DIFFUSERS AND DIFFUSER SHADES

 
Table Lamp with Diffuser Diagram at The Antique Lamp Co.

Floor Lamp with a glass bowl called a Diffuser at The Antique Lamp Co.

Diffusers are a glass "bowl" which forces the light upwards providing bright, indirect lighting to illuminate a room.

Diffusers are also called the I.E.S. reflectors because of the development of Illuminating Engineering Society (I.E.S.) standards which encouraged better lighting in America through higher wattage output and the development of the 3-way bulb.

Many people think that the diffuser IS a shade in itself and look for one that is fancy or colored. This is not the case. A diffuser is simply a glass bowl that is made to diffuse the light upwards. A fabric shade then sits on top for aesthetics and to soften the glare from the bright bulbs.

Floor lamps with a 3 candelabra sockets around the diffuser are the most common and popular type of lamps that take a diffuser. Diffuser lamps are still very popular today because of the great light they provide. They take large "Mogul" bulbs in the center which are very high wattage and therefore, are a powerful light source without being harsh.

Diffuser Shades

Diffuser shades simply sit on top of the glass diffuser with notches to keep it centered. They're designed to hide the diffuser and soften the candle bulbs' glare.

Size tips: The top (T) measurement of a diffuser shade should be 1" or greater than the diameter of the diffuser itself. In general, the bottom (B) measurement of this shade for a 3-candle floor lamp should be 18" or greater.
