The term volumetric means that which relates to measuring volume. The term volumetric lighting apparently originated in the computer-generated graphic arts with an early application to three-dimensional (3D) gaming and computer-generated imagery in movies.
Essentially, volumetric lighting refers to the illusion created when a lighting technique suggests a certain perspective, orientation or effect that increases, enhances or magnifies the sense of volume in a given space, context or application. For example, a shape of light, such as a cone, is directed toward a particular area, making it appear as if it’s a transparent container of a specified volume. This technique can foster — especially through the use of steam, fog or smoke — the perception that the shape of light inhabits an actual three-dimensional space. In reality, volumetric lighting draws one’s attention toward an area, creating this 3D perception.
In residential and commercial lighting design, volumetric lighting is often synonymous with task lighting, such as light fixtures designed with optics that have a luminous, distinguishable beam spread which can be purposefully directed to light art, a table, produce in a market, etc.
For example, observe the diagram pI turned here of a grocery store’s produce department; it shows the use of volumetric lighting and spot lighting with track lighting to emphasize a display of fruits and vegetables.
This bright, intensified lighting approach uses more electricity. Accordingly, opting for volumetric lighting which uses Light-Emitting Diode (LED) reduces electricity costs. Another advantage of LED volumetric lighting is that it emits 80 percent less heat, which, in turn, benefits the shelf-life of heat- sensitive items, such as produce or cheese. In any case, volumetric lighting may be a constructive choice for you.

Art can use light to convey an emotion, mood or thought, transcending language. Artists have always used light to emphasize certain aspects of their works of art. How light bathes a basket of fruit, for example, or shines on a pearl earring, can accentuate an art work’s attributes. The contrast of darkness with lightness can be alluring. In modern art, only the medium has changed.
At Alcon Lighting’s LA headquarters, co-founder David Hakimi adopted a 12 year-old dog named Nano and decided to bring him into the office every day. Let’s just say it garnered some attention. It quickly became clear that Nano, who’s now 14 years old, relishes a long nap. Nano likes to hop and curl up in an easy chair, resting his head on the arm, drifting into slumber. In fact, David says this is Nano’s favorite activity.
As the United States of America celebrates Independence on the Fourth of July, it’s worth remembering lighting’s role in the American Revolution. Revere’s light signal was a backup plan designed to warn patriots in Charlestown, a borough across the river from Boston, in case Revere was arrested by the British occupying Boston and thus unable to initiate the ride.
“98% of what gets built today is sh**. There’s no sense of design nor respect for humanity or anything. They’re bad buildings and that’s it.” – Frank Gehry. Fun fact: One of Frank Gehry’s most famous works as an architect is his own private Santa Monica residence.
The Continental Congress passed an act establishing an official flag for the new American republic on June 14, 1777. President Truman declared June 14 as Flag Day August 3, 1949. Anyone considering displaying America’s flag for Flag Day today or on Independence Day on July 4th might want to give some thought to proper illumination.
