Wiring Regulations Literary Question

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

  • Agree, non-filament lamps do not obey any such rule, and the thing that really affects the life of  LEDs is temperature, and the thing that kills switch mode supplies is spiky mains and rapid drop outs and restarts, rather than modest fluctuations. Certainly if the phrase remains it needs a note that it really applies to tungsten filament lamps rather than anything else.  Certainly any argument that a voltage optimiser saves you light bulbs is less solid than it was.


    I think 'moved on from' is a bit strong, I'd prefer 'moving on'  but I agree that new buildings are not being fitted with filament lamps and that trend is set to continue. It's a shame that the LED 'bulb replacements ' are very much designed to run hot and fail early, and therefore put electronics into landfill,  but it is an obvious commercial strategy to retain volume sales.
