Electrical specifications are determined at a basic temperature of 25°C.
LED circuit is independent of switch operation. If the source voltage is greater than rated voltage, a ballast resistor is required.
The ballast resistor calculation and more lamp detail are shown in the Supplement; see Supplement Index (page Z1).
