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.

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.
Contrary to their domesticated canine counterparts, cats don’t need constant attention. They generally lie low by lounging in the sun or trying to cram their bodies into small undersized cardboard boxes. In fact, most of the time, their humans are in the way. As proof, here’s a collection of architectural photographs where the photographers were inconveniently in the way.
Some of the world’s greatest artists were inspired by light — the way it hit a basket of fruit, or shone off a pearl earring. It’s the combination of dark and light that inherently fascinates us, and in today’s modern era, the only thing that’s changed is the medium. Light art explores this juxtaposition quite literally, through light, but in the form of sculpture, manipulation, colors, and shadows.
