I recommend butyl tape, not sealant. It's removable, it can't "fail" like sealants can, and it's cheap. I used to be a commercial high-rise caulking contractor, so trust me-it's the best choice. Just trim off the excess after you tighten the light down. That'll help keep things clean.
I too use butyl tape for most of my caulking needs. It is seldom I use anything else, but if I do, it is Parabond.
There are two different types of putty tape, the inexpensive and the Butyl. The butyl does not dry out and harden, and is very sticky.
