I have a pot hanging rack like that, if I had another couple feet of ceiling height I would consider it, as it is, I'm trying to design them to get right up to ceiling as close as possible.QUOTE]
It would be a bit of work, but if you have a traditional dry wall ceiling with some space above it, recessed individual cobs would be neat. The standard canisters for traditional recessed lights come in a selection of sizes and there are motors made for the raising and lowering, opening and closing of window blinds that could lower and raise them at the push of a button.
