1960's GE M-400 without refractor. With a nice clear Mercury Lamp! Sorry for the blurry side-view pic... I took the same shot like 5 times and they all came out blurry! D: Anyway, this is 1960's? This one you can see the latch easier... Keywords: American_Streetlights

This fixture is very buzzy.

Would an M-400 R2 refractor fit this?
NiMo   [Nov 13, 2011 at 03:51 AM]
Uhh yeah. GE still uses the same glassware from the Form-400 to the current M400R2.

I remember being told a while ago that the footprint on the FOrm 400 was a bit differen't. xD But you are te expert on it so yeah I believe you.

Is this the 1950's or 1960's version of this?
NiMo   [Nov 13, 2011 at 03:58 AM]
Obviously 1960s version because of the grey paint and black reflector gasket.

If we do decide to put in the Wiki, we could have a article documenting the nuances in design over the years. Very Happy

nice picture.

There's alot of these in Allegheny Power's area.

This fixture has a LOUD ballast! I dunno why. Why would the ballast be so loud? I can hear this fixture on the other side of the building.

When I was taking the night shots this was buzzing very very loud. Must have loose coils! I wonder how loud this one would be inside...
Form109   [Nov 14, 2011 at 01:21 PM]
prehaps loose coils or more likely loose laminations...come on that was an easy one. Razz
streetlight98   [Nov 14, 2011 at 10:23 PM]
The ballast is loud becuase it's been running dusk to dawn for 50 years. Razz

I have found noisy issues to be more common on GE fixtures than other models.....

Michael, my GE M-250R (second generation) also makes a lot of noises and it's from the 80s.....
But my OV-14B which was in service for 50 years is one of the quietest fixtures I have....so it's not that.......
LilCinnamon   [Nov 14, 2011 at 10:33 PM]
The other M-400 on the end isn't loud at all. I can't hear THAT one.
streetlight98   [Nov 14, 2011 at 11:10 PM]
My OV10 is dead silent. Shocked (OK, not dead, but it is silent. Laughing ) My NOS M-400 is almost as loud as a microwave! Not quite, but almost.

My 1965 GE NEMA was the loudest of all... But I fixed it with Elmer's glue!
joe_347V   [Nov 14, 2011 at 11:59 PM]
The original ballast in my R47 was much quieter than the Advance that I replaced it with. The Venture that I replaced the Advance with is quieter than the Advance but is still louder than the original one.
streetlight98   [Nov 15, 2011 at 12:04 AM]
elmer's glue? How does that work?! Shocked and yeah, Advance ballasts I find to be noisey, but one of the best quality replacement ballast companies on the market IMO.
LilCinnamon   [Nov 15, 2011 at 12:05 AM]
Another posibility: The ballast could be lose in this fixture. xD
streetlight98   [Nov 15, 2011 at 12:12 AM]
could be. The door or reflector could also be loose since the refractor is gone. My M-400 split door is louder without the refractor since the door rattles. The door has a little wiggle room that the refractor seals up.
LilCinnamon   [Feb 09, 2012 at 02:02 AM]
I think the Original M-400 had the same top housing as the M-1000, the shape looks VERY similar and the attributes.
