Uses an internal series resistor to drop the voltage across the LED bulb to 28 Volts.
PilotLED Assembly Part Number Example: 02 = (1-LED, 5mm); 06 = (4-LED, 5mm); 03 = (7-LED, 3mm)* Volts = Full voltage. Customer defines incoming voltage, lamp in holder is made to that voltage. This holder contains no current limiting resistor. (Example RPLH16-24-01-02 [24 Volt incoming source]) ** = 48 & 130VDC use an internal series resistor to drop the voltage across the LED bulb to 28 Volts.
