Glow lights have created a revolution in the lighting scene and they can be used in a variety of indoor and outdoor situations. From domestic use and electronic manufacturing to aesthetic appeal, these lights are being used in many gadgets that require a source of illumination. Glow lights are available in a variety of colors and forms and provide several desirable effects.
Glow Light Products
Three major types of glow lights are available: glow sticks, glow-in-the-dark lights and “Light Emitting Diode” or LED lights. Glow sticks are plastic cylinders with glass vials that produce light when the glass vial is broken. A chemiluminescent reaction between two chemicals in the stick causes the glowing light.
Glow-in-the-dark lights are phosphorescent products that must first be charged to create light. When exposed to light, the phosphors are charged with energy that stimulates their electrons to produce light.
LEDs provide light through a process called electroluminescence. LED lights are powered either by electricity or batteries, can be reused and can last for a very long time.
Effects of Glow Sticks
Glow sticks are commonly used today as toys, decorations and even necklaces. They do not provide enough illumination for full visibility, but these lights do have aesthetic effects. They are often worn by individuals at rave parties to accentuate body movement and create ambiance.
Although quite popular, the chemicals in glow sticks have a low level of toxicity and can cause irritation. When a glow stick breaks, the liquid inside can cause a burning sensation to the skin and eyes. If this liquid is swallowed, it can cause a burning sensation in the throat. The small glass particles contained in the plastic stick can also cause serious damage to the throat and digestive tract if ingested.
Glow-in-the-dark glow lights do not provide sufficient illumination to be used in traditional lighting and their main purpose is aesthetic in nature. They are labeled as “phosphorescent” products, meaning they absorb light and release that energy in the dark. Most glow-in-the-dark products do not contain harmful chemicals since their glow comes from natural sources such as the sun. These phosphorescent products are often placed in gardens, parks and other locations where the sun can charge them during the day. At night, the lights give off a calming and relaxing glow that adds beauty to the location.
Among the three types of glow lights, LEDs offer the brightest illumination, as they rely on electricity and batteries for power. For this reason, LED lights are not only used for aesthetic purposes but also as a form of subtle lighting in gardens, houses and even vehicles. LED glow lights are also used in home d cor, batteries, night sports gear, military night vision equipment, clothing and electronics such as computer keyboards, vehicle decorations and headlights. LED lights can produce a brighter glow if they are designed to handle higher wattage.
