Before the last autumn leaf has fallen, many cities and towns will be sponsoring their annual holiday tree and menorah lightings. Illuminated municipal buildings and shopping centers will lure customers to linger past dark, and at the top of many holiday gift lists will be flat-screen televisions and electronic games and gadgets. From November until January, the season is awash in light.
While candles have marked many holiday traditions for centuries, electric light added a new dimension. In 1882, just three years after Thomas Alva Edison’s invention of the light bulb, an enterprising associate, Edward Johnson, thought of replacing the customary Christmas tree candles with electric light bulbs. But adorning the tree with Johnson's lights was not a simple matter of untangling the string of lights and draping them around the tree — the bulbs needed to be specially made and hand attached to an electric wire. No Saturday afternoon project, achieving a lighting spectacle required a professional to assemble and hang the decorations. Nevertheless, the idea caught on, with President Grover Cleveland inaugurating the first electrified White House Christmas tree in 1895.
Innovations in lighting technology, including parallel lights that remained lit after one bulb in a string burned out, sets of lights that could be connected end-to-end to create longer chains, safety measures to prevent fires, and aesthetic improvements — new shapes, designs and colors — eventually followed, although it would still be many years before the now standard lights came into widespread household use after the First World War.
In keeping with efforts to be energy efficient, the tree at the National Capitol is also now lit with LEDs. Light Emitting Diodes (LEDs) are the newest lights gaining popularity. Because LEDs do not require filaments or glass bulbs, they can produce bright white light, and through the use of refractors, a range of vibrant colors. Moreover, they are being made in a huge variety of shapes and sizes. Even more appealingly, especially in view of the rising economic and environmental costs of energy consumption, the new lights burn longer and more efficiently, and are less subject to damage, all of which make them a desirable consumer alternative to traditional lighting.
