Several years ago, the Federal Trade Commission mandated that light bulb packaging includes bulb specifications. We’ll discuss those light bulb terms, but first let’s discuss the different types of light bulbs.
Types of Light Bulbs
There are several types of light bulbs used in residences:
- Incandescent bulbs are the traditional bulbs we all know. Light is generated when electricity is passed through a filament that heats up, thus producing light. While you may still have incandescent lights in your home, many have gone the way of the eight-track tape, floppy disc, etc. because they are very inefficient. Good luck finding them at the hardware store or online.
- Halogen bulbs, while more energy efficient, still are not as efficient as LED lights (see below).
- Fluorescent lamps, those long tubes that can be a pain to insert, use fluorescence to product light. As these lamps use mercury, they are also not used as much.
- LED lights are the latest thing. They have a semiconductor light source that is long-lasting and much more energy efficient. They cost more initially, but their energy efficiency and long life make them a much more economical and energy-efficient alternative.
Reading the Label
The label provides useful information when you purchase LED lights. Here are the light bulb terms you’ll see:
Lumens
Lumens measure the brightness of the bulb. The more lumens the brighter the bulb.
LED light lumens can be compared to incandescent bulb wattage: Here is the conversion table:
- 1,600 lumens / 100 watts
- 1,125 lumens / 75 watts
- 900 lumens / 60 watts
- 600 lumens / 40 watts
- 375 lumens / 25 watts
Light Appearance
Light appearance is determined by the color temperature of the bulb. Color temperature is measured in Kelvin (K) and ranges from warm to cool. Bulb temperatures range from less than 2,000K to 5,000K.
- Less than 2,000K emits a dim glow similar to candlelight. Use it to create ambience.
- 2,000K-3,000K will emit a warm, yellowish light that can also create an intimate and relaxing feel. This type of light is good for bedrooms, living rooms, and dining rooms, as well as outdoor locations.
- 3,100K-4,500K emits a cool light that is brighter than incandescent cool lights. These are appropriate for task lighting in kitchens, offices, vanities, workspaces, etc.
- 4,600K-6,500K emits a bright, blue-white light similar to daylight. It is ideal for display areas and work environments.
- 6,500K and higher emits a bright blue hue and is frequently used for task lighting in commercial locations.
Life
Life is the expected life of the bulb. LEDs can last 20 years or more, compared to one-year at most for incandescent bulbs. LEDs do not burn out but will fade over time. LEDs are considered useful until the light has diminished by 30%.
ENERGY STAR
The ENERGY STAR designation means the bulb uses 20% to 30% less energy than federal standards require. Better news is it also means you may be able to get rebates from your utility company for these bulbs.
Energy Cost
The LED packaging will show you estimated annual energy cost, based on specific usage.
