Abstract
A ballast tester for HPS lamp circuits includes a body of insulating material, a base which fits the lamp socket, a single wire connected to the base and extending through the body forming a loop, and a hole in the body within the loop to receive a clamp-on ammeter. The ammeter measures short-circuit current, giving an indication of ballast condition.
