vertical fluorescent lantern

Appearance, elegance and slim modern lines are the dominant feature of this lantern. With its all-round distribution of light, its main use will be for lighting avenues, promenades, ornamental gardens and those streets which are the object of particular civic pride.

Specification

Special Features. In this lantern the plastic diffuser and cap are manufacturered as one piece which stands on a small ring gasket at its lower end. By means of a large clamping screw, which passed thorugh a gland attached to the cap, the diffuser is tightened down on to the gasket, thus virtually achieving an hermetic seal. In this way, no attention is needed between tube changes - an infrequent operation with the long, reliable life of an ATLAS fluorescnet tube.

The Gamma One lantern incorporates quick start control gear (except the PF capacitor) for four 5 ft. tubes.

Materials. The diffuser is manufactured from opal plastic sheet, the cap being of the same material but coloured and cemented to it. The base is a substantial casting of corrosion-resisting aluminium silicon alloy.

Finish. The diffuser and cap are treated with an anti-static compound. The base is "Bonderite" processed and stove enamelled grey.

Installation. The Gamma One lantern requires a spigot 3" in diameter by 5" long which is gripped by three 3/8" B.S.W. set screws in the base.

Lamps. Four ATLAS 5ft. 80W White Tubes or ATLAS Low-Temperature Tubes.
