Types of Light Bulbs and
Their Uses
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
Incandescent Bulbs
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
Halogen Bulbs
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
Fluorescent Bulbs
Compact Fluorescent
like fluorescent bulbs, but in a much smaller package
produce little heat and are very efficient
cannot be used with dimmers. last up to 10,000 hours
Compact Fluorescent
