GREASE those threads…
We are replacing 75 outdoor area lights and would like to lube the threads on the medium base lamps so they do not corrode in the socket in the weather.
I believe there is a grease made for this application. Which is _______?
Or, can I use a dab of Never Seize?
(We would like to use commercial PL 13 fixtures, but when the board saw $300/head cost, that idea when down in flames. The same thing in medium base, 60W incandescent was $100.)

WD 40
Plane old Vaseline will work (it's what's in many types of contact grease). But silicone stuff is probably a hair better. Buy something like "Type Z5 Silicone Compound" (GC brand) at an auto parts place. They'll likely call it "high voltage grease" or some such.
DON'T use "conductive" grease (or CU/AL compound), unless you're VERY careful how you apply it. The grease does not need to be conductive.
White Lithium, if you use wd-40, you will be "wantin death @ 40 yrs old"..it is NOT what ya need. So many folks believe in the properties of WD it is not funny..it has it's place, but this ain't it.

Apparently I am the possessor of bad advice which I then passed out.
My Apologies (and I now hope he didn't follow it!).
I got the advice from an electrician yrs ago. Can you explain why it doesn't work. I ain't arguing, just want to know the why.
i'll take a stab at one of the reasons. wd is mainly a solvent,that will work into tight areas to free something up. but after a short while [ a day a week?] it's lubrication properties are gone. just spray a little wd forty on a pc of metal and beside it put a dab of grease,leave it for a week and see what you think. now if you had a light bulb stuck in a fixture,i think it would be great to help get some lub up into the threads and loosen it up. now you got more advice to pass on! larryhand me the chainsaw, i need to trim the casing just a hair.
Partially because WD-40 offers NO long term lubricity, it quells the friction for about as long as it takes to evap. Which is it's call to glory at times dispelling moisture , quickly. But any dessicant ( ability to absorb, vs, displace) h20 can be a better choice.
Wd-40 is repellant and a slight dessicant by using alcohol as a vehicle, masked under the guise of a lubricant ( which would by the definition, need more than 2 mols of H) a surfactant would employ 3. Ionization of "O" begins with the first available hydrocarbon witha mol heavier than it self, hydrogen is next in slipperey, when in cojunction w/ ox...
This is why we can't ( yet make) Ho4 as a fuel, but it can be done under vacuume and very scary controlled kelvin temps..cold fusion is in my back yard, so it is in yours..
Oh, you wanted to know about wd-40...it burns. It also has no long term hydro carbons that don't oxidize quickly, thats why you keep buying it, over and over again, it don't have the life of lithium nor graphite, just the hype..ask NASA.

Well, WD-40 contains relatively little actual lubricant -- it's mostly solvent -- and both the lubricant and solvent are petroleum products, which it's best to avoid around plastic.

i heard the heart of wd-40 is fish oil. dont know tho. can does say petroleum on it.

Dielectric grease. Same thing you use on automobile bulbs and connections. Get it at an auto parts store.
is that not the same thing that you goob up on the battery teminal connections to keep out the air and thus prevent corrosion?
one guy was crazy for Kopr-Shield ¯ from Thomas & Betts,
another sparks liked Molybdenum Disulfide, but had to wait for it to dry,
another guy had found some graphite powder and mixed it with a dab of oil......
I use a carpenters pencil

"another guy had found some graphite powder and mixed it with a dab of oil......I use a carpenters pencil"You are deliberately introducing graphite - ie: carbon, a conductive material - into a light socket?BruceT
been using a pencil to lube the threads for about 35 years ....never coated the entire base with the stuff.why ?years ago, I think it was GE that sprayed a dot of something on their mogul based discharge lamps

With whatever grease is used, it's generally only necessary to use a small dab. On regular bulbs I put a tiny dab on the center contact and another slightly larger dab (matchhead sized) on the threads, near the end closest to the center contact. The stuff is spread around as you screw it in.

I just run the pencil across the threads several times , twist the lamp into the socket a few times, and then button'er up.

Never sieze may be conductive, which sounds like a bad Idea, but in reality probably has no real effect. On the other hand, it's messy. I'd use bulb grease by AGA (american grease stick), or permatex dielectric lube.
Did you know a black carpenters keel is almost pure graphite ina wax base? I stabbed a hot wire in one end and a ground in the other once just to see what happens..try it some time, wear goggles and running shoes...BOOM!
It went off like detcord, scared the begeezus outta me.
Oh wait..mebbe it was carbon rod back then..I think they altered the matrix since..lemme go see.

Lemme know how that works out for you.
I just did..nada. Why do Ihave bare wires just hanging out waiting for me to play with them?
I flipped the breaker and it fizzeled the keel into a hot wax melt, then the breaker popped. Not what I expected at all..damm, I was all gussied up with googles and shid...what a let down.
shucks, I wanted a serious boom.

I really shouldnt tell you this. I have heard tha if you take Ivory soap bars, make them into powder and dry them, they become explosive. Never tried that. Maybe add a little diesel fuel.
Some of my stories are somewhat unbelievable, but they are true. Granny lived at the foot of Pine Mountain in Letcher County Kentucky. There is a rock quarry, and possibly some working coal mines left on the mountain at the time. Well, anyway, a flash flood comes and nearly washes her house away, did take out the old outhouse and smokehouse that had been there for MANY years. Also wiped out the clothes line. But granny spied a pretty new coil of (you got it, detcord) laying in a pile of debris. So she strung it up and hung out the clothes. (She never owned a clothes dryer). Someone pointed it out, so it was removed and somehow later detonated with a rather impressed Granny watching the show.
LOL..I was NAS after HS, a buddy went to FT Hood ( ranger type) Army...we had a party, volley ball and beer..LOTS of beer..well at 2 am it got pretty dark...so Ranger ( the names have been changed to protect the infractors) sends up a Parachute flare...awesome to the extreme, we can now see the ball field..
I lived in Mil houseing, had a freaky neighbor, who threatend to call te law..Then Ranger takes flight on his Harley..went a few miles away and POOF! a red flare....Cops come to my place , you know the drill..drooling mad neighbor, beer kegs flaoting in Ice water, 36 drunk airmen and wives..a volly ball still somehow in the air..and the weed stink.
Poof! another flare..waaaaaaayyyyy over there..Barney Fife and sons get in the cruiser....POOF! another flare waaaaaayyyy over THERE...these guys went nuts on the CB trying to find a Freaking Army Ranger, with a back pack full of flares..over two counties..
LOL , Ranger comes back dead stick on the Harley so as to be quiet..like. and Arms off a white parachute..let the games begin, again..and the whole scene was REAPEATED again.
We did finish the game of a win over the brats..21/17..4 half kegs later. And a few got away.

Ah, the good ole days.
I actually own a military house. 1945 prefab cape with real 2x4 etc. Strange construction though. It was off base officer housing during WWII. My street is named Bataan after the Bataan death march.
yer scaring me now

I think it really was named for the battle of Bataan, although some houses on this street were completed in 1943.
Rust belt, WWII, its all the same at that point...one war machine after another...and another.
This ain't a military op, that supplies work force, this is a conundrum of pollution that we as a country spew about the planet..good news is, there aint none.

I use (have a tube sitting in front of me) a tube of DIELECTRIC CONNECTOR GREASE>
+ Prevents corrosion
+Eases Disassembly
+Resists Arcing
+Waterproofs
Its made by 'VersaChem", part # 15339, and says "100% silicone". About the size of a med tube of toothpaste.
Pretty sure I got it at a car parts store since the instructions specify how to lube // spread on spark plugs and spark plug boots / ignition coils etc to insure good connections.
I use it on auto bulbls etc to waterproof, can lights in my kitchen (cause they get hot and hard to remove) and bulbs in my garage which also get hot and hard to remove after they burn out in a couple years.... you know the symptom..... hard, scratchy, resist turning out? This works great....

Yes, followed by some work with a needle nose on a broken lamp. Breaker off, of course. Me on ladder on soft dirt. Teeter. Teeter.
OK, I will eschew the Never Seize in this application and get the purpose-built stuff.
(Another great substance, but not for this, is anyhdrous lanolin. Can still open the shackle key on my anchor after 30 yrs in service. But never try it on your thru-hull valves. Stiffens up in cold water. Never seize on the shaft/prop.)

Well, too heavy a coat could produce a short over time, or more like a "trail" that current would follow and overheat the fixture. A light coat that's kept only on the contacts would be OK, if you were confident that it wouldn't "run".

Thanks.It is pretty common for me to see it gobbed on at the main breaker (often at the top[ of the box, with the anti-ox above the breaker.)Obviously, we're not talking about the sort of heat issues there would be with a lamp, but is it wrong to gob it on like that?

It's a question of the specific composition of the grease, plus the distance between conductors (across an insulating surface). If the grease is at all conductive and is layed across a conductive surface from one conductor to another (or to ground), sooner or later the particles in the grease (if there's enough of it) will tend to "align" themselves and produce a conductive trace pronounced enough to produce heat. It can snowball from there.

Interesting.; I'll have to start watching for that.

TB,
I've used this for same application you talking about...plus its intended use (auto electrical...great for trailer wiring/lighting)
http://grote.com/cgi-bin/goc/goc.cgi?product_number=99170
BTW, PL 13 vs incand.... I have lots of these in service.... I would go 26w quad if possible on compact fluorescent for ground lighting.
I have one set (200+ P.O.S. fixtures) of PL13/ PL9 exterior converted from incand. in mid 90's, now being redone again - complete junk.... costing them more to replace than they saved in 10 yrs of electricity "savings"
