This classic John Drummond test lamp is fuse protected and complies with GS38. So the Drummond MTL7 voltage test lamp is ideal for low cost voltage testing.

The MTL7 voltage test lamp gives clear positive indication of the presence of voltage and is not sensitive to the presence of low voltage interference.

Range 80 to 500 Volts

Drummond lamps are widely specified by electrical utilities and other large, safety conscious organisations
