摘要

The outer glass envelope (1), which is evacuated, surrounds a sealed aluminium oxide tube (3), which holds an inert 'starter gas'. The electrodes (8,9) at either end of the tube, carry a mixture of sodium with mercury, cadmium or both. The niobium electrode support leads (6,7) are connected to the screw-in lamp terminal (2). A typical tube has an inner diameter of 6.9mm, a volume of 3.3cc, and an electrode gap of 7.5cm. It contains 17 micromoles of mercury, 43 micromoles of sodium and xenon at a pressure of 26 mbar. It consumes 250w and produces 100 lumens pet watt.
