LEDs are better at placing light in a single direction than incandescent or fluorescent bulbs. Because of their directional output, they have unique design features that can be exploited by clever designs. LED strip lights can be installed under counters, in hallways, and in staircases; concentrated arrays can be used for room lighting. Waterproof, outdoor fixtures are also available. Some manufacturers consider applications such as gardens, walkways, and decorative fixtures outside garage doors to be the most cost-efficient.

LED lights are more rugged and damage-resistant than compact fluorescents and incandescent bulbs. LED lights don't flicker. They are very heat sensitive; excessive heat or inappropriate applications dramatically reduce both light output and lifetime. Uses include:

• Task and reading lamps
• Linear strip lighting (under kitchen cabinets)
• Recessed lighting/ceiling cans
• Porch/outdoor/landscaping lighting
• Art lighting
  
• Night lights
  
• Stair and walkway lighting
  
• Pendants and overhead
  
• Retrofit bulbs for lamps
