I think these look great too! And if they want to keep up with the latest technology they could make them CMH!
streetlight98   [Sep 09, 2011 at 08:19 PM]
They actually did a dood job painting too. No streaks or missed spots and no paint on the refactors.

@niall i haven't seen these at night...i suspect they are still Mercury Vapor,but yes CMH sounds like a FANTASTIC idea!

and yup good paint job...i noticed that too,they really took their time.

How many poles are in this lot?
Form109   [Sep 09, 2011 at 10:22 PM]
This is the only pole...it's a fairly small lot.
streetlight98   [Sep 09, 2011 at 10:24 PM]
Could you post a pic of the whole pole?
Form109   [Sep 09, 2011 at 10:26 PM]
i don't have a picture of the whole pole....i'll get a shot later if i go back to that part of town. Wink
streetlight98   [Sep 09, 2011 at 10:29 PM]
ok. Thanks. Smile

Some fixtures look good painted black. Even the Chicago Crimefighters look a lot better that way.

me personally i like a Bare Form 400,but this doesn't look bad at all.
Silverliner14B   [Sep 18, 2011 at 01:41 AM]
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.
gailgrove   [Sep 18, 2011 at 03:11 AM]
I know that Dave, I meant they could install PSMH ballasts and CMH lamps.
joe_347V   [Sep 18, 2011 at 03:37 AM]
They could also install probe start MH ballasts and run those retrofit CMH lamps which avoids having to deal with remote ignitors.
Form109   [Sep 18, 2011 at 06:20 AM]
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.
streetlight98   [Sep 18, 2011 at 02:22 PM]
I think in any retrofit situation, the retrofit lamp won't last as long. The longest life is achieved by the regular ballast and gear.
gailgrove   [Sep 18, 2011 at 02:27 PM]
Guys I said install PSMH ballasts, not use retrofit lamps...
streetlight98   [Sep 18, 2011 at 03:04 PM]
Yes, but if you use PMH ballasts, you need to run a remote ignitor, so it may not be as effective as using a probe ballast with retrofit lamps.
gailgrove   [Sep 18, 2011 at 03:09 PM]
HPS remote ballasts can be mounted up to 50 feet away from the lamp and I would think it would be the same with PSMH.
Form109   [Sep 18, 2011 at 09:54 PM]
remote ignitor still stinks. Razz
joe_347V   [Sep 18, 2011 at 10:20 PM]
Here's a spec sheet for those retrofit CMH lamps, they're rated for 20,000 hours. How does that compared to regular CMH on a PSMH ballast?
