There are a variety of artificial lights, including LEDs, incandescents and gaseous discharge. Artificial light is that which people have created in order to provide illumination for buildings.Know More
LEDs (light emitting diodes) can provide different colored light. These vary from shades like white to ones like blue, red, and green. RGB lights combine different color sources into one. These are still a newer light source than other types of artificial lights.
One of the most common light sources, incandescent bulbs provide illumination through a filament within the bulb. Halogen lamps are also a type of incandescent that use halogen gas. Fluorescents also burn gas to function.
Gaseous discharge lights work similarly to halogen lights. They utilize gas to provide illumination. High-intensity discharge lights or HIDs are also a type of gaseous discharge light that use gases such as metal halide, high pressure sodium, and mercury vapor to provide illumination.Learn more about Lighting
LEDs (light emitting diodes) are brighter than incandescent or halogen bulbs of the same wattage, but LED bulbs are not available in high wattages. Some of the brightest LED flood lamps use 11-12 watts and emit light comparable to a 50-watt incandescent bulb.Full Answer >
An incandescent light bulb uses electricity to heat up a tungsten wire encased in a glass shell until it glows. Because this light source also gives off heat, it is often used in incubators and lava lamps and to speed the drying process.Full Answer >
The Home Depot lists more than 15 different types of light bulb bases, including medium, candelabra, medium skirted, bipin and twistline. Other base types include intermediate, mogul, widepin and candelabra bayonet. Each bulb base requires its own receptor on a light fixture.Full Answer >
A light bulb is non-ohmic because it does not obey Ohm’s law. According to Ohm's law, "The ratio of potential difference to the current flowing through a conductor is constant, providing all other influences such as temperature are kept constant."Full Answer >
