Quaray 10 Inch Plastic Bowl Lamp Shade for Torchiere Floor Lamp, White, B250

Model: Quaray B250 Material: Plastics (note: not glass) Color: White Dimensions: Opening Width: 10", Height: 4-3/4", Center Hole Diameter: 1-5/8" Maximum allowed bulb wattage: 100W To check whether the lamp shade fits, as shown in the last picture, the easiest way is to measure the inner diameter of the lamp socket collar ring, which is a ring screwed over a bulb socket to hold a lamp shade. (note: the collar ring is not included in this sale.) The lamp shade fits if the inner diameter of the collar ring is in the range between 1" and 1-1/2". A 25-cent coin, which has a diameter of ~1", can be used for the size estimation. Reflected light from ceiling and walls plays a main role when using a torchiere floor lamp. In order to achieve high brightness and high energy efficiency, it is recommended to use an LED bulb. The third picture shows an example with a soft-white 9W LED bulb (equivalent to a 60W incandescent bulb) in a bedroom with low ceiling. In the fourth picture, a soft-white 15W LED bulb (100W equivalent) has been used in a room with high ceiling.
