Check out Hilite Manufacturing. They have several and are all made in the USA. They sell through several online places offering nice discounts. I have played with these and own 1 so far (I have quite a few more on order). They are well made!

Fully adjustable pendants are sold by rejuvenationhardwre.com e.g. see Brightwood Item # AA 0110 In addition these lights are sold with diverse shades or with no shade. So if you don't like the shades they have you can find separate shades. The fixtures have the classic (old fashioned) shade holder in typical sizes. Schoolhouseelectric.com also sells period shades with sized fitters. It is not entirely clear to me how adjustable the length is. They ask to the nearest inch. I found them to be very helpful by phone when I had questions about other things.

nanapeg - your'e right , they aren't on the hudson valley website, but we ordered them through a local lighting company who did get them from hudson valley, so I have no clue why they aren't on their website. mary - they're not really bronze looking at all - very dark - but we're going with a darker hardware. heimert - we're about 1/4 and 3/4. To me 1/3,2/3 looked too close together too.

I love the lights and the turquoise kitchen. Glad to hear that you found the supplier. Not to hi-jack the thread but for those interested in the coffered ceiling, we actually just did our own a few months ago. Cost was about $750 for supplies. I've included a link for anyone interested. Here is a link that might be useful: Dining Room Makeover
