Light bulbs


Carried out a light-bulb audit. This revealed that I had low energy bulbs fitted in only 7 ceiling pendant lights, leaving a total of 33 light-fittings with tungsten or halogen lamps that in theory ought to be replaced. The only other lights I could leave unchanged were the two worktop fluorescent strips in the kitchen (although each uses 75W), and one in an understairs cupboard. Not that easy to find SES fittings giving the right brightness for reading, or fittings for spots of ceiling downlighters that did not take 20 minutes to warm up, or fittings for dimmable lamps, but Asda and Homebase were selling the standard Philips Genie sticks and GE Spots for a good price and I sourced the more difficult ones on the web from Eco-Friendly Lightbulbs and Efficient Light, both of whom were good enough to take back lamps that did not perform as intended (usually related to taking too long to warm up, or not being compatible with dimmers). To date I have replaced 22 bulbs, at a total cost of £59.73, achieving a reduction in power usage from 1300W to 294W.
