I need a new bulb but than it would. All wiring and ballast look good

Why can't we just use led retrofit instead of replacing the whole fixture.

Sadly I don't have any of the mounting hardware I might try to make something that would do the same thing

Still a great find! Most that I have seen (and that is very very seldom) have the pole plates missing. They were galvanized steel. One smooth that fit in the cavity at the end of the fixture and one with a curved base and a graduated curve on the outside that fit against the fixture. The smooth inside plate was made to keep the aluminum from cracking when pressure was applied by tightening the bolt and lag screw. I have heard the word "Night Sentry" and LM might have called it that at one time but I don't recall that name used when there were produced.

Btw the grouves look rusty/dirty and that is due to the lighting

That is a Line Material "Dusk-to-Dawner" from the mid sixties. You are one lucky fella to get this since they are impossible to find and were not mass produced. LM had an option to the buyers of painting the fixtures in colors. Most were 175 watt mercury and came with a Tabet Manufacturing photo control which are also a rarity these days. I had two and one was mint green, the color of my dad's co-op's transformers and trucks. The springs that holds the internal reflector in place are impossible to find so don't lose or break one! These came with a "leveling plate" which used a 5/8" machine bolt and a 3" lag screw where a lineman could tighten or loosen the 5/8" bolt to the desired fixture angle height and then tighten the lag screw under it to lock the position in. I don't see that in your photo and if you have it don't throw it away, it is part of the fixture.

You are one lucky person to have found this!

The springs are rusty

WD-40 will stop the corrosion some. Be careful on stretching them though.

Are you talking about the outside of the fixture that is underneath the ballast?

Yes

I can't answer that, speculation the heat from the ballast over the years has faded the paint. If you want to redo your fixture to near like new condition, I suggest some good high heat aluminum spray paint. LM's color was almost a grey/silver original color. Some say it devalues the older fixtures and some say it doesn't. Its not like you are cleaning an 18th century rare coin. Do what you want to do with the fixture if you are going to keep it. I have redone some of mine and yet left others in good condition alone. I suggest do not use any kind of caustic cleaner on the fixture as they can as much harm as pouring acid on it. Warm soapy water can do wonders for the outside and the glass. If you do, leave the photo control on the light as you wash it in the installed position, never upside down. Just suggestions of what I have done,

These are cool, except for the 'socket'...I don't get the logic...it seems awfully flimsy.

Your mission - should you choose to except it - is to save unique and rare HID lighting before it's all scrapped.

The fixture not including the mounting part is about the size of a ael 25 glass

They are small but the heat from that lamp is the same.

I know LM offered it in 250w but I have never seen a "live" one. Those springs are the key to allow expansion without damage to the refractor. I saw one on ebay a couple of years ago and the seller had it mounted over his bed. I would hate to think the ballast was still inside and you wake up with a streetlight coming down on your head.

GE101R is correct, this is a Dusk-to-Dawner, NOT a Night Sentry. I don't believe that name was ever used.

Nice light! I think the only time I saw one in person was when I traveling through the US.
