Energy-efficient light bulbs are a low-cost, high-reward upgrade that can lead to saving both energy and money. Unlike other energy-efficiency upgrades, replacing incandescent bulbs with high-efficiency ones requires no infrastructure or electrical tweaks (they use the same sockets), and is a breeze to undergo. The results include impressive cost savings ($225 in savings annually for the average home) and meaningful reductions in your home’s environmental footprint.

Energy efficiency is the most readily available and untapped fuel source. It’s abundantly available, easy to extract and cost-effective. While an incandescent light bulb has a cheaper price tag than more efficient options, you’ll end up paying way more in energy usage, plus the costs to continuously replace them. Energy-efficient lighting is also an important strategy to combating climate change: Just upgrading the planet’s light sources to 100% LED could save the planet nearly $5 trillion over equipment lifetime and prevent nearly 18 gigatons of CO2 emissions between 2020 and 2050.

5 Best Energy-Efficient Light Bulbs of 2022


Creating a nice ambiance is tough with most LEDs. They get a bad rap for being woefully non-dimmable, as the majority of LEDs on the market burn at a steady wattage. And for those advertised as “dimmable,” many folks report choppy adjustments and irritating flickering. The GE Relax Dimmable LEDs are a refreshing exception. Smooth dimming and consistent warm light expand your lighting options to suit any occasion, offering greater color contrast and boldness versus standard LED bulbs.

These are ideal for creating cozy, dimmable lighting perfect for bedrooms, foyers, family rooms and dining. A warm 2700K hue does away with the sterile harsh lighting typical of many LEDs. These general-purpose bulbs work on most dimmers and last 13 years based on three hours of use per day.

Customer Rating: 4.6 out of 5 stars with over 1,800 Amazon ratings

Standout Review: “These GE Relax bulbs are the only ones that don’t buzz or hum when on lower settings. Dimming is very smooth with no flickers. They also have the added benefit of being able to dim very low compared to other bulbs I have tried.” — MAC via Amazon

Why Buy: These awesome LED bulbs take on double-duty as general-purpose bulbs with consistent dimming. They’re perfect for any warm lighting needs, capable of delivering enough lumens to light up a room and dimming down to candle-like luminance.



Philips’ Indoor CFL Light Bulbs offer 100-watt equivalent lighting from a 23-watt bulb. These CFL bulbs are made with recycled glass and recycled packaging materials for an even greater reduced environmental impact.

Why Buy: This CFL option is over twice as bright as most LED bulbs and offers more natural lighting sometimes unachievable by LEDs. If a CFL bulb is a must for you, this bulb’s brightness, recycled content and natural daylight hue make it a compelling option. Just make sure you dispose of it properly, as CFL contents can be harmful to human health and the environment.

How to Choose the Best Energy-Efficient Bulbs

So, which is the best energy-efficient light bulb for your home? Here are some criteria to keep in mind when making a purchase:

There are three main types of energy-efficient bulbs commonly available:

Choosing the shape and size of your energy-efficient light bulbs is part aesthetics, part function. Aesthetics aside, a bulb’s shape affects light dispersion, filament types and more. Bulb shapes are represented by letters on the box:

The numbers on the side of bulb boxes refer to the bulb’s widest point, an important factor when considering if a bulb will fit where it needs to go.

A bulb’s hue and light color are called temperature, measured in Kelvins. Warm light (2700K-3000K) produces a yellowish glow for a relaxing and intimate feel. Cool light (3500K-4100K) yields a clean, efficient and welcoming ambiance. Daylight (5000K-6500K) creates a bluish-white light comparable to the sun at noon on a cloudless day.

In the old days, bulb brightness was measured in watts. Watts still matter, but not so much in determining the brightness of an energy-saving light bulb. Modern LEDs use incandescent wattage as a point of reference, displaying watt equivalents. The brightness of LED bulbs is also listed in lumens. The more lumens, the greater the light output. When looking for brightness, think lumens, not watts. Here’s a general rule of thumb from the Department of Energy:

Most energy-efficient light bulb purchases will be the standard A-type with a conventional screw-in base, and they’re nearly all designed to be compatible with your home’s existing fixtures. If you have smart-home devices, make sure to purchase smart lighting. For 12-volt appliances, you’ll need to make sure your new bulb is compatible with the fixture’s voltage rating, base and spatial constraints.

While LEDs and CFLs are significantly more expensive than incandescent bulbs, the savings of energy-efficient bulbs will pay for themselves relatively quickly. However, not all energy-efficient light bulbs are priced equally. Smart bulbs and specialty Edison-style bulbs are more expensive than standard LEDs.
