LED COLORS & SPECIFICATIONS

The electrical specifications shown are determined at a basic temperature of 25°C.

LED circuit is isolated and requires external power source. 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.
