Preferred Label : low-pressure mercury lamp (arc);
IUPAC acronym : -A;
IUPAC definition : resonance lamp that contains mercury vapour at pressures of about 0.1 Pa (0.75 x 10E-3
Torr; 1 Torr 133.33 Pa). At 25 C, such a lamp emits mainly at 253.7 and 184.9 nm.
They are also called germicidal lamps. There are cold- and hot-cathode as well as
cooled electrode-less (excited by microwaves) low-pressure mercury lamps. The Wood
lamp is a low-pressure mercury arc with an added fluorescent layer that emits in the
i UV /i -A spectral region (315-400 nm).;
