What years did MV nema heads come out in? Did they come out before the cobraheads or after. Theres only a few 100 watt MV nema heads in my town, so I would assume they only installed them for a little bit.

They came before cobraheads. The current common bucket style started appearing in the late 50s/early 60s and the other ones, like radial waves and crescent moons I think date back to the 40's. The FCO NEMAs that are a little less common were first made in the early 2000's when the whole dark skies thing happened.

Ok thank you, there’s only a few Nena heads that are power company owns and there only in residential neighborhoods.

Also what are the names of the Nema heads?
