What are the Different Types of Light Bulbs?
There are several types of light bulbs on the market, each with a different price, purpose, and energy-usage. Let’s examine five popular types of bulbs.
Incandescent: A majority of American households use incandescent light bulbs in their home. These bulbs are inexpensive and produce a warm light that is suitable for basic household- or appliance-use. The average incandescent bulb lasts around 1,000 hours.
Halogen: Halogen bulbs are similar to incandescent bulbs, though they are more energy-efficient and last longer. Halogen bulbs produce a bright white light. They become much, much hotter than other types of bulbs and should not be used near combustible materials or touched during or shortly after use.
Fluorescent: These tube-shaped lights are often used as overhead lighting for large areas such as retail stores or home basements. Fluorescent bulbs can last up to 20,000 hours (twenty times longer than an incandescent bulb). They are energy-efficient and produce little heat.
Compact Fluorescent Light Bulb (CFL): CFL bulbs are becoming more and more popular in households across America due to the fact that they use 70% less energy than incandescent bulbs and last ten times longer. Though they cost more than incandescent bulbs, using CFLs can lower your electric bill by up to $35 a year.
Light Emitting Diodes (LED): LEDs are the most energy-efficient bulb on the market; however, they are extremely expensive (currently around $80/bulb). They use half as much energy as CFLs (and 90% less than incandescent), and can last up to 10 years. LEDs produce a bluish light (you’ve probably seen cars with LED headlights on the road at night). Once LEDs become more affordable, they will likely replace less-efficient types of lighting.
