SIGNALLING LAMPS
Signal lamps Ø30 type NEF30-L or D30 with metal body and Ø22 type L22 or D22 with plastic bodies are designed to be built properly into Ø30,5 mm or Ø22,5 mm holes in consoles, control desk or in machines and equipment.
Signal lamps may be used my in various climate zone (N/2, W/3), in any position under roof in industrial conditions with environmental pollution degree 2.
In respect of luminous element signalling lamp can be devided into:
- signal lamp with bulbs,
- signal lamps with LEDS
Signal lamps are supplied as complete products in accordance with orders.

Notice:
When lamps with LEDS are connected with long wires, then is possible phenomenon of slight shining without supply voltage. This is result of induced voltages in long wires going along wires conducting high currents. To avoid this phenomenon one should disconnect both terminals of signaling lamps.
