Try companies that make bathtubs for RVs.

2. Yes, LEDs will be cooler. The typical height for direct wired Ucl ranges from .75" to 1.25". The smaller the profile, the higher the cost. There are panel lights. None of the good options can be obtained from HD or Lowes. Gaps in the illumination can be minimized with direct wire Ucl like UniLume where the output is sufficiently high and diffuse. The DIY Ucl and continuation threads have more info and the question about corners is answered there. The bars have to be perpendicular to avoid shadow zones.

In most areas code is tight where you cant fit a 4" sphere between them.

suzi-yes that's right they are rectangle. And I am aware that I'd have lost a triangle (that would be my wasted space that I didn't need for anything) - and the circle in the rectangle does have some wasted space on the 'corners' anyhow. I thought it out and was prepared to do that. I just offered up what I have and what I contemplated as an option in case it was helpful for the OP. I would have been more than happy to do so and it would have housed the stuff that I have in my kitchen just fine, wouldn't have missed it a bit and susans are pricey. Some people love them, some people like them and some people just don't have them. You don't have to have a susan as a solution. Space calculations have been done showing that it's not really the loss of space that it can appear to be. I am okay with not preferring them even though many or even most enjoy them and find them useful. closing-off-a-blind-corner calculations beth09-I know it! I actually have a drawer stack that's somewhat empty - hahaha. It is a shock to the system. You will find what works for you. I will say the super susan (no pole) pie shaped does seem much sturdier than my old regular susan with pole.
