The " Sol " Photographic Lamp.

For magic lantern or photographic enlarging work when no gas or electric light is available, the " Sol " lamp provides an extremely serviceable and widely-used alternative. It gives an intensely

brilliant white light, produced by an incandescent mantle m comunction with a combustible gas. This gas is generated by heat from a supply of methylated spirit contained m a seperate reservoir, and the intensity of the light can be regulated by raising or lowering this reservoir. It will burn continuously for two-and-a-half hours, at the cost of a few pence. In the latest model manufactured by Houghtons Ltd., of London, the mantle can be easily removed without fear of breaking. The old models will not permit the

removal of the mantle very readily, and there is considerable risk attached to the operation. A small spring is fitted to the burner, which engages in the draught holes, and keeps the burner in the correct position. To remove the mantle this spring is disengaged and the burner lowered, allowing the mantle to be easily removed. This lamp can be used on a lantern tray as well as on an ordinary base, and can be used with or without a reflector.
