Color Temperature

Color temperature is a way of measuring how closely the light emitted by a light bulb resembles actual daylight and is measured in degrees Kelvin (K). Bulbs that give off a warmer, more yellowish shade of light register at a much lower K than bulbs that give off a cooler, bright white or slightly bluish hue, which is much closer to the look of daylight.

Watts & Lumens

Understanding light bulb terminology is important when selecting the right bulbs for your needs. Two of the most common lighting terms you’ll encounter are watts and lumens. See below for a brief definition of these terms and how they can help you select the best lighting options.


  • Measures the amount of energy that a light bulb uses.
  • The lower the wattage, the less energy it needs to operate.
  • Since bulbs can have the same brightness while using different amounts of energy, watts are a poor way of measuring brightness.


  • Standard way of measuring light bulb brightness.
  • Higher number of lumens signify a brighter bulb.

Understanding Light Bulb Sizes

When you’re shopping for a new light bulb, it’s important to understand sizing to be sure it will fit in your fixture. Each bulb has a code that indicates its shape and diameter at the widest point measured in eighths of an inch.

For example, an A19 code indicates that it's a classic A-series light bulb with a diameter of 19 eighths of an inch (2.38 inches or 60.33mm). To get the correct width measurement, be sure to measure it at the widest point, which varies with the type of bulb you're looking for.

How to Read the Labels

Light bulb labels will provide you with all of the information you need to help you find the bulb best suited to your desired application.


Measurement of the brightness (light output) of the light bulb. The higher the lumens, the brighter the light bulb. You will want to look for lumens now vs. watts when shopping for brightness of light bulbs.

Estimated Yearly Energy Cost

Based on three hours of use per day at the average U.S. electricity price of 11 cents per kilowatt hour. This cost may vary based on local electricity rates and how long your lights are on.


How long your light bulb is expected to last based on being turned on for three hours per day.

Light Appearance

The light bulb’s color temperature and is measured on a Kelvin (k) scale ranging from 2700k - 6500k. Light bulbs with a color temperature in the warm range (2900 - 3000k) will have a softer yellowish light. Light bulbs that are labeled cool white and have 4100k temperature have whiter light whereas light bulbs with 5000k to 650k are meant to mimic natural daylight.

Energy Used

Measurement in wattage of the light bulb. The 200 EISA Legislation requires that new light bulbs use 25% less energy than traditional incandescent light bulbs. Many of the new energy saving LED, CFL and halogen light bulbs consume less energy.

Energy Star

The ENERGY STAR logo on the label means that the U.S. government has recognized this product as providing significant energy savings without sacrificing performance. It also highlights that while the product might cost more up-front, customers will recoup this additional investment through long-term energy savings.
