What fitting do you need?
This is basic, yet you truly would prefer not to foul it up.
Albeit there are truly many light fittings in presence, your home likely just has a few. I've got two in my roof fittings, a few all the more in table lights. In the picture underneath there are some regular ones for the UK and US.
Bring your old bulb with you
Sounds goofy, but it's a sure way to know that the LED or CFL fits your fixture since some energy-saving bulbs are bigger or heavier than the incandescents they replace. Replace bulbs that are on the most and use the most energy. Typically they're the main lighting in the kitchen, dining area, and family room. Bring our Ratings too. They'll come in handy as you stare at shelves lined with hundreds of bulbs and can't find sales help that's helpful.
CFL vs. LED
Compact Fluorescent (CFL) and Light Emitting Diode (LED) bulbs are the most energy-efficient light bulb options. They have lower wattage than incandescent bulbs, but emit the same light output. This allows them to produce the same amount of light, but use less energy. View the chart for key differences.
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 60-watt incandescent bulb, you'll want to use a 13- to 18-watt CFL. In essence, a CFL produces more light with less energy.

In any case, the wattage doesn't essentially affect lumens, which measures the measure of light transmitted. This can be useful when looking at a 100-watt radiant knob creating 1690 lumens with a 23-watt reduced fluorescent delivering 1500 lumens—they're about indistinguishable in the amount of light they cast, yet one uses considerably less vitalit
Match Fixture Base
• Screw-in bases include miniature candelabra, candelabra, intermediate and medium
• Pin bases typically have two pins, such as those used for many halogen lights
Choose Color Temperature
• Soft light for indoor applications and small areas• Bright light for outdoor lighting and indoor task lighting
Choose a bulb with a long lifespan
Longevity is an important factor when considering how to buy a light bulb. Compact fluorescent bulbs are both long lasting and energy efficient if a long lifespan is the most important quality you are searching for as you determine which light bulb to buy. Similarly, you may want to look at fluorescent light bulbs as you shop for light bulbs. They are long lasting and are popular in large spaces such as schools and office complexes. Halogen bulbs have a long lifespan and are energy efficient.Other light bulb buying considerations
- You may want to consider several other important factors before buying energy-efficient light bulbs – including their color rendering index (CRI), their fixture ratings, and their working temperatures.
- Use outdoor-rated bulbs for outdoor locations.
- Color rendering index (CRI) shows how accurately a bulb can illuminate colors. Select bulbs with a CRI of at least 80 to ensure accurate color rendering. Note that not all manufacturers identify CRI on their packaging.
- Do not use non-dimmer-rated CFL or LED bulbs in dimmers.
- Buy dimmer-rated LED and CFL bulbs for fixtures with dimmer switches or that have night-light or security timer settings.
