Does anyone have a source for low voltage lights, such as flood or spot that have lenses that can be changed to green or blue and such? Only ones I can find are direct plug in where each light gets plugged in to a power source, remote control lights that use RGB lLED's but always revert to white when powered off and back on again, I tried using glass paint on the under side of the glass lenses, many, many coats but they fade within weeks and back to almost clear. I have 12, 8 ft artificial palm trees" Yup-fake, tried growing real, no luck " that I light up the fronds with, but getting tired of the white lights, too much white " Griswold" going on in my yard. Just looking for a 12 volt AC light that I can connect to already buried cable .
