What does the NEMA tag look like, all red or half red/half white? If it's the latter could you get a chot of one of the tags? I've never seen a PSMH Cooper tag.

I'll bet these aren't bright either. I'd personally use 100W PSMH for a road like that or at the very least 70W PSMH.

Its all red with "MH" on the corner I believe. With the '5' number. The bulbs are medium base. Also, in another town in MA I saw what I believe are 35w HPS. Pretty dim!

Ahh. It seems AEL and Cooper still use probe start tags for PSMH lamps under 175W while GE uses PSMH tags down to the lowest wattage lamps. I'd imagine a 35W HPS light is a flashlight compared to 100W HPS. Laughing

Remember, all wattages 100 and below NEVER had probe start, so there is no confusion in that part. So this may be why they do not use PSMH tags as of now.

I still stink it's somewhat confusing. That's like using MV tags for HPS wattages under 100. I prefer the fully red tags anyways but the proper tag should be used IMO. Neutral

Concord is also a municipal utility.

You still "stink" Michael? Razz

Think about it....100 watt was NEVER used as probe start, so it's impossible to accidentally put a probe start 100 watt in a 100 watt pulse start cuz you don't know if it's 100 watt probe or pulse because probe start 100 watt simply does not exist....

However 175 watt pulse and 175 watt probe both exists...so they separate it. But both are STILL MH....the red saying its a MH and white just adds a pulse characteristics of this certain wattage...

Yep i still stink. Razz Laughing
Yeah but doesn't it make more sense to make them all uniform by having all the PSMH bi-color?

There are some M-400s in Garden City Shopping Plaza that are 320W PSMH (older ones from like before 2007) and they have fully red tags but that was before the bi-color tags came out.
