The Continental Congress passed an act establishing an official flag for the new American republic on June 14, 1777, stating “…that the flag of the United States be thirteen stripes, alternate red and white; that the union be thirteen stars, white in a blue field, representing a new constellation.” President Truman declared June 14 as Flag Day on August 3, 1949.
Historians believe the first American flag was designed by New Jersey Congressman Francis Hopkinson and sewn by Philadelphia seamstress Betsy Ross, though this is a matter of some dispute.
In any case, 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.
Generally, when darkness makes it necessary, it’s best to illuminate the American flag with wide angle flood bulbs. Depending on the distance, LED wide angle flood lights which direct light in a wider beam spread, account for the flag’s movement in the wind.
Whether hanging a U.S. flag on a front porch bracket, which is common for residential display, or hoisting or displaying the flag on a commercial or residential property flagstaff, the flag ought to be properly lighted after sundown. The alternative is withdrawing the flag from display.
According to the U.S. Flag code, as the law passed by Congress in 1942 came to be known, America’s flag should be displayed at dawn and lowered or removed at dusk. Those choosing to display the flag at night should consider using two or more lighting fixtures, depending on the flag’s size and the height of the flagstaff or pole.
Two to three fixtures should be installed around three feet from the flag pole and directed toward the top of the pole. Lighting fixtures producing 500 to 750 lumens are considered ideal. This calculation is based upon flag poles ranging in height from 10 to 25 feet.
Most American flags measure up to 4 x 6 feet. Displaying larger U.S. flags, such as those that measure 6 x 10 feet, may mean using three fixtures. Note that when America’s flag is displayed either horizontally or vertically, such as on a wall, the Union (the blue field) is best displayed to the observer’s left.

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.
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.
Tesla was a prolific inventor and patent holder. One of his primary contributions was alternating current—a development that—dare I say—powers the world we live in today. Critical for lighting. Critical for facebooking. Indispensable for all things (alternating current, not Facebook).
