Best Answer

The circuit should be protected by a 15 A breaker.

CLARIFICATION:If the wires and other components are capable of handling 15 amps (14 Ga wire or larger), you can safely protect the circuit with a 15 amp breaker.

If the circuit is a non-standard lighting device for something other than typical residential application, you should contact an electrical engineer to help you determine the proper wiring and breakers.
