I am in the process of finishing my basement and was wondering on how you install can lighting in a drop ceiling. I have been told a few different things; one way is you build some sort of brace just below the I-joist to set the can in so it sits at the grid level. The other way I was told is you simply place the can right on the ceiling tile. This way seems odd as a whole room of cans seems to be a bit heavy for a suspended grid system. Any suggestions??
Halo cans are designed to clip directly to the grid, cut the hole in the tile, install the tile then install the can. As you said if there are alot of lights they could get heavy, make sure there are an adequate number of support wires on your ceiling. These grids can hold alot of wieght when done properly, alot of industrial buildings use the grid to hold either lay in flourescents, or surface mounts, and the ballast alone in these fixtures weighs more than a can light.
