Understand the true cost of LED choices in SSL systems

The solid-state lighting (SSL) industry has focused on LED component cost as the key to lower upfront costs for LED-based lighting and broader deployment. And indeed lower LED prices are important for broader SSL adoption. Still, there can be hidden system-level costs and reliability issues tied to the selection of LED components, which SSL developers must understand to deliver products that perform well at install and throughout an extended life. Lengthy LM-80 testing of components is paramount to robust lighting products. Let's examine some background on LED manufacturing and trends, discuss SSL application requirements, and then consider how the hidden cost of LED components can impact the success of a general-lighting product.
