1. Types of Light Bulbs and Their Uses

2. Bulbs
There are many different types of light bulbs around, and they were all designed with a certain use in mind.

3. Incandescent Bulbs the most familiar and standard bulb
produce a steady warm light
used in many household applications
can last for hours
produces a yellow light

4. 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

5. Incandescent Bulbs

6. 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

7. 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

8. Halogen Bulbs

9. 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

10. 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

11. Fluorescent Bulbs

12. 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
