I have an old Fiberstars Fs4 light system. The light is very weak in the pool. I know the bulb is good and I have cleaned the little piece of glass the sits between the bulb and the fiber cable.
I have attached pics of my fiber ends and my fiber cables. I have no idea what I'm looking for but it does look like the ends of my fiber are pretty dirty/worn. I wiped them but its not just dust unfortunately.
Are the fibers supposed to terminate flush with the housing, mine sit about a 1/2" lower.
Any thoughts or suggestions are appreciated.
