This led hardness is used to light the Amur Bartop Waterfall on Tiger River beginning in the year 2004.
The harness is connected to a plug found on the main spa light and runs through a section of flexible PVC pipe to the side of the spa where the three LEDs clip into a fiberoptic harness which sends the light to the base of the water stream on the waterfall. To access the hardness, the side of the spa must be removed and a small amount of insulation will have to be removed as well.
The main spa LED light can be found here:
Replacement foam insulation can be found here:
