I'd say that this is a little heavy for this arm (or the thru bolt is loose) as it is pulling away from the pole. This street is a mix of AEL 115's OVM's among others only the large lights are sagging like this and have been for as long as I've seen them.The only large one not sagging are one the underbraced HAPCO arms .

Yep an OVM. Over here, they're not that common.

Good quality things are awesome. Cheaply made things are not.

That arm should have been retired years ago . I love how the bottom is digging into the pole and the top is pulling out !

City of Columbus upkeep at it's finest !!!

Good looking cobra from the side. I don't believe I have ever saw one in service.

Looks like the thru bolt just needs to be tightened. Wood poles shrink over time so it's not all that uncommon for the arms to do this. That's why the lag bolts are also important, to prevent the arm from falling right away if it slips off the thru-bolt.

This is a Joslyn arm, BTW. I have a 4ft aluminum version with JYN stamped on it. Mine is drooping at the end, as it was likely intended for remote ballast or incandescent lights but had a heavier cobrahead. This is a steel arm though, so I doubt it's really bending.

That and the base is too small for a large weight on the arm. IMO

Tightening the bolt would make a significant improvement. The city will never do it though. I'd guess this originally had a much lighter fixture such as a clam shell or incandescent .

I agree, a larger pole bracket should have been used on the arm. The arms in my area that sag the most have close thru-bolt/lag bolt spacing on the pole. The arm probably wasn't engineered for a heavy self-ballasted cobrahead.

Yeah they don't tighten the bolts here either. Around here the arm would stay like this until the pole was replaced. When the light is transferred, it would get cranked down. The utility company here gets lazy on the lag bolts though, usually only installing one lag bolt instead of two, or not installing any lags at all! When their now-recently installed pole age and shrink, the thru-bolts will come loose and the arms could fall off the pole and injure/kill people. Not a good practice IMO.

There are a few of these in downtown Tomball. Most of them have bad capacitors, which results of the lamp in the fixture not getting bright. But also CPE maybe using bad or defective lamps.

Save the Cooper OVWs!! Don't them down by crap LED fixtures!!!

Could also be the wrong lamp . Wouldn't be the 1st time I've seen 250w HPS fixtures with 400w lamps in them
