The lamps are available for 12 and 24Vdc and 110 and 240Vac use and come in three versions: ‘standard’ PL16 and PL22; PL16-AI and PL22-AI that incorporate anti-interference technology to prevent the false illumination found in standard LED pilot lamps; PL22-LT lamp test version.
Differing from the standard PL22 LED pilot lamps, the PL22-LT incorporates a third connection terminal that is used to test the LEDs in situ without having to energise the whole panel.
All of the lamp versions are manufactured from flame-retardant ABS material and are available in the high visibility ‘pure’ colours of red, yellow, blue, green, and white. They consume much less power than incandescent types and have a life of 30,000 hours.
Installed in a panel, they achieve an ingress protection ration of IP65.
