Response to Hi, Mike. Yes, this Hayward Lens Gasket - PL5850 will fit the SP0853L30 fixture. There is not a LED bulb that is equivalent to a 500 watts incandescent bulb. We have the Pureline Purecolors LED Bulbs, Item # PL5814 and PL5809 or the Pureline Purewhite LED Bulb, Item # PL5849 that is compatible with the Hayward SP0583L30 fixture.
