This is a very unusual industrial or nautical lamp.  Found in rural far East Oklahoma.  The aqua box has a single socket.  There are 3 angled mirrors at the back to intensify the light.  Appears to be a wall-mounted fixture.  The remnant of a paper tax just in front of the socket is no longer legible. 

Dimensions: 7" Wide X 7" Long x 6" Tall (total) / Light box is 6.25" Wide x 6.25" Long x 5" Tall. Sockets are 1.5" diameter as measured from the outside x 2.25" Tall.      

Unpacked weight: 3 pound 5 ounces

Condition: Good usable condition - ideal for your replacement needs.  Metal is rusty, chippy, and corroded.  Left side panel has visible bend.  Mirrored back panel tops are roughly cut off.  I am not an electrician - but socket and wiring look serviceable to me.  Obviously, will need to be wired into desired mount.  No mounting hardware.

Always happy to pass through discounts on combined shipping. I only charge actual postage, and always use recycled packing materials. 

Note some photos appear redundant because I take photos from all possible angles.  On symmetrical items, these photos may appear redundant when there are no distinguishing differences or condition issues between side views.

I gladly accept returns, but please note I do not pay return postage unless there was a significant error in my description.  The item listed is being sold as is, as pictured and as described to the best of my knowledge. All dimensions and weights approximate. If you have a question or an assumption on an item prior to purchase, please ask. I much prefer to take the time on the front end to make sure you will be satisfied with your purchase.

Remember, when buying vintage expect imperfections as these items have a history and have been in the possession of others. I try to list EVERY flaw which would be commented on something in an antique or vintage condition – this does not mean all imperfections resulting from normal wear & use require comment. My goal is to have no rude surprises upon receipt.
