This projector is like the ezpro so easy to convert you LED and the HD66 needs no ballast hack either it is also simple to make the bulb come on from original controls see diagram on Vortone Technics on facebook ( not covered in this video but all the heavy transformer and high voltage lamp system can be removed easily ) video to follow . This is only a temp demonstration if you chose to keep the projector as an LED change the floppy disk plastic for a heat proof material, as although there is no radiant heat from the light there is from the heat sink and the plastic will eventually melt .
