Watch as Steve demonstrates some of the applications for Optek's LED Lighting Strips, such as Under the Counter Lighting, Decorative Lighting, Background Lighting, and a few Not-so-Typical applications. The possibilities are endless!

All of the focus on thermal management of light emitting diodes raises the question: is it always worth the cost? For LEDs, every penny must be applied efficiently. The benefits of lower junction temperature are well known, but there is a tipping point between investing additional product cost in thermal management and getting a return on that investment. Good thermal management starts with clear product and application definition.

The purpose of this application bulletin is to answer design questions about high-power visible light emitting diodes (LEDs).
