Hmm. Is there some dirt/dust on this light or is the paint tone a tad uneven? The ITT 13 is a nice light. Was this style 13 ever made in silver? I swear I've seen some here with plastic lenses that are silver and are MV... There are also a couple 100W HPS versions too with glass lenses like the one above.
Now the 115s do have the heat sinks!
Funny how design goes and comes back!
