Here’s another unit you’ll want to get used to over the next few years: the lumen. If you’re not familiar with it, it’s (roughly) a measure of brightness. A traditional pearl 60W bulb gives out about 700 lumens.
And this is important, because you’re not going to be able to buy a traditional pearl 60W bulb in Europe for much longer – that’s the theory anyway, though a loophole may help out – and it turns out that manufacturers of low-energy replacements have been misleading us somewhat as to how bright they are, claiming that bulbs are ’60W equivalent’, for example, when in fact they’re quite a bit dimmer.
So, look at the lumens, not the watts, because the watts, they are a-changin’.
And I’d better start stockpiling incandescent bulbs until someone produces a low-energy one that works with the dimmer switches that are throughout my house. Thankfully, they’re not far away…
