Lot of 4 vintage explosion proof industrial lights. These lights currently need to be hard wired. There are two with white porcelain tops and two have heavy black plastic tops. All the lights show wear and marks throughout and could use a good cleaning. One of the porcelain tops has a small surface crack but the more I look at it I think it was a factory thing as it does not go through and the top is still extremely sturdy. One of the shades on the black pair has paint on the bottom of the shade. The black pair is marked "Crouse-Hinds Made In Canada V-75". Re-wired these lights have lots of possibilities as individual lights or hang them offset all together as an interesting ceiling light. Each light is approx. 8 1/4" long. Please pm me for additional pictures.
