Dimmable CFLs work differently than incandescent bulbs. Not all CFLs are dimmable so check the packaging to make sure it is. Three-way bulbs typically come in Soft White color temperature.įixtures or lamps with dimmer switches require the use of dimmable CFLs. Installing three-way CFLs may require extra effort since they can be slightly larger than their matching incandescents, but they still use one-third as much electricity. Check the packaging to make sure that the bulb is intended for this use. Timers, photocells, and motion sensors may not be compatible with CFLs so if you have one of these controls on your outdoor lights check with the manufacturer of the control and the CFL packaging for compatibility.įixtures or lamps with three-way switches require the use of a three-way CFL. Because of this, they’re usually much larger then the reflectors designed for use inside. Some indoor reflector bulbs can be used with a dimmer - the packaging will tell you.įor use outside, reflector bulbs are sealed to withstand the rain and snow. Indoor reflector bulbs are much smaller then those that are designed for outdoor use. Reflector bulbs are perfect for providing directional light - think of recessed ceiling lights in kitchens or ceiling fans. The sleek shape also allows you to use them in tight fitting light fixtures where a covered globe won’t fit. These products are ideal for use in decorative fixtures where you can see the light bulb. Basically straight versions of the spiral bulbs, tubed bulbs work well in lamps that have slender covers such as wall sconces. Some of the first ENERGY STAR qualified light bulbs were tube shaped. But be patient - ENERGY STAR qualified light bulbs generate just as much light as traditional bulbs, while using less energy. Like other covered CFLs, globe bulbs need a little time to “warm up” and reach full brightness. A globe bulb is basically a spiral bulb with a decorative cover. Globe-shaped bulbs are ideal for use where you can see the bulbs, like bathroom vanity bars and ceiling pendants. Check the packaging for compatibility with dimmers and three-way fixtures.
You can use A-shaped bulbs wherever you used to use traditional incandescent bulbs, such as clip-on lamp shades. These products are great for consumers who don’t like the look of the spiral bulbs but still want efficient lighting. Spirals also come in a variety of colors like soft white, natural light, or daylight.Ī-shaped bulbs combine the efficiency of the spiral bulbs, with the look and feel of the traditional incandescents. There are spirals for dimmers and three-way switches (just check the packaging).
Many traditional bulbs around your home (from 60w to 150w) can be replaced with spirals. Spiral CFLs create the same amount of light as traditional incandescent bulbs, but use less energy. If these spiral-shaped light bulbs look familiar it’s because they’re the most popular type of Compact Fluorescent Lamp (CFL).
