Apart from two light fittings, all of the bulbs in our house are traditional incandescents. And there are lots of them. Tackling them all at once would be a mammoth task, so we’re going at it in a piecemeal fashion. Now that the evenings are drawing in we’re using the lights in the house a lot more, and I think they’re starting to become a significant drain on our electricity consumption.

My first spot to start was the bathroom. This has three – yes three – recessed light fittings. That makes it sound palatial, but it’s not. What it is is unbearably bright. Each fitting takes a full-size “R80” 100 watt reflector bulb. Luckily these had been progressively blowing, so at point of replacement we only had one running, and the light in the room was adequate, although poorly spread.

After some detailed online research I gave up and went to B&Q. Quite a lot of money later I had three Megaman 11W R63 reflector bulbs – each one equivalent to a 60W conventional bulb. I went for the slightly smaller, lower-powered R63 size because I new that three 100W-equivalent bulbs would be far too bright.

Putting them in was easy; the bulbs fitted perfectly and didn’t protrude from the ceiling. Turning them on was a little less impressive. Startup is a little slow, with them remaining dim for a little too long for my liking. Once they are all going though they are impressively bright – in fact if they’d had more of a choice I might have been tempted to go for something closer to 8W (40W equivalent). Still, even with these three, we’ve reduced the wattage in the bathroom from 300W to 33W – that should help our electricity bills a little, be a good step towards our 10:10 target, and make us a little more solar-ready.
