mercury-vapor lamp

Its main use is perhaps as a component in Mercury-vapor lamps.

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

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

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

Mercury-vapor lamps are more common in the laboratory.

In medium-pressure mercury-vapor lamps, the lines from 200-600 nm are present.

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

The blue ones are mercury-vapor lamps.

A mercury-vapor lamp is a special lamp.

Mercury-vapor lamps and sodium vapor lamps produce light from atoms in excited states.

Randy's eyes adjust, and he can see now that he is staring into a cavern, lit up by mercury-vapor lamps.

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

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

High pressure mercury-vapor lamps.

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

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

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

In 1901, Peter Cooper Hewitt invented and patented the mercury-vapor lamp.

Thallium(I) iodide is used in mercury-vapor lamps.

In mercury-vapor lamps and fluorescent lamps.

The current clicked off; the mercury-vapor lamp went out; the shades were parted and the two stared at each other ner- vously.

Earlier in the day, he had broken the single mercury-vapor lamp in the immediate area, so his movements now were in near-total darkness.
