It would be good to figure out the layout of the ceiling joists and other obstructions above the ceiling as those will impact the layout and the total number possible.

If the number of holes becomes too large, other lighting forms may be better suited. The installation costs may become predominant and make the project in feasible from a economic perspective.

Check out selux.com for some ideas.

Thanks for the link I'd never considered a product like that. They do look a bit industrial/commercial for a kitchen, but are obviously way better than a traditional fixture.

Unfortunately, I do have a rather long rectangular space. It is roughly 12.25 x 26.5 feet, with the joists running parallel to the short dimension. We don't believe there are too many obstructions in this ceiling, as the HVAC is coming from the floor. Half of the space is already run with some existing 4" incandescent cans. I'll have a conversation with my GC this week during our planning meeting to review ways to simplify the overhead lighting plan.

I'd say bigger cans, fewer lights. 4/3/4 sounds better than 6/4/6.

Note you shouldn't use PAR30 bulbs if you want a wide flood. I did side-by-side comparisons and PAR was rather focused and cast definite shadows -- I'd go with BR30 for a flood.

It's all design preference tho. If you were to do the Elco, I could envision there being more, smaller and in a line closer together and it could still look sharp. It might even look a bit more modern w the smaller fixtures.

Post back with what you pick, and how it looks. :-)
