With their unique design and performance characteristics—such as directional light emission, compact profile, superior optical control, energy efficiency, breakage resistance, reduced maintenance, and long life—LEDs are well suited to a variety of lighting applications. LED products are most competitive in applications where these performance characteristics outweigh their first-cost disadvantages.
With ongoing research and product development, SSL performance has been increasing steadily. Today, many well-designed SSL products can achieve appropriate light distribution in addition to high efficacy and adequate light output. Market segments where LEDs have made the greatest inroads to date include residential recessed downlights, kitchen undercabinet lighting, portable desk/task lighting, and outdoor area lighting.
