I've got a box of sockets like this:
I was planning to mount a few of these on the ceiling, but am wondering about safety since the hot wire is essentially exposed, and would be very close to one's fingers when changing a bulb. I stopped at the hardware store and saw sockets just like these, except they had cardboard around the upper portion. Would I be ok wrapping electrical tape around the upper portion, or does anyone have better ideas? I also thought about wrapping tape on it then putting a cover like this over it. Thanks.
