When you strip out the benefits from things that do not require networking, network lighting systems have a payback period of over 20 years and are, in our view, economically unjustified.
On the “rebound effect” in energy efficient lighting or why LEDs aren't like other energy efficiency
Buyer beware: the rise and rise of integrated LED products
Integrated LED products are relatively new to the marketplace, appear to be the future, and may or may not be a good idea. We’ll evaluate three major lighting applications that are seeing an influx of integrated options—track lighting, downlights, and troffers—for what they cost, what the products mean for users, and where we recommend using LED lamps versus integrated LED fixtures.
