Who this is for
We generally recommend LED (light-emitting diode) bulbs if you're shopping for whatever light bulbs, regardless of whether you're furnishing a home or replacing a burned-out pantry light. LED bulbs are improve for the environment and your budget. They're significantly more efficient and longer-lasting than CFL, incandescent, or halogen bulbs, so this ultimately saves you money over the life of the bulb. They're also much less decumbent to breaking than the fragile filaments that contain their incandescent counterparts. Many LED bulbs are really fabricated of plastic, which makes them safer to touch and more than durable when you're screwing them in or accidentally knocking them onto the ground, like we're constantly doing—oops. (Don't worry, that's fine, considering they're LED.)
The Section of Energy estimates that LED bulbs employ upwardly to lxxx percent less energy than incandescent bulbs, while also lasting upward to 25 percent longer—leading to serious savings over time. A Bush-era regulation would accept required inefficient incandescents to be phased out, by 2020, in favor of bulbs similar LEDs that reached a certain threshold of energy. Every bit of this writing, this regulation is yet being contested at the federal level, although some states have gone ahead and implemented their own standards—such as California'south Championship twenty—that largely favor the cost and efficiency of LEDs.
Meanwhile, LEDs have entered the mainstream, with more affordable, widely available options in virtually bulb shapes and base types, and manufacturers have fifty-fifty embraced lighting trends like Edison filament bulbs. The best LED bulbs now have loftier colour accurateness and warmer color temperatures that mimic the effects of incandescents. And as of 2020, the average LED bulb costs around $three—still slightly more than than an incandescent, only undoubtedly a better long-term value once you gene in the energy savings and longer lifespan. These products are here to stay, too: According to the National Electrical Manufacturers Association, LED bulbs account for about 70 percent of the shipments in the general service lamp category, every bit of September 2019.
If you're making the switch to LED bulbs, yous'll want to make sure your fixtures and switches are compatible. We tested bulbs using several types of dimmers and found that dimmers designed for LEDs really make a difference in a seedling's performance. With compatible dimmers, our picks dimmed all the mode to zero without plateauing and didn't flicker, buzz, or hum—but with other dimmer styles, the same bulbs didn't work equally well. You tin can check whether your fixtures are compatible if you know the make and model (this web log from 1000bulbs.com has some helpful tips), or get a dimmer switch (we like Lutron'due south in-wall or lamp options).
How we picked
Nosotros fix out to recommend a satisfying and reliable LED version of your basic replacement low-cal seedling. At that place'due south no single perfect light bulb for every lighting state of affairs, so we looked for a line with options for color temperatures and brightness levels to offer flexibility for unlike preferences or applications. We considered these factors when choosing which bulbs to test:
Shape, base, and materials: Light bulbs come in many shapes and sizes, and they accept different types of spiral-in bases. We narrowed this guide's focus to the virtually common type, an A19 shape with an E26 base. This chart shows all of the shape and base styles, ranging from candelabra to trendy world One thousand-shape bulbs. Bulbs can be fabricated from plastic or glass. GE'southward Mathew Sommers said there isn't much applied difference between the two materials for twoscore W or 60 W bulbs, but that plastic bulbs can be better for higher-wattage bulbs. He told us that people (and companies) generally go for whatever is most affordable.
Brightness level options: LED bulbs labeled "60 W–equivalent" are vivid however subtle enough for most scenarios, although many people prefer twoscore W–equivalent bulbs for places similar a sleeping accommodation, where a softer glow helps make the space experience relaxed. Fifty-fifty though nosotros measure LED brightness in lumens, which describe how much light a bulb puts out, people are so used to describing lite seedling brightness using watts that most brands categorize bulbs using a wattage equivalency. The Federal Merchandise Commission (FTC) now requires brands to label all LED bulbs with a lighting facts label, which includes the bulb's brightness in lumens and how much energy it uses in watts. Here's an gauge of how LED wattage equivalents convert to lumens:
40 W = 450 lumens
60 Westward = 800 lumens
75 W = 1,100 lumens
100 W = 1,600 lumens
Dimmability: We chose to examination only dimmable bulbs, because they offering a better ability to customize lighting to arrange your mood, and also to future-proof your purchase. An LED seedling should terminal for years—manufacturers hope at least ten,000 hours of continuous apply per bulb, and the Office of Energy Efficiency and Renewable Energy estimates at least 25,000—then it's wise to choose dimmable bulbs, in case you alter your fixtures, movement, or upgrade a lamp or switch (for example, with a Lutron dimmer). Dimmable bulbs work fine in a non-dimmable fixture; the reverse is not true.
Color temperature choices: Nosotros sought a seedling line with a range of color temperatures. Color temperature is measured in kelvin, and cooler low-cal has a college value, ranging from three,600 to 5,500 Chiliad, while warmer calorie-free ranges from 2,700 to iii,500 K. Virtually brands describe 2,700 Yard temperatures as "soft white," 3,500 K as "bright white," and 5,000 1000 equally "daylight," with some in-betweens. People may prefer libation light for bathrooms, kitchens, workspaces, and garages, and they may prefer warmer lite for bedrooms and sitting areas.
High CRI and R9 values: CRI (Color Rendering Index) measures color accuracy relative to incandescent bulbs, or natural daylight. Although LEDs yet can't friction match incandescent bulbs, which accept a CRI of 100, they've improved significantly in recent years. A CRI of 80 is now standard for LED bulbs. Higher is ameliorate, and great LED bulbs should accurately render colors. Lighting designer Geoff Goral told the states that CRI as a metric has come nether burn for measuring bulbs based on how well they portray pastel colors (instead of more saturated colors). Some bulbs at present likewise list an R9 value, which indicates how well a bulb depicts scarlet tones (making fine art, food, and people look better and less washed-out).
Compatible with enclosed fixtures: Non all LED bulbs will work with enclosed fixtures; nosotros looked for bulbs that do. We limited our search to bulbs meant for indoor use, but some indoor bulbs volition have a weather rating that allows them to exist used outdoors likewise.
Up to electric current regulations: California adopted Championship 20 regulations, effective Jan 1, 2018, which outline strict energy-efficiency requirements for calorie-free bulbs and restrict which bulbs tin be purchased in the state. To shop for compliant bulbs, apply a search filter at Abode Depot or Lowe's.
Low price: If you're furnishing a domicile or even a rental, the cost of light bulbs can quickly add up. We calculated costs per seedling and looked for the most affordable options.
Long warranty: Considering LED bulbs are designed to concluding for thousands of hours and many years, nosotros favored bulbs with longer warranties. LED bulbs don't burn out—every bit they historic period, they fade and lose colour accuracy.
No noise: Adept bulbs shouldn't flicker, buzz, or hum. GE's Sommers explained that poor-quality drivers—the electronic part of the bulb that converts power to your abode—or incompatible dimmers tin cause these furnishings.
With these criteria in mind, we looked for new and notable bulbs in reviews from Digital Trends, Lifewire, and New York Magazine (many of the reviews were outdated or listed unavailable products). We read about what makes the all-time LED bulbs, from sources including Energy Star, Pop Mechanics, 1000Bulbs.com, and Lightology.com. Nosotros scoured the available bulbs on retailers like Amazon, Home Depot, and Lowe's; compared offerings from brands similar Philips, GE, Feit, Cree, AmazonBasics, Sylvania, and Eco Smart; and as well considered bulbs from niche brands like Soraa and Green Creative.
How nosotros tested
We decided to test 40 Westward–equivalent and threescore West–equivalent bulbs, in soft white and daylight color temperatures, both in a real-globe scenario at domicile and in a lab setting, with specialized equipment and help from lighting designer Geoff Goral at the Lighting Pattern Alliance in Long Beach, California.
We by and large wanted to test for colour accuracy. That's because fifty-fifty though a bulb can have a high CRI value, design variations brand each bulb evidence colors differently, and many manufacturers exercise non include information on a seedling's R values, which describe how a bulb shows more saturated colors. We too wanted to exam for dimmability, because LED bulbs often struggle to dim completely and sometimes won't work with older dimmers (resulting in unpleasant flickering, buzzing, or humming).
Nosotros weren't as concerned with measuring other specs. The LED light bulb industry is closely regulated by the IES, or Illuminating Technology Order, and the Department of Free energy. The FTC now requires that manufacturers label all bulbs with a lighting facts sheet that outlines a seedling's lifespan, brightness, and color temperature.
For the flat tests, nosotros ready a colorful, fruit-and-flower-filled still life scene on a kitchen table. And then, nosotros screwed each seedling into an overhead fixture that was plugged into a Lutron dimmer, noting whether bulbs buzzed or flickered, how well they dimmed, and how well they showed colors. We conducted all tests in the late afternoon and with other lights turned off for consistency. We took photos of the scene nether the light of each seedling using a transmission white balance to compare colors and brightness levels. Our photo editor adjusted the exposures and white balances for consistency among photos with 60 Westward and 40 W bulbs, and nosotros compared the photos.
Although these tests were interesting, they were inconclusive and subjective, with observations nosotros couldn't quantify. And then nosotros asked the Lighting Design Alliance's Geoff Goral for help. Wirecutter editor Tim Barribeau brought 21 bulbs to Long Embankment, California, where Goral measured and compared each bulb for color accurateness, dimmability, and relative effulgence levels. Goral used an illuminance meter, to measure how much light emanated from a bulb onto a surface, and a spectrometer, to read the spectrum of light from each bulb, to run into how much calorie-free was in each wavelength and measure colour values R1-xv. To test for compatibility and to summate how dim the bulbs could get, Goral tested each bulb in a dimmer box with four styles of dimmers—ones designed for LED, incandescent (TRIAC), MLV, and ELV, all of which Lutron explains in item.
With Goral helping us interpret the test results, we compared the bulbs' performance and came abroad with conclusive results.
Our picks: Cree lx W Equivalent Soft White and Daylight A19 Dimmable Exceptional Light Quality LED Calorie-free Bulbs
Our pick
Cree's 60 W Equivalent A19 Dimmable Exceptional Lite Quality LED Calorie-free Bulbs in both Soft White and Daylight versions performed meliorate than any other bulbs in our tests. These bulbs accurately show colors, and have high CRI (Coloring Rendering Alphabetize) values, and then your bananas volition wait yellow and your apples reddish. Unlike other bulbs, the Cree LED bulbs are able to dim all the way to zero on an LED dimmer. This line of bulbs likewise has the longest warranty of whatsoever brand we found.
Nosotros wanted to recommend a line of nifty bulbs from one brand to make outfitting a whole house with lights less complicated, and Cree offers standard LED bulbs in 40 Westward–, 60 W–, and 75 W–equivalent brightness levels with soft white, bright white, and daylight colour temperature options. All of these bulbs are Title 20–compliant and bachelor for buy in California, while equivalent bulbs from GE and others are not. Subsequently observing how well Cree'due south xl Westward and 60 W bulbs performed in our tests, nosotros feel confident recommending other LED bulbs from this brand as well.
The 40 W and 60 Due west Cree bulbs accept a CRI rating of xc, one of the highest out of all the bulbs we tested—and far closer than LEDs in the past have come to mimicking that incandescent-quality glow. We found that the Cree bulbs had the all-time colour allegiance—colors equally they appear in real life. The 60 West Cree bulbs had the highest R values in our tests, so they still show saturated colors well (the forty West bulbs were also amid the best for color accuracy).
The yet-life fruit scene set up in the apartment looked like we had dialed up the contrast with an Instagram filter without opting for a preset—just slightly enhanced. Colors nether the Cree Daylight bulb looked crisp and clean without being likewise blue-tinged or blown out: The tiny buds on broccoli florets were nicely defined, and white stripes stood out against the fuschia skin on a Graffiti eggplant. Nether the Cree Soft White seedling, apples and lemons looked like slightly golden versions of themselves.
In our dimmer tests, the Cree bulbs were some of the but ones that could dim all the way to zero without plateauing, flickering, buzzing, or humming. By contrast, almost all of the other bulbs we tested had problems with various dimmers. Although the Cree bulbs worked with incandescent dimmers, they performed the best on LED-compatible (or CL) dimmers. The Cree'southward superior dimming capabilities were noticeable even in our flat tests; they dimmed lower than whatsoever other bulb using simply a Lutron dimmer.
The Cree bulbs are an affordable selection for furnishing a home, and prices volition likely subtract over time. At the time of writing, prices range from about $3.50 to $4 per bulb. Cree besides offers a x-twelvemonth warranty—the longest nosotros've seen for bulbs—in case bulbs fade earlier their advertised lifespan.
Flaws but not dealbreakers
We previously recommended Cree bulbs, and we received some reader feedback about bulbs that burned out after just 1 or ii years. Because of Cree'south long warranty and its available client service (compared with, say, that of AmazonBasics), we are comfortable recommending this brand, despite some problems. The experts we spoke with all commented on how LED engineering science has progressed, so nosotros're hopeful that the most contempo iteration of Cree bulbs will agree up better. We're using these bulbs in our own homes and volition go on to assess their operation over time.
Cree sells bulbs in 2-packs; we wish information technology offered greater quantities at lower prices.
Runners-up: Feit Electric Daylight and Soft White lx W Equivalent Dimmable A19 Light Bulbs
Runner-up
If Cree LED bulbs are unavailable or you prefer slightly warmer colors, we recommend the Feit Electrical Soft White and Feit Electric Daylight 60 Due west Equivalent Dimmable A19 Lite Bulbs. These bulbs are rated at a 90+ CRI, compared with the Cree's standard 90 score; it'southward a subtle deviation, just if you lot place the bulbs side by side, you'll discover the Feit bulbs are merely a chip more radiant. All the same, this too means that as the Feit bulbs dim lower, they appear brighter and slightly more yellowish than the Cree bulbs, which might not exist ideal for every setting. These lights did plateau (as in, they stopped their continuous rate of dimming) as they dimmed virtually zippo percentage. But otherwise, they worked almost equally smoothly and well as the Cree bulbs. If you're fine with (or even prefer) that merchandise-off, the Feit bulbs are a proficient selection when the Cree aren't bachelor. They're easy to find online or in stores, and typically cost anywhere between $2.l and $3 apiece, which is about boilerplate for LED bulbs. They're also fully compliant with California's Championship xx, and come with a five-year warranty; that'southward only half the warranty on the Cree bulbs just otherwise fairly standard.
What to look forrard to
After a yr of existence trapped inside our homes, however, it seems these color-irresolute bulbs are catching on—and might accept some real value afterwards all. "People are looking for ways to go the most out of their spaces to transition from work/school to relaxing all using the aforementioned spaces, especially with Covid," Dana Knight, Senior Managing director of Global Marketing at Feit told united states over email. So we decided to take another look at these kinds of bulbs, every bit well as several other new bulbs that offer smart-similar functionality without any bodily connectivity.
If you're interested in Smart LED lighting that can be controlled through your voice assistant, we accept more details in a separate guide. If there are whatever other new LED bulbs that nosotros've missed—either from brands yous've seen in your local stores, or models that boast new features or technologies—please permit us know in the comments section.
The contest
In 2021, nosotros tested and dismissed several LED bulbs with non-smart, not-standard features such as color-switching abilities or built-in speakers.
Despite what its name implies, the Feit 60-Watt Equivalent A19 Air Purifier Bulb OM60 doesn't actually "purify" the air. Instead, it functions more similar an ionizer. Some people claim in that location are benefits to negative ion improvidence; the EPA says it's "relatively ineffective in removing large particles," and can actually produce some slight ill effects if not used in moderation. Either manner: there's no meaningful air purification going on here, although the bulb itself is otherwise fine.
We previously recommended Philips's bones, dimmable bulbs—the 60 W Equivalent A19 LED with Warm Glow and the 60 W Equivalent A19 Dimmable Free energy Saving LED Low-cal Bulb Daylight, likewise as the equivalent 40 Westward Soft White and 40 W Daylight options—as our runner-upwards picks. Nosotros withal retrieve they're pretty good overall, simply they're non as readily available in stores as the Cree or Feit bulbs. The Soft White bulbs also come with a "Warm Glow" characteristic, which increases the bulb'southward color temperature as information technology dims. Some people might prefer this aesthetic, just it also causes the bulb to lose color fidelity as it dims, bathing your decorations or the contents of your dinner plate with an exaggerated bister glow.
GE makes several bulbs with proprietary engineering science that modify color representation: the Reveal, the Relax, and the Refresh. These bulbs were fine, but they didn't stand out in our tests, and they're a picayune more expensive and accept shorter warranties. The GE Reveal has a colored picture show over the bulb to create more colour contrast. It fabricated colors announced more than saturated in our tests, which nosotros liked. But information technology flickered when paired with incandescent or MLV dimmers, and it didn't dim very depression. This bulb likewise doesn't run into Championship 20 requirements and isn't bachelor in California. The GE Refresh bulbs use proprietary applied science to make colors either warmer or bolder, to create more contrast. They too didn't dim well in our tests.
The Philips SceneSwitch claims to create a dimming effect without a dimmer, by changing between three color temperatures. Just in tests information technology didn't always switch accurately, and when nosotros placed information technology on a dimmer, information technology buzzed audibly (and was the only bulb to exercise so.) Reviews too mentioned that if you use multiple SceneSwitch bulbs, they sometimes won't sync upward, resulting in different bulbs with unlike color temperatures.
