Lighting

 

 

Lighting and controls is a huge, constantly changing, dynamic market. The ELECTRICAL CONTRACTOR lighting editorial listed below keeps current on technological innovations from LEDs, controls, and design to innovations in efficiency by traditional lighting formats. 

As local government and business owners look for ways to improve efficiency and reduce greenhouse-gas emissions, outdoor lighting has become one of the most practical ways for them to reach their goals.


LED streetlights have the potential to reduce energy consumption by about 50 percent compared to traditional high-pressure sodium lights. According to a U.S. Department of Energy (DOE) survey of governments and utilities, 62 percent of respondents reported using LED sources in their streetlighting.

In May 2016, the DesignLights Consortium (DLC) released Networked Lighting Controls System Specification V1.01. By the end of June, the DLC published a Qualified Products List (QPL) for networked controls. This may have a profound impact on demand for networked controls in existing buildings.

The Environmental Protection Agency (EPA) has christened the fourth Tuesday of every October as national Energy Star Day. This year, the agency marked the holiday by issuing a call-to-action to change out inefficient light bulbs with Energy Star certified bulbs.

Paying Attention: Lighting Trends

It’s a little like the chicken and the egg when you ask who sets lighting trends. Is it the manufacturer or the lighting designer? In truth, it’s likely both. Keeping up on how each pushes the needle can help electrical contractors maintain or enhance value with customers.

Dimming Demand: Lighting Control in Demand Response

The average commercial building electric bill often features a consumption and demand component. The consumption component reflects the amount of electric energy (kilowatt-hours) used, and the demand component shows the maximum demand (kilowatts) during the billing period.

Hard Numbers: Responsive Lighting

Estimating lighting control energy savings is challenging, as actual savings depend on application characteristics, such as occupant behavior, building design, site orientation, daylight apertures, interior reflectances, device settings and level of commissioning.

The Right Light: Color Tuning

While light makes sight, lighting shapes perception, particularly in regard to color in the things we see. This is because visible white light is made of colors. For us to see an object as a certain color, that color must be present in both the light and the object.
