I have a American Products pool light model Aqua light 98711300. Its  a 120 volt 250 watt  fixture. The fixture is old and rusted. I would like to replace the whole fixture while upgrading to a  color LED lamp. What are the options that would fit my existing alcove. I would also be interested in switching o 12 volt for safety. The pool is 22x 40 lazy L so I do need a fairly bright light because the only light is in the entrance steps
