Panel lights should not create such a big problem.

Carefully position the panel light instance in the map (snapping to grid, of course), and clip around it. Be sure not to remove the brush behind the light panel. Just recess it 8 units behind the light, and this should prevent any leaks.

Better yet, after you have one nicely positioned panel, shift-drag that to copy it. Whenever you do a fresh Ctrl-V (paste), the instance does not automatically snap to the grid. Shift-drag is your best friend to avoid leaks.

Ah, but my walls aren't thick enough to be able to clip around it, normally, so I have to clip in half, create a brush for the back, and make sure the top and bottom are sealed off as well. It's just annoying.

I usually make my wall 16 units thick.

My walls are usually 16-32 units thick, depending on whether it's an internal partition or external brush that seals the map.

I usually stick to 16 units, trying to attach rooms together is what forces me to adjust the grid.
