Product Details

Filament Test Lamps Drummond MTL7 and MTL9C

Two filament test lamps giving safe indication of voltages between 150V and 500Vac/dc. Their robust design meets the recommendations of the Health and Safety Executive in their guidance notes on electricians test lamps (GS38)


The lamp housing, moulded in hard rubber, contains the 15W rough service SES pygmy lamp. Both the lamp housing and the probe contain a 500mA HRC fuse, have a finger shield and removable insulated probe tip with only 2mm of exposed metal. The probe handle contains a 4000Ω series resistor. A two layer double insulated cable with white inner insulation gives a clear warning of abrasion that might compromise the users safety, and is resistant against flame, heat and oil. To enable use in most circumstances a right angled probe tip is supplied in addition to the two straight tips. For convenience a small pouch is attached to the cable for storage of the probe tips.

MTL9C Additional Features

The MTL9C incorporates a test circuit, totally enclosed in a small moulded case and mounted on the cable. This continuity tester indicates continuity in the test lamp circuit and thus warns of fault conditions such as a blown fuse or broken filament lamp, (this test ignores the presence of the LED circuit).


Test lamps should be proved safe before and after use, by testing on a known live circuit, using the continuity tester, or through the Martindale PD690 proving unit.

Martindale Proving Units

The Martindale proving unit has an output voltage rating of 700VAC. It is compatible with voltage indicators, including the new VI-15000 and VI13800.
