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. 

Daylight may enter a building by way of toplighting (e.g., skylight) or sidelighting (e.g., window) apertures. Good design enables diffuse daylight to serve as a primary source of general illumination while avoiding glare and heat gain. 


General lighting in a living room should fill the space with a subtle warm glow to make it feel inviting and comfortable. The general lighting can be a visual element to personalize the space, such as a chandelier, or blend in with the architecture, such as recessed downlights.

Residential interior lighting is as much art as science. A good residential lighting design is functional and comfortable, blends with the architecture and decor, and helps the owner personalize their home. The result is experienced as work, leisure, living, showcase, castle and sanctuary.


Simply stated, the Sistine Chapel is a really big room with many remarkable paintings, but there are many stories behind the hall and its art.


The light-emitting diode (LED) offers energy savings, lower maintenance requirements and other advantages compared to incandescent sources. However, many LED products perform poorly with existing dimmer controls.

The Dawn Of Commissioning
| under

When commissioning a high-performance building, one element of lighting control is sometimes left out: the daylight harvesting system. It’s assumed such systems will work right out of the box after some simple calibration. Working is one thing, but working optimally is another.
