I just happened to be hanging over the edge. Because my water isn’t moving yet, I was able to see all the black yuck behind this light! What do I do? Two of them are like this.
Remove the GloBrite color light assembly from the pool or spa water: Using the provided installation tool (P/N 620057), rotate the light assembly counter-clockwise about a 1/8th turn to release the light from the niche as shown on page 11).
Frankly, I would not mess with the light. You are more likely to cause yourself problems.
