Bulbs There are many different types of light bulbs around, and they were all designed with a certain use in mind.
Incandescent Bulbs the most familiar and standard bulb produce a steady warm light used in many household applications can last for 700-1000 hours produces a yellow light
Incandescent Bulbs electricity heats a tungsten filament in the bulb until it glows filament is in a vacuum or in a mixture of argon/nitrogen gas energy consumed by the bulb produces heat low Lumens per Watt performance surge of energy causes the filament to break
Halogen Bulbs produces a brilliant white light more lumens per watt than incandescent never touch glass small in size and are dimmable more expensive high temperature and possible fire hazard
Halogen Bulbs electricity passes through a tungsten filament filament in a glass tube containing halogen gas halogen gas causes a chemical reaction removing the tungsten from the wall of the glass and deposits it back onto the filament
Fluorescent Bulbs long bulb life 10,000 to 20,000 hours very efficient produced very little heat cannot be used with dimmers need components called ballasts to provide the right amount of voltage casts green light or blue daylight
Fluorescent Bulbs electrical current passes through a tube filled with argon gas and mercury this produces ultraviolet radiation that bombards the phosphorous coating causing it to emit light
