Do you still have any of these in your house?
MrsB assures me that these old-style filament lightbulbs are very rare in Hong Kong nowadays, and that everyone knows about the benefits of compact fluorescent (CF) bulbs. But I see that Wellcome and Park n Shop still give shelf space to the old-style bulbs, so someone must be buying them. If you know that someone, how about persuading them to make a belated new year's resolution, and switch to CF this year?
The new CF bulbs are slightly more expensive to buy, but more than pay for themselves with the savings they give you:
You get to do your bit for the environment too, as using less electricity means causing less pollution, and less lightbulbs mean less landfill.
If you represent Wellcome or Park n Shop, how about a resolution to stop selling the old-style bulbs in your stores this year? It'll have minimal effects on your sales, help the environment, and bring you some positive PR all at the same time.
