A, used SwimQuip Underwater 500 Watt 120 Volt Light

This SwimQuip Underwater Pool light is contained within a heavy copper shell construction. The high-impact lens with many small prisms is designed to reflect light rays throughout the pool, eliminate undue glare from above and be damage resistant for the safety of swimmers. Marked as fresh water only. 120-Volt light, 50-feet cord length and 500-watt R40 Lamp.

Lamp is burned out.

There is some aging to the copper, wherein the copper fixture that contains the light is turning green from water contact. The glass and metal rimming around it are in good condition.
There was no continuity when checking the light. Needs new bulb.
