LED vs. CFL vs. Halogen
Now that most incandescent lightbulbs are pretty much a thing of the past, consumers now must choose between LED (light-emitting diode), CFL (compact fluorescent), and halogen bulbs to light their homes. But which is the best option? It all depends on your needs. We’ll take you through the various kinds of lighting, and the benefits that each offers.
LEDs vs. Incandescent Bulbs
Traditional incandescent bulbs measured their brightness in watts; if you wanted a brighter bulb, you bought one with a higher wattage. However, with the advent of LEDs and other types of lighting, that yardstick has become meaningless, and as a result, a bulb's brightness is now listed as lumens, which is a more accurate measurement of how bright it is, rather than how much energy it consumes. Below is a conversion table which shows how much energy, in watts, an incandescent bulb and an LED typically require to produce the same amount of light.

|Incandescent Bulb (Watts)||Lumens||LED Bulb (Watts)|
CFL and Halogen bulbs
Other replacement lightbulb choices consume more power than LED bulbs and have shorter rated-lifespans, but cost much less upfront.
A 60-watt–equivalent CFL bulb from Philips, for example, consumes 13 watts and has a rated lifetime of 12,000 hours (or about 11 years) when lit for three hours a day, but retails for only $1.50-$2.00.
While technically a form of incandescent lighting, halogen bulbs are more efficient than traditional bulbs, and so the ban does not affect them. Many companies now sell “eco-Incandescent” bulbs which look like traditional lightbulbs, but use halogen elements. But they are still no match for LEDs. A 60-watt–equivalent halogen bulb from Philips consumes 43 watts and has a rated lifetime of 0.9 years. However, it retails for just $1.00-$1.25.
Other Lightbulb Alternatives
EISA will also stop the manufacturing of candle-and globe-shaped 60-watt incandescent bulbs (the types used in chandeliers and bathroom vanity light fixtures). However, the law doesn't affect 40-watt versions of those bulbs, nor three-way (50 to 100 to 150-watt) incandescent A19 bulbs. So, those will continue to be an option for you, as well, in fixtures that will accommodate them.

LED Lightbulb Options
Traditional bulbs for table and floor lamps are known by their lighting industry style name "A19,"while floodlight bulbs made for track lights and in-ceiling fixtures are dubbed "BR30." Your best long-term alternative to either style is extremely energy-efficient LED technology.
The LED equivalent of a 60-watt A19 bulb consumes only between 9 and 12 watts, and provides about the same light output, measured in lumens. A 40-watt equivalent LED bulb consumes only 6 to 8.5 watts. And a 65-watt BR30 (floodlight) replacement LED bulb consumes only 10 to 13 watts.
Moreover, an LED bulb's lifespan is practically infinite. Manufacturers typically estimate a bulb's lifespan based on three hours of use per day. By that measurement, an LED bulb will be as good as new for at least a decade, manufacturers say. Under the same conditions, an old-fashioned lightbulb may work for only about a year before burning out.
For example, GE's equivalent LED bulb has a rated lifetime of 15,000 hours or 13.7 years. Philips' equivalent LED bulb has a rated lifetime of 10,000 hours or 9.13 years.
LED bulbs will continue to light up even after their rated lifetimes expire; however, brightness may drop or the color cast of the light may change.
GE, Philips, Sylvania, Cree and other brands (including IKEA) all offer LED bulbs that output the most popular "soft white" light, at retailers including Home Depot, Target and Walmart. In addition, GE ‘s Reveal lineup of color-enhancing lightbulbs (a coating filters out yellow tones to enhance colors lit by the bulb) with LED replacements equivalent to 40-watt and 60-watt A19 bulbs and to a 65-watt BR30 bulb.
Initially, LED bulbs cost a lot more than old-fashioned incandescent bulbs, but now have dropped in price. For example, a 4-pack of Philips 60-watt-equivalent soft white LED bulbs costs about $10 at Home Depot, a cost of $2.50 per bulb.
When they first came out, LED bulbs emitted a bluish light that many found harsh compared to the “warmer” light cast by traditional bulbs. However, LED makers now offer LED bulbs that emit different color temperatures, measured in Kelvin. Here are a few that you’ll most likely find at a home improvement store:
2700K: These bulbs will be labeled “soft white,” and will cast a gentle warm glow that’s good for the bedroom, as well as table and floor lamps.
3000K: “Bright White” bulbs have a more neutral glow, being neither warm nor cool.
5000K: Lights that are 5000K and higher will typically have a “daylight” label, and edge towards the bluer part of the spectrum. However, they will best approximate actual sunlight.
Smart LED Bulbs
A new subset of LED bulbs are so-called “Smart Bulbs,” in that they can be controlled by your smartphone, and often have other features built in, such as the ability to work with a wide range of smart home devices. However, these also cost more than other LEDs.
Smart bulbs fall into two categories: Those that require a hub to connect to your home Wi-Fi network, and those that don't. The advantage for the former is that they tend to be smaller and less expensive than Wi-Fi-enabled bulbs. However, setup is a little longer, and involves connecting a hub or bridge to your Wi-Fi router, and then linking the bulbs to the hub. Some companies, such as Philips, include a bridge with their bulbs, but many can also be linked to third-party smart home hubs, such as the Samsung SmartThings, Wink, and the Amazon Echo Plus.
Companies whose bulbs require a bridge or hub to connect to your Wi-Fi network (which includes Philips, Sengled, and IKEA) often sell starter kits, which include several bulbs plus the bridge.
Philips' most basic kit is the Hue White Starter kit, which includes two bulbs and the hub. While you can't change the color of these bulbs, they are dimmable. Also, the Philips Hue app is the most comprehensive of all those we've tested, and works with a lot of smart home systems, including Alexa, Google Home, and more.
The Philips Hue White and Color Ambiance kit ($199), which comes with the Bridge and four bulbs, which can change color. Philips also has an app, Philips Hue Sync, which lets users synchronize their smart bulbs with multimedia content on their Mac or Windows PC. For example, you can set your lights to flash and change color in time with music, video, and movies being played on your computer.
If all you're looking for is basic white dimmable bulbs, Sengled offers a more affordable option than Philips. A starter kit with two bulbs and a hub cost $39.99, while a kit with four bulbs costs $54.99. However, Sengled's app is less robust than Phillips'.
Sengled has also released a set of color bulbs, each capable of producing 16 million colors; the Sengled Element Color Plus Lighting Kit includes three bulbs and a bridge for $129. Additional bulbs cost $35 each.
The C by GE C-Life Starter Kit is awkwardly named, but includes two bulbs, as well as a hub for connecting them to your home network and Alexa. While these lights are dimmable, you can't adjust their color temperature; for that, you'll need the C by GE C-Sleep bulbs, which cost about $48 for a two-pack.
Even IKEA is getting into the smart lighting game. Its Tradfri line includes several bulb types, including an A26 (essentially an A19), GU10, as well as a remote control, dimming switch, and a motion sensor. These bulbs also require a gateway hub to connect to your smartphone via Wi-Fi. However, we found that these bulbs were a pain to set up, they don't work with other smart home systems, and you can't control them when you're not at home.
Bulbs with built-in Wi-Fi can connect directly to your router, so there's no need to install a bridge first. However, on a per-bulb basis, Wi-Fi bulbs tend to be more expensive and larger than their counterparts.
TP-Link's bulbs have Wi-Fi built in, so you don't need to connect them first to a bridge, as you do with Philips Hue and Sengled Element bulbs. The basic dimmable bulb costs $19.99 each, but you can get them in a 3-pack for $54.99, which lowers the price per unit. TP-Link also sells a tunable white A19 bulb for $26.99, a multicolor A19 bulb for $35.99, a dimmable white BR30 bulb for $29.99, and a multicolor BR30 bulb for $49.99. And they all work with Alexa and IFTTT.
Lifx has an assortment of smart bulbs, of which the Mini White is the smallest and least expensive. It's dimmable, has an output of 800 lumens, and uses about 9 watts of electricity. Other Lifx bulbs include the multicolor Mini ($39), and the Mini Day & Dusk ($29), whose white output is tunable, from a cool, bluish light to a warm, reddish white.
All of Lifx's bulbs work with Alexa, Google Home, and HomeKit. Lifx also sells a multicolor dimmable bulb for $44.99.
Cree’s Connected LED bulbs will work with WeMo, as well as the Amazon Echo, Samsung’s SmartThings, Wink, and others. You can buy them individually, or in packs of six.
Sylvania is launching a Bluetooth-enabled bulb that will work with Apple's HomeKit smart home platform. This A19 bulb can connect to an iPhone, iPad, or Apple TV (4th generation or later), and then be controlled from the Apple Home app, or through Siri voice commands. The bulb, which has adjustable white color temperature from 1200K to 6500K, will ship in September; by then, Sylvania expects that it will work with additional smart home systems.
Bulbs with Extra Features
In addition to providing light, there are a number of smart bulbs that have added features, such as speakers, Wi-Fi extenders, and infrared lights.
BeON's bulbs have a built-in microphone that listens for the doorbell and fire alarms, and will turn the lights on automatically. The module also contains a small battery, so it can turn the lights on for about 4 hours even if your house loses power. A single bulb costs $50, and a pack of three bulbs and smart modules costs $129.
The Lifx+ line of smart lights, which includes A19 and BR30 bulbs, are Wi-Fi-connected multicolor, dimmable bulbs that provide utility even when they're off. That's because they have infrared lights built in, which provides additional illumination for security cameras to see in the dark.
The Sengled Pulse is a pair of LED lights with a JBL Bluetooth speaker in each; they can be paired together for stereo sound. The Sengled Boost ($45) has a built-in 2.4GHz 802.11n Wi-Fi repeater; the Sengled Snap ($149) is an outdoor light with a security camera, so you can monitor who’s coming and going. However, early Amazon reviews with the Snap have been less than positive.
The Stack Downlight Starter Kit has sensors that cause the lights to turn on when someone enters the room, and will automatically adjust the color temperature based on the time of day. They also will brighten and dim depending on the amount of sunlight coming into a room. In addition to the BR30 downlight kit, Stack's Classic Starter Kit has A19 bulbs.
Because LEDs are so small, they can be used in a variety of shapes and installations, from long strips of light to even more exotic designs.
The Philips Hue LightStrip is 80 inches long, and can display millions of colors. You can trim the strip to fit your needs, and an adhesive backing makes it easy to stick to a wall or other surface. Like other Philips Hue lights, the LightStrip works with Alexa, HomeKit, and Google Assistant, as well as Nest and Samsung SmartThings. However, you'll need to already own the Hue bridge to get these lights to work.
The Nanoleaf Aurora will make a statement. Part lighting, part wall art, you can change the colors of each triangular panel to one of 16.7 million colors. You can set timers for the lights to turn on and change colors, and it works with Apple HomeKit, so you can pair it with other smart home devices. The starter kit comes with 10 panels; you can add up to 30. A rhythm module, sold separately, will also pulse the lights in time to music it hears.
