Thats right Trumpy. I've gashed my thumb badly on a cheap no-name imported bulb when it cracked when I was putting it in. I was quite surprised how thin the glass was. I'm used to our bulbs being quite robust here, not egg-shell thin, and normally you'd have to squeeze mighty hard to break it in your hand.
At your advice Trumpy I'm going to stop changing light bulbs with the switch on. I've just imagined having a cheap bulb smash in my hand at the top of a high ladder, and as I plummet to a broken neck, wondering which hurt more; the 240 Volt shock or the laceration to my hand ?
I can't find any requirements in the standards for bulb glass thickness. Can anyone else help here ? It seems that bulb glass only needs to be thick enough to withstand its operating temperature. No mechanical strength requirements whatsoever.
