Lite4 Outdoor Lighting I didn't install these particular lights, but I do install them quite frequently . There are a number of manufacturers that make these in halogen and LED configurations. They are typically called a rail light or hardscape light. I would be careful about installing them that close to a spa, typically for code you would need at least 10' of distance between the fixture and the pool/ spa. Check your local codes on this though. In your situation you may want to go with a fiber optic source with the same effect. There are options available for this purpose.

McKay Landscape Lighting They are copper seat wall lights under the precast cap. Only if the fixture is protected from getting wet. If the bulbs get wet they will burn out quickly.
