4 light fixtures are very much more expensive than 2 light fixtures and then theres the cost of the bulbs. You don't really need four lights You just need a 2 light fixture with wider wings. I have 2 with a 13 inch width on a table 3 feet by 4 feet and they work very well. I can get 6 trays under them. The ones in the center get a bit less light but I move them around every time I water. I have them connected to a power bar and that's plugged into the wall. I have seen them with a 9 foot width and that would be fine on a shelf. The major thing when buying lights is to have wings so the light is concentrated downward. I would check all the hardware and big box stores that you have in your area on line. You might be able to find some on sale and them you can go into the store. As for shelving look in resale stores or second hand stores and think outside the box. Remember you have to hang the lights on something so I'd stick to wood

Oh, I cut and pasted the chandelier you posted and put it on my desk top. Then I used images.google.com and added the image. The chandy came up right away. Images doesn’t work all the time, but if you are lucky and it works, you have your answer in seconds. I wasn’t going to tell you ‘cause I wanted you to think I am a design magician. )

I have that same light in a breakfast nook & i just recently added pendant lights in very close proximity. Like you I worried about matching but These 2 colors ended up looking great together. I would have liked to have added some of the aged brass color but I needed the darker bronze shading to help tie my areas of decor together. This info may not be helpful since you are looking for a sconce though.

Thank you. I will send photos next time I'm there. It is still under construction and, anticipating your next question -- no, I cannot have the builder customize it.
