The saying, "you only have one chance to make a first impression" has never been so true than for the CFL. When the highly efficient light bulb was first introduced into the market two decades ago, even the most die-hard energy efficiency experts would agree the technology was probably not ready for prime time. The light output was low and the bulbs took a long time to "warm up".
The DesignLights™ Consortium (DLC), a project managed by NEEP, announced this week the addition of eleven new commercial SSL luminaire categories to its Qualified Products List (QPL). The QPL now lists products in thirty categories. New featured categories include Flood and Spot Lighting, Stairwell and Passageway Lighting, as well as eight retrofit kit categories.
Residential lighting efficiency programs don’t come as cheap as they used to.
