Even though human eyes behave like miniature cameras, the film or digital sensors that cameras use to measure the level of light are not as forgiving as our eyes when it comes to perceiving natural colors in various lighting environments. Understanding the composition of white color light has numerous applications in photography, film-making and light design consultation.
Intelligent solutions for parking lot lighting
Parking garages and lots constitute an industry that generates at least $25 billion a year in gross revenue in the U.S. And with their many needs beyond just providing parking spaces for cars and other vehicles, like accessibility, safety and the ability to blend into surrounding environments, they present dynamic spaces where intelligent commercial lighting design can make a huge impact in a number of ways.
LED lighting is the next big investment
Energy-efficient lighting solutions, specifically light-emitting diodes (LEDs), is the next major market to experience significant growth, according to a recent report by CleanTechnia. The LED industry will open new markets, encourage new business models and increase product capabilities.
A look at the history, present and future of the lighting market
The number of light bulb and other lighting products has expanded exponentially over the years. Earlier generations only had to choose between different types of traditional incandescent bulbs, and those choices rarely had anything to do with better technology or efficiency, but were instead essentially based on which manufacturer they liked better. But over the past 25 years, lighting has become one of the most complex markets in the world.
Colorado Springs installs LED streetlights
Colorado Springs, Colo., is moving forward with its second installation of LED streetlights. The city previously replaced 370 high-pressure sodium and mercury vapor cobra head streetlights with solid-state fixtures and saved 50 percent on energy costs. The next installation will include 95 LEDs in Colorado Springs’ downtown area.
Energy Department announces investments in energy-efficient lighting
The U.S. Department of Energy announced five manufacturing research and development projects it plans to invest $10 million in to support energy-efficient lighting products. According to the release, the projects not only focus on reducing manufacturing costs but on the continued improvement of quality and performance for light-emitting diodes (LEDs).
How light interacts with vision
When light enters the eye, it is focused by the lens onto the back of the eye where there are millions of specialized cells that transmit the light information into a series of biochemical reactions that result in a chemical signal being sent to the brain. The brain then organizes that data into an image – the picture that is seen.
Energy performance contracts guarantee savings
Energy performance contracts are a means for commercial property owners to make their commercial electric lighting, HVAC and other systems more sustainable. . An overhaul to a building’s systems with high energy consumption rates yields instant economic savings, which are then free to be spent on the replacements.
Metal halide is alive and well
When it comes to commercial lighting solutions, metal halide lamps have many applications because of their versatility in large-scale outdoor and indoor lighting. In our gyms, hotels, and supermarkets, we have seen these lamps. Compared to mercury lamps, MH lamps were a more efficient choice, as they produce 30-57 more lumens per watt.
Colorado energy efficiency group announces available funding
Nonprofit group Energy Outreach Colorado (EOC) announced it is accepting applications for its Nonprofit Energy Efficiency Program (NEEP). The nonprofit raises funds for statewide energy assistance and energy efficiency programs provides qualifying nonprofits with free energy efficiency upgrades to facilities serving low-income clients, the group said in a statement.
