What is the term for the large ball shaped lights that are used to illuminate roads during construction?


I see the large lights used for illumination at night, but they are shaped
kind of like a round ball and powered with generators. Thank you.




I think most people who are not in the construction industry just call them
ライト (or something like 工事現場のライト).

If you really need a specific term for that purpose, you can use
[投光器【とうこうき】](https://search.yahoo.co.jp/image/search?p=%E6%8A%95%E5%85%89%E5%99%A8&ei=UTF-8)
or
[作業灯【さぎょうとう】](https://search.yahoo.co.jp/image/search?p=%E4%BD%9C%E6%A5%AD%E7%81%AF&ei=UTF-8).
