I agree. You might be surprised with what you are able to find out. I wanted details about an oversize tub in a resort that we stayed at a few years prior. I was referred to the interior designer who handled the most recent renovations and she pulled out her source file to answer my question. The bonus though was the front desk guy volunteering to go into one of the rooms and text me a picture of the tub! It wouldn't hurt to ask... that is a very cool shelf fixture.

That appears to be an alabaster up light. I don't know where you can find a replacement canopy. Can't imagine how the canopy could be damaged unless the fixture was simply pulled off the ceiling. Do not use high wattage bulb in this fixture as the stone can discolor from heat.

Check EF Chapman Lighting

Well, if you bought them without much info, you can probably sell them without much info too. I like the look of them and would be tempted if I needed them. Good luck!
