Switchtec's PL22 range of LED pilot lamps offer clear benefits over traditional filament lamps, offering very low power consumption, robustness and bright illumination. The 22mm lamps operate on a range of ac and dc voltages (tolerating +/-20% deviation) and consume less than 20mA. Available red, yellow, blue, green and white, the PL22 offers an ingress protection rating of IP65. The standard 22mm cutout means that the lamps can be retrofitted to older designs of panel incorporating filament lamp units.
