mercury-vapor lamp

In low-pressure mercury-vapor lamps only the lines at 184 nm and 253 nm are present.

High-pressure mercury-vapor lamps are those lamp commonly used for general lighting purposes.

Low-pressure mercury-vapor lamps usually have a quartz bulb in order to allow the transmission of short wavelength light.

A mercury-vapor lamp is a gas discharge lamp which uses mercury in an excited state to produce light.

However, single-element light sources, such as sodium- or mercury-vapor lamps have emission lines with quite narrow frequency spectra.

The mass of tangled wires, the current leads, the mercury-vapor lamp up above meant nothing to it.

The mercury-vapor lamp went on and Haridin pulled the window curtains together.

The mercury-vapor lamps shed far more light than traditional quartz-halogen ones, illuminating large expanses of the wreck for the first time.

General Electric once made mercury-vapor lamps in the building.

The blue ones are mercury-vapor lamps.
