I have no link to pictures of the ceramic fixtures, but they are VERY easy to find at Home Depot, Lowes, or any hardware store that sells electrical. They are only about three, maybe four inches tall. The base is round and flat with holes to screw onto the surface you want them to go on. My uro tank is only about 18 inches tall, but my dome light is on top of the screen. Less cage height generally also means less bulb wattage needed to get the basking temps up high enough.
