The electrical specifications shown are determined at a basic temperature of 25°C. LED circuit is isolated and

requires an external power source. If the source voltage exceeds the rated voltage, a ballast resistor is required.

Base of AT634 and AT636 is Black for 5V, Light Blue for 12V and Gray for 24V.
