LED or light emitting diode technology can be found all around us — in the glowing indicator lights on electronic devices, in traffic lights and exit signs.

LED shows promise for someday becoming the energy-efficient choice for general lighting in our homes. But the technology is still developing and the cost, in many cases, is still prohibitively high. Currently, compact fluorescent lights remain your best bet for savings in most cases. But there are a few LED options you can consider now.

• More energy efficient than incandescents and some CFLs
• Long-lasting — up to 50,000 hours
• Very rugged
• Good for directional lighting
• No mercury
• No infrared or ultraviolet light
• Cool to the touch
• Range of colors

• More expensive than incandescent bulbs or CFLs
• Not widely available
• Light output is limited to lower light level applications
• Because LEDs cast light in one direction at a narrow angle, they are not yet practical or cost effective for general illumination
• Sensitive to heat, which can hurt performance and lifespan

• Holiday lighting. Strings of LED lights are your best bet for holiday lighting. They use just a fraction of the energy required by standard C7 holiday lights, and they’re also much more energy-efficient than even mini-lights. They are very rugged and last for years. Stores are stocking more LED holiday lighting options every year.
• Limited residential applications. Look for LED strip lights to use under cabinets and counters. They work well as step lights, nightlights and task lights. LED replacements for recessed can lights are also becoming a viable residential application.
