Fluorescent lamps currently constitute 80 percent of lamps installed in the U.S. commercial sector, according to the Department of Energy's latest Lighting Market Characterization report. LED lighting products are receiving a great deal of attention for their potential to replace fluorescent lighting, reduce energy use and improve lighting quality in a variety of indoor commercial applications, including offices, classrooms and retail stores.
The State Partnership for Energy Efficient Demonstrations (SPEED) program drives the market adoption of energy efficient technologies. Managed through the California Institute for Energy and Environment (CIEE), SPEED has conducted more than 100 demonstrations and other technology-transfer projects across the state, showcasing the benefits of best practices and state-of-the-art solutions.
A growing number of LED products are entering the market, adding to the many choices consumers already face. By 2025, 60 percent of residential lighting across the U.S. will likely be LED-based. While nearly all LED lighting choices offer energy savings, not all LED products are created equal, and LEDs may not always be the best type of lamp to use. Professor Michael Siminovitch, director of the California Lighting Technology Center at UC Davis, urges people to consider five things when looking for the right light.
Adaptive exterior lighting products are entering the marketplace at a rapid rate. By coupling features such as occupancy-based lighting controls with efficacious, dimmable sources, these solutions offer 30 – 75% energy savings over traditional systems.
A significant amount of energy can be saved in our homes today with the use of energy-efficient lighting technologies; many of these approaches also improve lighting quality and comport. The following is a list of some of the best technologies you can use today.
Using compact fluorescent lamps (CFLs) to save lighting energy in your home.
This lighting handbook and retrofit guide aims to assist in the process of developing high-performance, energy efficient, quality lighting retrofits for the Forest Service community. During the development of this guide, field evaluations were made to a wide range of Forest Service facilities in an effort to identify the most applicable recommendations.
Pacific Gas and Electric Company (PG&E) business fact sheet looking at current solid-state lighting options for existing luminaries.
This document provides overviews of exterior lighting technologies that would best be integrated into national parks as retrofits or new designs, as well as tips for evaluating light sources, performing a lighting audit, and pairing lamps with lighting controls. The key issues to consider when performing a retrofit or new lighting design are energy, cost, and maintenance savings, and this guide is intended to help make these decisions easier.
