How many engineers does it take to change a lightbulb?
One, but they’ll spend three hours checking it for alignment and leaks.


There are thousands of jokes on this theme but anywhere, factories, offices, warehouses, supermarkets, sports stadiums, railway stations, ocean liners, road lighting and other applications where thousands of light fittings are installed it can be a major maintenance expense rather than a joke.

SuperCorr A is a corrosion preventative dry lubricant aerosol which rejects water and protects the bulb socket and fitting and prevents sticking. This makes bulb changing easy and quick. Have a look at the website to see how one chemical manufacturer saved thousands every year by using a SuperCorr A aerosol. Click here

Competition  – Here is another  light bulb joke  to put you in the mood.

How many mystery writers does it take to change a light bulb?
Two. One to screw the bulb almost all the way in, and one to give a surprising twist at the end.

Send us the best light bulb joke you know (printable) and potential applications you have for SuperCorr A . The winner, judged by me, will receive SuperCorr aerosols and a mystery prize.

May the best joke win
