Electralube Light Bulb Lubricant — Prevents Shattering


From a Cool Tools review:



Electralube Light Bulb Lubricant

Lubricates light bulb screws to protect against corrosion, moisture, and broken light bulbs

Nowhere on Earth is the concept of entropy more apparent than aboard an oceangoing ship, which is where I first discovered Electralube.

As a third assistant engineer, one of my unglamorous regular (and never-ending) duties was "re-lamping" — replacing burned-out light bulbs in all the ship's machinery spaces.

The combination of 24/7 use, moist salt air, and vibration caused the flimsy metal threads of the bulb bases (don't even get me started on the idiotic design that is the Edison screw!) to rust or arc weld themselves into their sockets, which meant a broken bulb and additional sweaty minutes atop a ladder on a pitching ship with a pair of needle-nose pliers and a headlamp, trying to pry the stuck metal bits out.

Electralube put an end to all that.

It's a light, conductive grease that comes in a little jar with a sponge in it.

The sponge holds the lube.

You just dip the bulb base in the sponge, give it a spin to coat the threads, then screw the bulb into the socket.

I use it for every bulb change and it's essential for fixtures in damp locations, and for that corroded, janky old socket you've been meaning to replace in that beloved antique lamp.

The next person to change that bulb will thank you.


From Amazon:


Electralube Solves Broken CFL Bulb Nightmare

"Curly" compact fluorescent light bulbs (CFLs) contain mercury and are a serious hazard to clean up when broken.

Electralube prevents corrosion to light bulb threads and light sockets so they no longer lock up.

Maintains long-term conductivity in your electrical connections.

Installation and removal of old bulbs becomes a breeze with no more glass separation from the base.

Super helpful when working on ladders or in crawl spaces — electrical plugs ease into and out of plug receptacles.

Features and Details:

• Non-flammable non-toxic food grade specially-formulated mineral oil rendered during a specialized distilling process, creating the perfect consistency to lubricate electrical connections

• Flip-top lid is attached to the container so you won't drop or lose it

• Perfect for storage and travel as lid creates a secure air-tight fit

• Each container lubricates approximately 200 bulbs

• Container fits in the palm of your hand


$14.95 (light bulb not included).

Too expensive?

What's your out-of-pocket cost at the ER for an x-ray + stitches after you've sustained a deep palm laceration from a light bulb shattering in your palm?

Or required reconstructive surgery of severed tendons?

Not to mention the subsequent pain, disability, and time spent treating same.

Wait a sec... what's that 1973 movie I'm remembering, it was soooo good....



Note: I featured this product back in 2016 and again in 2018: who knows how many serious lacerations and tendon injuries were averted by those who bought it as a result.

Perfect gift for the person who thinks they've got everything.

I live in the high desert of Utah. I use a different product (unfortunately, it's $25, but it's also last 10+ years) to deal with our fine sand (it might be a little alkali too). Light bulb bases get bonded to their sockets here too.

You made the statement, “It's a light, conductive grease that comes in a little jar with a sponge in it.”
I’ve combed Amazon, the manufacturer’s site, and several sites that talk about it, and can not confirm it is conductive. They claim using it on cars and outdoor applications but for that you want a dielectric grease. Water in contact with a conductive grease provide a path for those little electrickys to sneak out after curfew which is shocking. It doesn’t take much of a leak to raise hell with modern electronics, especially when they carry power and signal on the same wire.
