White Mazda Lamp - Tipped

This bulb was introduced in 1920 and probably was discontinued in 1925, the year outside frosted bulbs were introduced. As with any frosted light bulb [see A37], this type of bulb, made with an enamel coating, was manufactured to reduce the harsh and uncomfortable glare ordinarily given off by a transparent light bulb. Unfortunately the White Mazda lamp absorbed more light than would a frosted lamp and thus was dimmer and was probably not very popular either. 

NOTE: To see the filament, shine a flashlight through the bulb from the back and look for the shadow of the filament.
