Wiring Regulations Literary Question

Former Community Member

Hello all, I wonder if someone can help me please?

https://en.wikipedia.org/wiki/Voltage_optimisation#Overvoltage

I'm trying to get a reference for a section in this wikipedia article to put in a report I'm writing but I can't find the original source. Under the "Common Power Quality Problems > Overvoltage" section there is a sentence that describes "A 230 V rated lamp used at 240 will achieve only 55% of its rated life". From the article I believe it is from the book "Commentary on IET Wiring Regulations 17th Edition" from 2016, ISBN 1849197652.


I have tried to find it in a library as I don't have £90 to drop on a new copy of it, just to see if it is this book I should be referencing in my report, but I've had no luck there. Is there perhaps anyone with this book that knows whether or not the quote does indeed come from it or not?


Any assistance with this query would be greatly appreciated.

Thanks in advance

    Filament lamps are rapidly going the way of gas lighting and oil lamps, both of which are still used today for specialist purposes, but are no longer mainstream illuminants for homes or workplaces.


    Lighting of tropical animals, the rearing of young farm animals, infra red treatment of aches and pains, oven lighting and the like are present day applications.


    Back in the good old days, GLS lamps came in DOZENS of different voltages, most of them in a choice of pearl or clear, a range of wattages, and choice of B22 or E27 bases.


    This catered not only for the multiplicity of supply voltages, but also enabled to the better informed user to over or under run lamps when there was a good reason for this.


    These days most vendors only offer 110/120 volt, and 240 volt.
