An Experiment after Christmas
The days between Christmas and December 31 are always a quiet period. During this period daylight is short, the weather is unpleasant (at least in the Netherlands) and the whole world seems to be asleep. It was time to do an experiment in the home in which we lived as of 1977. The experiment was to count the number of lighting fixtures in place and check lighting needs in 20 years time and combine these with the actual usage pattern. It was a traditional eco-investigation: do needs and functionality (still) match in view of developments in technology, in this case the availability of a wider range of energy saving lamps. The outcome was a surprise in two ways: ?There are many more lighting fixtures in your home than you think there are ?The hours of use warrant a much more extended use of energy saving lamps in spite of their higher price. Altogether, there were many good reasons to plan for lots of replacements in the new year. When checking for the lamps I got seriously disappointed: ?The choice of energy saving bulbs with low wattage (having the lumen equivalent of the incandescent bulbs to be replaced) was very limited. ?The color rendition of most of the energy saving bulbs was poor. Energy had been minimized but a little efficiency sacrifice in order to bring color rendition up to the level needed for living rooms had not been considered as yet. ?Some of the bulbs were too big to fit inside the lamp shades. ?Energy saving bulbs with small fittings were not available.
