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 demand for LED lighting and controls increases, the lighting world is becoming more complex, which raises demand for expertise to produce good lighting solutions. Unlike other professions, lighting designers do not require state licensure.

A suitable application for tunable white lighting is in classrooms. The system used in the room shown above offers four settings. In “calm” mode, the lights are set at a standard intensity level and warm shade of white light, oriented toward calming an excited class.

The color appearance of light sources can have a major impact on how people perceive spaces. In high-end retail, hospitality and similar applications, color temperature choice is a critical design decision.

Color tuning is often used for purely aesthetic purposes—creating lighting “scenes” or particular atmospheres. However, research suggests it could find a new home in healthcare facilities.

Light-emitting diode tube lights, or TLEDs, are gaining recognition of their own in residential and commercial buildings.

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.
