I currently have four recessed ceiling cans or "hi hats" with GE Reveal R20’s (floodlights) in there and while the quality of light is good, it looks like the bulb is sitting a little too deep giving each one a spotlight affect. Should I use physically larger bulbs like an R30, R20’s with a higher wattage, or can I adjust the height of the existing lights within the fixture?

i know there is more to it than connecting wires so if the wattage is the same from the track light to the new fixture will they be compatable? will there be a problem going from halogen to incandescent? will i burn my house down?
