LEDs
LEDs can be used in virtually any fixture—indoors or out—and are the most energy-efficient and long-lasting bulb out there. Although the initial cost is higher, its average 25-year lifespan and low energy use makes it the least expensive option over a course of 10 years. LED bulbs don’t need time to warm up, don’t produce excess heat, and are available in a variety of hues, sizes and styles.
To make sure you are receiving the best quality LED, look for the ENERGY STAR® label.
CFL – Compact Fluorescent Lighting
You may recognize CFLs for their spiral style and warm-up time, but they do come in other shapes and sizes. Some CFLs may need a few minutes to warm up, but once they get going they will burn bright, producing 90% less heat while delivering more light per watt. However, CFLs do not withstand constant on-and-off switching and actually last longer in areas that need to be lit for at least 15 minutes. This makes CFLs ideal for living rooms, kitchens and dining rooms, but not the best choice for a bathrooms or closets where you may experience frequent “burn-outs.”
CFLs are about 70% more efficient than traditional incandescents and can last up to 10 times longer.
Halogens
Halogens have a less expensive initial price tag, but cost more to run and do not last as long as CFLs or LEDs. They are slightly more energy-efficient than traditional incandescents, but reach a much higher temperature. Because of the heat factor, they are best used in lighting fixtures that are farther from reach—like recessed, ambient and flood lighting.
