Types of Bulbs

It may seem like you have a lot more choices today when it comes to light bulbs—and you do. Here are the most common types of lighting technology used in homes.


CFL - Compact Fluorescent Lamp

CFLs are an energy-efficient lighting choice that use about 1/3 the amount of energy as incandescent bulbs.

They may cost a little more up front, but more than make up for it by saving around five times the purchase price over their lifetime. CFLs come in a wide range of styles to fit your every need.

LED - Light Emitting Diode

LEDs use less energy than even CFLs, but it’s their long lifespan—up to 25 years—that really sets them apart.

LEDs can also have a higher sticker price, but more than make up for it in everyday energy savings and longevity. Like CFLs, LEDs also come in a range of shapes, sizes and styles.



This is the original light bulb technology and the style you typically think of when you hear the words “light bulb.” The major drawback is that 90 percent of the energy consumed is wasted as heat, making them an incredibly inefficient option. In fact, incandescent light bulbs are so inefficient that federal lighting standards have already phased out 40w, 60w, 75w, and 100w bulbs from the marketplace. While there may still be some leftover stock on shelves, this type of bulb is no longer manufactured. Look for energy-efficient CFLs or LEDs instead.


Halogen bulbs are a form of incandescent lighting that is slightly more efficient than your standard bulb. In this case, more efficient doesn’t mean a whole lot, as CFLs are nearly three times more efficient than halogen bulbs.
