I did eye ball it and yes as many TV shows not very well done to put it mildly. As to transforming the voltage I have never smashed open a GU10 lamp so don't know if simple element or not so will not comment on that.
But with a GU10 there is a glass envelope over the quartz envelope so no way can one put your fingers on the quartz.
I watched a repeat the other day of one of the builders from hell things and it was saying how to do the work the guy needed to be Part P registered which is now not correct but was at the time it was made and really these shows are just not good enough to ever repeat.
