Mercury is dosed into a fluorescent or similar lamp from a container shaped mostly as an elongated flat plate, inserted lengthwise into the exhaust tube and held in place by a rib in the tube engaging depressions in the center of the plate. To permit easy insertion, the end of the plate opposite the mercury container has a relatively large through hole, leaving a thin resilient wall on each side of the hole so that insertion force is minimized.

A method of applying a longitudinally extending coating of a reflecting or luminescent material in a tubular lamp by means of a nozzle which travels along the longitudinal axis of the lamp envelope. A plurality of spraying jets are so disposed that the suspension or solution, lands on a portion of the envelope immediately adjacent to the slot to be formed.
