The electrical specifications shown are determined at a basic temperature of 25°C. LED circuit is isolated and requires an external
power source. Single color LEDs are colored in OFF state; bicolor LEDs are translucent white in OFF state. Polarity marks are on the
switch. If the source voltage exceeds the rated voltage, a ballast resistor is required. The resistor value can be calculated by using the
formula in the Supplement section. Additional lamp detail is shown in the Accessories & Hardware section.
