Do you have this unit in a 100 watt? Can you replace the bulb with a color changing LED light and still keep it around $300.00 dollars? I have a new 100 watt transformer that I wanted to use with this light. And if I can not change over to the LED, how expensive are your color lenses?

Hi Buddy, You could go with the 100W Amerlite 12V 50' Cord and the 12V 35 Watt PureColors LED Bulb and you would be just a bit over $300.

Light comes on and is fine, then it goes out .you can still see the color chasing just broadcasting out in to the pool. It might com back and flicker some. Where can I get paper work I did not get when I bought the light.

Hi Donald, What you have described is an indication that your pool light fixture has gone bad. Could you let us know the make and model of your light so we can supply paperwork as well as make a suggestion on a replacement.

Gave rep demensions over phone of niche, since old fixture and information was gone! Sent me an exact perfect fit! Made it as easy as I could ever have imagined! Tied a string too old wire, pulled it out opposite end, tied string to new fixture wire, pulled it back, wire nutted it together.
