can last up to 10 times as long as compact fluorescent lights and up to 40 times as long as traditional incandescent bulbs.

Cool

LEDs create 3.4 btu’s/hour, compared to 85 for incandescent bulbs; therefore, there is no heat build-up. Incandescent bulbs get heated and add to a room’s heat build-up. LEDs help to cut air conditioning expenditures in the home by preventing heat build-up.

Durable

LEDs are safer than incandescent bulbs since they don’t have a filament to burn out. LED bulbs withstand jarring and bumping because they are solid.

More efficient

Only 2-17 watts of power are used by LED light bulbs (1/3rd to 1/30th of that of incandescent or CFL lights). LED bulbs used in indoor lighting conserve energy, stay calm, and save money on replacement costs because they last so long. Small LED flashlight bulbs have a 10 to 15-times longer battery life than incandescent bulbs.

FAQ of the use of energy efficient light bulbs

What is the life span of energy-efficient light bulbs?

LEDs have a 25-year life expectancy under ideal conditions, so you won’t have to buy any more light bulbs for a long time.

How much energy may save by energy-efficient light bulbs?

Low-energy bulbs save about 2000 times their weight in carbon dioxide emissions throughout their lifespan, usually 5-8 years when used in place of regular bulbs. These actions have enormous environmental advantages.

How do energy-efficient light bulbs save energy?

The bulb’s glass tubes are filled with mercury vapor, which is a gas. The mercury vapor then emits ultraviolet light, stimulating the phosphorous coating on the inside of the glass tubes to produce visible light. When you turn on the light, the bulb also has an electronic ballast via which power flows.

Lower-energy lighting tubes may now be produced with any conventional Edison screw or bayonet fitting, allowing them to fit practically any light fixture in the home. Low-energy light bulbs use less energy, which means they contribute less to carbon dioxide levels in the atmosphere.
