I have a question about standard mogul and medium base light bulbs. First of all i bought an old floor lamp at a thrift shop and it uses a light bulb which has a large base on it . From what i learned it a standard mogul base. Nobody in all of west texas has a replacement bulb. Do they even exist anymore? Do they make adaptors to convert biggen bulbs to smaller bulbs? Or what would be my best option?

I recently installed track lighting but the dimmer did not work. I replaced the dimmer with a switch and still the light does not turn off? what do I do to get it to work. the wiring for the light is as follows: two white wires, two black wires and one red wire. upon wiring the track light, I noticed that only one white wire would allow the light to work. if I used the other white wire it would not go on. the original light fixture used the two white wires together and the two black wires together. the red wire was capped. the track lighting had a spot for a ground which I assume is the red. I get a reading using a voltmeter from red and black and also from white and red, therefore I assumed that the red is ground. as for now I have to turn the circuit breaker off when I want to turn off the lights. the light switch is next to a switch that controls the outlets in the living room. there is only two wires on the outlet switch black and red. the black wire comes out of one switch and goes on to the next switch. the one red wire is connected to the outlet switch and a new red wire is connected to the light switch. Any suggestions
