A guide to selecting power supplies for LED lighting applications

Thanks to their energy savings, long service life, durability and design flexibility they offer, light emitting diodes (LEDs) are rapidly replacing incandescent and fluorescent technologies in both indoor and outdoor luminaires. But choosing the right LED is only part of the design equation. In order for your solid-state lighting design to realize its full efficiency, durability, and longevity, you'll need to choose a power supply with characteristics which closely match the requirements of your application and the LEDs you're using. This brief tutorial offers some helpful pointers on what you'll need to consider during the selection process.
