So far i havnt found 12v 20 -25w halogen housings, such and gardening lights and what not, so i thought i might go with one 55w fog light or somthing like that for cars... i can get 2 but ill need an 8Ah+ bat and thats heavy. So if i run one 55w light and a 5-6Ah 12v batt i should get 1 hour run time, right?!?
