How to Save Money When Buying Indoor and Outdoor Lighting

Light emitting diodes (LEDs) are a type of solid-state lighting -- semiconductors that convert electricity into light. Although once known mainly for indicator and traffic lights, LEDs in white light, general illumination applications are today's most energy-efficient and rapidly-developing lighting technology. LEDs use up to 90% less energy and last up to 25 times longer than traditional incandescent bulbs. 

LED technology is available in many lighting product types including replacements for 40W, 60W, 75W, and 100W traditional incandescent bulbs, reflector bulbs used in recessed fixtures, and track lights, task lighting, undercabinet lighting, and outdoor area lights. LEDs come in a variety of colors, and some bulbs can be tuned to different colors or different hues of white light.  Some are dimmable or offer convenient features such as daylight and motion sensors. LEDs work well indoors and outdoors because of their durability and performance in cold environments. Look for LED products such as pathway lights, step lights, and porch lights for outdoor use. You can also find solar-powered LED outdoor lighting. 

The cost of LED light bulbs has decreased dramatically since they entered the market and prices are expected to come down further as more products become available. While LEDs are more expensive than traditional incandescent bulbs, they still save money because they last a long time and have very low energy use. 

When designing outdoor lighting, consider the purpose of the lighting along with basic methods for achieving energy efficiency.

Outdoor lighting for homes generally serves one or more of three purposes:

• Aesthetics: Illuminate the exterior of the house and landscape
• Security: Illuminate the grounds near the house or driveway
• Utility: Illuminate the porch and driveway to help people navigate safely to and from the house.

Here are some basic methods for achieving energy-efficient outdoor lighting:

• Security and utility lighting does not necessarily need to be bright in every instance to be effective.
• Consider LED flood lights with combined photosensors and motion sensors in the place of other security lighting options.
• Make sure outdoor light fixtures have reflectors, deflectors, or covers to make more efficient use of the light source and help reduce light pollution.
• Use timers and other controls to turn decorative lighting on and off.
• Use outdoor solar lighting where applicable.
