Low energy lamps
What's the normal failure mode for low energy lamps? I have (had!) an
Osram Dulux 20W/827 lamp just above me and all of a sudden it failed - no flickering, no dimming - it just went out! It's temporarily replaced with a 40W candle bulb which was lying about downstairs until tomorrow. -- Frank Erskine |

I hope it is not a bad batch as the delay is long enough to be tiresome. I must try one of the others sometime. I do not have any low energy bulbs in locations where I really need immediate light, so it may be that I have simply not noticed. But I have had earlier compact fluorescents which were tediously slow in comparison (not to say dismal in light output), so I was a little surprised at your experience. It's only a shame that the areas of the house with the greatest lighting demand have fittings which will only accept more standard bulbs.

You can cover the pacemaker extraction site with a shroud. I think some might be upset if undertakers started whipping out teeth. Dentistry on the corpses that need it would be cheaper, even in the long run, than filtering mercury out of incinerator smoke. With mercury amalgam being phased out albeit slowly and people increasing outliving their teeth it might even be a problem that will go away shortly without any active intervention if the current proposals of halving the mercury output are not changed. -- Roger Chapman |

But I have had earlier compact fluorescents which were tediously slow in comparison (not to say dismal in light output), so I was a little surprised at your experience. Some of my earlier ones definitely took several seconds (or possibly even longer) to achieve full brightness but this Morrisons one is unique in my experience in that it doesn't show the slightest glimmer for at least 2 seconds. It must be a bad 'un. I picked up a handful yesterday and tested each one - all lit with no delay and the amount of brightening after a couple of minutes was quite small.

It does if the bulb protrudes in a non-pleasing fashion. In fact, it's worse if there is a shade in that respect. Thanks for the links.
