Literature Summary of Lifetime Testing of Light Emitting Diodes and LED Products

A summary of the literature on lifetime definitions for LEDs and LED products, including a look at failure mechanisms, accelerated life tests and test methods for estimating lifetime, and provides some recommendations. There is currently no agreement as to which test method can best estimate the lifetime of LED lighting products and the report thus addresses a key issue for regulators and industry interested in deployment of LED technologies


Harnessing IoT for Energy Benefits

This report examines the landscape of residential IoT products and the functions within those products that can be leveraged to yield energy benefits. These functions include monitoring via on- board sensors and internal or external data feeds, and controls that can reside within or external to the product. We examine the extent to which products possess these functions today, the energy benefits products can achieve with those functions, and the appropriateness of adding additional functions to achieve additional energy benefits.
