200mm long Standard
The majority of Arcolectric indicator lights can be supplied with alternative light sources:
Neon, Fluorescent, Filament lamp or LED.
NEON and FLUORESCENT LAMPS
Colours
Available with Red, Amber, Green, Blue or Clear lenses.
Maximum striking voltages
Standard brightness types 65Vac 90Vdc.
High brightness types 85Vac 135Vdc.
High brightness types are usually fitted.
Life
Typically 25,000 hours (Green fluorescent lamps 20,000 hours). (Measured to
a point when the light output of the lamp is half its original level.)
The end of life for a neon lamp is not usually a sudden failure.
False signals due to long wiring
It is possible for neon or fluorescent tubes to glow when they should be off. The
false signal is caused by the capacitance effect of fairly long wiring to the
indicator being adjacent to other live cables. This effect can be prevented in
most cases by fitting a 100k resistor across the supply wires close to the
indicator assembly.
