Fiberstars F4

[azdaren]

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.

Thanks,

If there is enough slack, I would re-terminate it. If there isn't, you'll have to dig a bit to get the base down a bit to make slack. The 1/2" won't make a big difference but a clean cut with a hot knife tool and a little fiber gel will go a long way to restoring the light. It's also possible that the fiber yellowed if it cam into contact with the chlorinated water. This would require replacing the affected bundle.

Thanks Scott,

Im thinking I will try re-terminating at the illuminator.

Both the light in my spa and pool are dim, so Im guessing the problem is at the illuminator.

Thanks,
