Which Light Bulbs Are Right For You?

With so many types of light bulbs available, it can be overwhelming to select the right ones. Read this guide to determine what you need for your fixture, space, and budget.

Factors to Think About

*Lumens (brightness)
*Wattage (energy used)
*Appearance (warm vs. cool)
*Bulb lifespan
*Estimated yearly cost
*Contains mercury?
 
When shopping for light bulbs, take a look at the Lighting Facts label on the packaging in order to compare different bulbs. The label looks similar to a Nutrition Facts label:

Lumens
Lumens represent the amount of light emitted from a lightbulb. The more lumens, the brighter the light. When purchasing light bulbs, start by comparing how bright of a bulb you want before factoring in other characteristics, as lumens are the same across the board. The number of lumens needed to light a room depends on the size, color of the walls, and how much light you prefer.
 
Watts
Watts are the amount of energy a light bulb uses. The higher the watts, the higher the electric bill. (CFLs and LEDs have a lower wattage than incandescent.) When purchasing bulbs, follow instructions provided by the lighting fixture about the maximum wattage. A bulb with too high of a wattage can create a fire hazard due to the production of excess heat. It can also damage the light fixture.
 
Today, light bulb packaging shows the number of lumens. If you’re used to looking at wattage to figure out how much light you need in a room, check out this helpful chart below.

Types of Light Bulbs

Incandescent
Incandescent bulbs are the traditional bulb type, but today, standard 60- and 40-watt bulbs are no longer produced or sold. This has been the case since 2007, when Congress passed the Energy Independence and Security Act, which requires incandescent light bulbs to be 25 percent more efficient.
 
Halogen Incandescent
Halogen bulbs are perhaps the closest alternative to incandescent bulbs, but with a longer lifespan. While more energy-efficient than incandescent, they are still not as efficient as CFL or LED bulbs. These inexpensive bulbs produce a crisp, bright light, and do not fade with age. They operate at high temperatures, which can cause burns if touched, but they do not contain any mercury. Halogen bulbs are commonly used as task lighting — think spotlight or flood light bulbs.
 
CFLs
Compact Fluorescent bulbs (CFLs) emit a similar light output in the same color range as incandescent bulbs, but consume significantly less energy. CFL bulbs can be used anywhere a typical incandescent bulb would go, including both indoors and outdoors. These bulbs may take a few minutes to reach their maximum output.
*CFL bulbs do contain a small amount of mercury, and care should be taken to prevent breakage, as well as to dispose properly.
 
Fluorescent
Fluorescent lights need a controlling ballast to operate, but new ballasts eliminate the buzz and flickering often associated with fluorescent lights. In addition, fluorescent lights are now available in a wider variety of colors and sizes. Fluorescent lights are energy-efficient, but like CFL bulbs, require a warm-up time and proper disposal. They also produce a small amount of ultraviolet (UV) radiation, which some people may be sensitive to.
 
LEDs
Light Emitting Diode bulbs (LEDs) are just as energy-efficient as CFLs, but with a longer lifespan. In general, LED bulbs are pricier than other options, but are becoming more affordable as they grow in popularity. LEDs are cool to the touch and do not contribute to indoor heat buildup. They come in a variety of whites and colors, and are also shock-resistant.
 
Smart LEDs
These “smart bulbs” have all the characteristics of traditional LED bulbs, but connect to your home Wi-Fi to be controlled by a smartphone or other smart home device. These bulbs will set you back a bit more than your average LED bulbs, but allow you to change the color, set an on/off timer, and more.
