To those who know the technical names for different lighting heads, I'm curious to know what these round domed lights are called that NJDOT has been frequently using these past few decades.

The light on the left in the background is a Holophane RSL-200. The light on the right I believe is also a Holophane product, but an older version of the RSL-200. Don't quote me on that, though.
