Fluorescent lamp at each end there is a filament lamp tube has a thin trace amounts of argon and mercury vapor, on the inner wall of the tube is coated with phosphor, conductive filament between two gases when ultraviolet light, the fluorescent powder gives a soft light.
Characteristics of fluorescent lamps: lamp starts lighting requires a higher voltage, normal light only allows a small current, when both ends of the lamp voltage is lower than the supply voltage.
