LEDs are available in more styles than ever before, from standard bulbs to decorative fixtures and smart options. With so many choices, picking the right bulb can feel overwhelming. Fortunately, understanding a few key details can make choosing the right LED much easier.
Watts measure the amount of energy a bulb uses, while lumens tell you how bright a bulb will be.
LEDs provide the same brightness as incandescent bulbs while using much less energy. This means you'll be looking for a bulb with fewer watts to provide the same light level you are used to.
When shopping for an LED, look for lumens rather than watts. If you're replacing an older bulb, use this chart as a guide.
For example, if you're replacing a traditional 60-watt bulb, look for an LED that provides about 800 lumens.
LEDs also come in different color temperatures, which affect whether the light appears warm or cool. Color temperature is measured in Kelvin (K). Lower numbers produce warmer, more yellow-toned light, while higher numbers produce cooler, bluer light.
Warm white light around 2700-3000K is popular for living rooms and bedrooms. Cooler light (around 3500-4100K) can work well in kitchens and workspaces. Meanwhile, 5000K and above provides a crisp, daylight-like appearance.

LEDs are available in many shapes and styles, so always check what type of bulb your fixture requires before purchasing one. The standard A19 bulb works with many common lamps and fixtures, while other fixtures may require globe, candle, reflector, or specialty bulbs.
If you're using a dimmer, make sure the LED is labeled as dimmable and that your switch is compatible, since some older dimmer switches may not work properly with LEDs. The bulb should also be appropriate for where you plan to use it, such as indoors or outdoors.
Before buying a bulb, look at the Lighting Facts label on the packaging. It provides useful information, including the bulb's brightness, estimated yearly energy cost, expected life, light appearance, and energy use. Using the label makes it easier to compare your options.
Choosing the right LED doesn't have to be complicated. By checking brightness, color temperature, bulb style, and the Lighting Facts Label, you can find lighting that works well for your space while keeping energy use in check.
Start by replacing the bulbs you use most often and taking advantage of natural light whenever possible. You can also pair LEDs with controls such as motion sensors, daylight sensors, or dimmers to save even more. Some bulbs and fixtures even have built-in sensors.
