The elderly couple whose house I look after have recently reported that
three light bulbs have "exploded" when turned on, and dropped the 6A
circuit mcb each time.
They didn't mean that glass was everywhere, but they obviously went with
a real bang. This is a 5-branch ceiling fitting, with 40W clear
golf-ball incandescent lamps in close-fitting open ended glass shades,
cap up at about 45 degrees. The problem has only started since I
started using Supalite branded bulbs instead of Tesco branded ones.
Here's the latest failed lamp, with a hole blown in the cap:
I'm concerned because of possible damage to the fitting, and because one
of the elderly couple will stumble around in the dark sooner than reset
the trip or ask for immediate help. I really, really don't want to go
through choosing a new fitting with them, so what should I do?
Carry on and work through the remaining stock of 10 Supalite bulbs, in
the hope that the rest will die more quietly?
Throw the Supalites away (the ebay seller is now NARU, though several
other sellers still sell this brand) and buy a better brand? If so,
Report these lamps to Trading Standards as potentially dangerous?
Find an alternative technology lamp that will replace 45mm globe lamps?
Which? The overall room light level must not drop - they both have
incipient cataracts and other visual problems.
