I have a fiberstars pool light that is broken. I was looking at different light sources for the fiber and came across this 72 led color changing light atThe fiber I have, and I'm guessing here, is about 1/2 in diameter and probably about 75 or so strands. It's currently in a proprietary connector for the fiberstars setup.
I have a single led keychain and I can see it at the pool end of the fiber when I shine it in the other end.
Would the 72 led color changing lamp from the above site be a decent light souce? The led setup is 3 inches diameter, what would be the best way to focus or connect this to my 1/2 cable without losing too much effectiveness of the leds?
