These poles are along Rte. 2 here holding M-250R2s now. They used to have 400w MV M-400s a long time ago. The last one got replaced a year a go by a new M-400, 400w HPS
Nice Form 400s! Yep they look well maintained. However the CMHs wont work on mercury ballasts you will need to put in metal halide ballasts to get enough OCV.
do retrofit CMH Lamps last as long as Regular CMH Lamps?...the reason i ask is i know Retrofit HPS lamps have much shorter lifespans than standard HPS Lamps.
and yup good paint job...i noticed that too,they really took their time.
