A CMH R47??? Here's my R47 after a quick retrofit from 250w MV to 70w CMH, The CMH lamp that I have is a medium base one so I had to use a socket reducer and a socket extender to centre the lamp. The ballast is the same one in the ballast tray that I posted earlier today. The R47 looks pretty good in CMH, it even looks a bit like a /DX merc from afar although MV looks a bit blueish and is a bit greener (the lamp actually looks more like [url=http://www.lighting-gallery.net/gallery/displayimage.php?pos=-42858]this[/url] when lit). Looks like CMH retrofits quite nicely into existing streetlight fixtures IMO. Keywords: American_Streetlights

Looks interesting!

Thanks, too bad the utilities don't use CMH.

Yeah, CMH is good stuff from what I hear. I haven't seen it yet in person.

thats a real nice retrofit.

I bet this isn't as bright as a 250w MV though.

There are now CMH street lights here in Southern California. Smile

Cool, I don't think any utilities here use CMH to the best of my knowledge.

Is CMH lamps more $$$ than regular PMH lamps?
joe_347V   [Aug 18, 2011 at 11:23 PM]
I think they're more expensive but if you buy them online you can get a 70w CMH cheaper than what the box store would sell a 70w quartz MH for.

This one came with a 50w MH recessed light from Restore though.
Not sure why they put a 70w lamp in...

Did your 250w ballast die or something? Or was it just too bright?
