Energy-efficient lightbulbs can be found at several retailers – and for a good reason. They are less expensive, last longer, and offer brighter light than most traditional bulbs.

But what makes an energy-efficient lightbulb the best? Let’s break down what to look for when shopping for energy-efficient options and why replacing the bulbs in your home is a great way to help keep your energy costs down.

Key takeaways

  • The main types of energy-efficient lightbulbs are LED, CFL, and Halogen bulbs, but LEDs are the most common because they are the most efficient and the cheapest.

  • Our top 5 are based on their performance, longevity, and cost.

  • Energy-efficient lightbulbs help reduce your electricity bill and can last for years at a time.

What types of energy-efficient bulbs are there?

There are three varieties of energy-efficient bulbs: light emitting diode (LED), compact fluorescent lightbulbs (CFL), and Halogen lightbulbs. The three main energy-efficient bulbs differ because of the way that they generate and emit light.

LED: LED lightbulbs emit light when a current flows through them. The current interacts with a semiconducting material, as in electricity-generating. In this case, the material is the diode. The diode then emits light.

CFL: True to their name, CFL lightbulbs have a fluorescent coating within the bulb. Mercury and argon fumes are also contained within the bulb and transform electric currents into UV light. The presence of mercury in these bulbs makes them a challenge to dispose of safely, so they are not our top choice.

Halogen: Halogen bulbs work by using halogen gas to generate electricity and through this process, the gas is recycled, making the bulbs last longer. These bulbs do last the longest but they put off more heat, which is not ideal in a home setting.

What's the most common energy-efficient lightbulb?

The most common type of energy-efficient lightbulb is LED, because it is the most efficient and affordable, and they last the longest with about a 10-year lifespan. LED bulbs are our top choice due to their low cost and great output. But, CFLs are a good second choice.

What to look for when choosing an energy-saving lightbulb

A few things you should check for when deciding on a lightbulb are the bulb's lumens, the color of the bulb, whether it has the ability to dim, and the space you need the bulb for.

For instance, a dining room might require mood lighting where a dimming bulb is necessary while a bright white might make more sense in a bathroom. It’s important to ensure the light fixture can support the wattage of the bulb you are buying for it.

As for lumens, those are essentially a measure of light output per bulb. Watts, on the other hand, measures energy use. Generally, 800 lumens is a good number to look for but standard 100 W bulbs emit 1,600 lumens.

The available types of bulb color temperatures are soft white, warm white, and bright white. They all are perfect for various rooms.

The top 5 energy-efficient lightbulbs

Looking for the Energy Star label is an easy way to find a trusted brand. Energy Star is an Environmental Protection Agency-backed label to help consumers choose energy-efficient appliances. Once you determine what you need a lightbulb for, it's easy to choose one from our top picks.

Why choose an energy-efficient bulb?

Energy-efficient bulbs are the way to go. They save money and last longer than traditional incandescent lightbulbs. Energy efficient bulbs, especially those with the Energy Star label, are made to not waste the same amount of energy that traditional bulbs do.

Since there is less wasted energy, less electricity is used, which means lower bills for you. It also means that these bulbs are more environmentally friendly, with less carbon dioxide emitted to power the bulb. But if you have solar panels, energy-efficient bulbs ensure that the power from your solar energy goes further.

It’s not just lightbulbs that can lead you to an energy-saving, less pollution-producing home. Be even more environmentally friendly by adding solar panels to your house. You can switch to energy efficient appliances and get a home energy audit to lower your electricity bill. But the biggest savings come from installing solar panels, which can eliminate your energy bills entirely!
