The lower the kelvin, the warmer a bulb appears. Take a look at the image below and you'll get an idea of how different lighting can affect an office setting. Choosing between these types of light bulbs is a personal decision. In a household setting, you may like one color temperature and stick with that throughout the home; or you may choose different color temperatures to set a different feel for each room.
For instance, you may want warm bulbs in dining rooms and bedrooms, white bulbs in kitchens, and cool bulbs in utility areas like laundry rooms and workshops. Again, it's a matter of personal taste. When you shop for light bulbs at Lighting Supply , you'll find a refinement option on our site to sort bulbs according to their color temperature to help you more easily find the bulbs you need.

And you probably wouldn't want daylight over the dining room table or soft white in the kitchen. Color temperature is one of the reasons smart bulbs are such a convenience. Instead of buying bulbs specific to a room or activity, you can change the color of the lights on the fly.
For instance, if you prefer a daylight color to read by at night but don't want to sacrifice the cozy warm light when you're not reading, you can put a smart bulb in a bedside lamp and change the color to daylight when you're reading and during the day and soft or warm white at night. If you haven't taken the plunge yet, here are five reasons to consider smart bulbs. Also, check out CNET's light bulb buying guide. Be respectful, keep it civil and stay on topic.

Understanding light bulb ratings Not all light bulbs are the same. Delivered Tuesdays and Thursdays. What's the Right Wattage? Wattage doesn't tell you how bright a light is—it only tells you how much energy the lightbulb is using. For example, if you're replacing a watt incandescent bulb, you'll want to use a to watt CFL.
In essence, a CFL produces more light with less energy. But the wattage doesn't necessarily impact lumens, which measures the amount of light emitted. This can be helpful when comparing a watt incandescent bulb producing lumens with a watt compact fluorescent producing lumens—they're nearly identical in how much light they cast, but one uses much less energy.
Understanding Lightbulb Color Lightbulbs come in a variety of shades, from bright white, to blueish, to yellowish. Put simply, the color temperature of light is rated in degrees Kelvin. The lower the Kelvin number between K to K , the more yellow the light. Higher Kelvin numbers, say K to K, emit a bluer light.
For a white light, look for bulbs marked K to K. In January , all lightbulb boxes will be required to tell consumers where the bulb falls on the color spectrum.
Selecting bulb color will become much easier. Make sure that you don't choose a lightbulb with a higher wattage than your lamp allows. It can be tricky with the lower wattages to know what is the right wattage in CFLs or halogens. Energy Star has very helpful charts to help you figure out what bulb is best for you. If you're choosing a lightbulb for outdoors, make sure that it's in a fixture that protects it from getting wet.
