Trying to find what my options are for replacing my current lighting.

I have the Pentair Fiberworks system with (2) illuminators. The fiber rope light going around the pool is so dim now you can barely see it.

I have a spot light on each end of the pool which changes colors with the rope as well. I'm not sure what type of lighting they are but they don't put out enough light to illuminate the pool.

I want to get something new and I'm not sure if I need to replace the rope or just the spot lights or both.

Any ideas?
