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, which brand?
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.
