light phosphor vapour

A lamp consisting of a tube, coated inside with fluorescent material (phosphor), filled with mercury vapour, and with an electrode at each end. Light is generated by passing a current between the electrodes through the vapour, producing ultraviolet light that is converted to visible light by phosphor fluorescence. Such lamps are more efficient than filament lamps.
