Strobe lights became popular in the 1970s, when they were commonly used in nightclubs. Strobe lights now have many other purposes, and are used for many things besides creating a party atmosphere. They are seen in various fields, including emergency, industrial and scientific. Although they are high-voltage lights, they are generally low wattage, and you probably see them on a daily basis. Does this Spark an idea?
Strobe lights are commonly used in nightclubs and other nighttime settings, such as sports, music festivals and theatrical events. Many commercial businesses use strobe lights to advertise special offers. The strobe light is placed in such a way as to accent the product or service they wish to advertise. They can be used indoors in ice, hockey and roller rinks. You can time the strobe light to flash at a specific speed per second, or set it to flash based on audio beats.
Experiment with strobe lights and photography. Strobe lights can alter light, shadows and contrast when pointed in the direction of the subject. Using strobe lights of different colors will create more vibrant outcomes. Try taking shadow portraits by placing the strobe light behind a figure and projecting the shadow on a blank wall, therefore allowing you to take photos of the shadow, or negative image.
Strobe lights have a purpose at special events, such as haunted houses during Halloween. Place the lights to accent certain features of the set. The effects of strobe lights projected indoors and close-up will cause the speed of a moving object to appear slower, then faster. One second, the person is moving toward you, and with the next flash he is directly in front of you.
Dangers of Strobe Lights and Epilepsy
Strobe lights can trigger epileptic attacks in photosensitive epileptics. The British Health and Safety Executive recommends not using strobe lights for more than 30 seconds at one time in public and commercial places. It is also suggested that five flashes or less per second will reduce the effect on an epileptic to five percent. These standards and guidelines do not apply to emergency vehicles and other emergency light uses.
