Abstract
The coating on the inside of a metal halide lamp for promoting the formation of a liquid condensate film consists of particles of a refractory oxide in generally block-like or spherical or fiber-like shapes. Block-like or spherical particles should be laid down as monolayers with the distances between particles being of the order of the particle dimensions. Fiber-like particles may be also laid down as a monolayer or, alternatively, in a coating several diameters thick to form 'fiber piles' having a free volume for holding liquid which is much greater than the volume of the fibers.
