I can confirm it is not the bulb....I had ordered a replacement bulb and was in process of replacing it. It is a 120V light. I have 120V as the junction box but nothing at the light. Internal to the light there is a "metal" cap that appears that it covers a "circuit" that would trip the breaker if water was in the light cavity. The cap easily (too easily) popped off and i found the "circuit" is rusted beyond repair. (Obviously some water had gotten it at one time - I should note that the light cavity was dry when I went to replace the bulb). Note - the retaining screw is slotted....I would like to replace the light housing. But since the Startlight series is old, I cannot find a replacement part. I am looking for advice on what replacement assembly will fit in the existing niche.
