Free Information About Health and Wellness! Lamp and Lighting Facts By: Jim Hoyle A- Thomas Edison did not invent the light bulb.   He bought the patent and improved it. B- 3 way light bulbs work like this:     1st click - The smaller filament is turned on alone creating the lower light level. 2nd click - The larger filament is turned on alone (and the smaller off) creating the higher light level. 3rd click - Both filaments are turned on creating the highest light level. C- 3 way light bulbs burn out faster because:     Alternating cooling/heating of the two metal filaments shortens their lifespan. D- Watts is not a measurement of light output. It is the electricity usage. E- Lumens is the measurement of brightness or light output. F- 2 way lamp has two separate bulbs with 2 levels of light.     (Hoyle Fine Lamps have optional hi-lo in-line switch that provides 2 levels of light from just a single ordinary bulb.) G- 3 way lamp has a 2 circuit socket and bulb that provides 3 levels of light (B above). H- 6 way lamp has a combination of 3 way lighting (G above) and 3 additional bulbs     which are controlled by a 2 circuit switch: 1 bulb on, 2 bulbs on, 3 bulbs on, then off.  I- Lamp Finial is the very top cap piece that sits on top of the shade. J- Lamp Harp is the "U" shaped wire piece that holds the shade onto the lamp.  K- Lamp Harp size must be matched with the shade size for a proper fit. L- Lamp Shades are measured: top diameter, bottom diameter, side length along with a description of the shape.
