So what kind of light bulbs do you buy these days?
Do you hunt out the traditional tungsten filament bulbs? Are you happy with those first generation energy saver bulbs that are mini flourescent tubes? Or have you been impressed with the bright halogens, or even the expensive LED ones? And what is going to be invented next? And when will there be a sentence in this blog that doesn’t finish with a question mark?
They all use different processes to emit light, and the level of energy saving is really about how little heat they can be persuaded to give out as they do so.
And how much you like them depends on how comfortable you are with their version of white light. How you see things does depend on the quality of light you are getting. People who suffer from SAD (Seasonal Affective Disorder) use special light bulbs in the winter that produce light that has a recipe that is the same as the summer daylight they are missing so badly. Some buildings (can’t remember where now) were declared unhealthy because people had to spend all day in artificial light.
We respond to natural sunlight best.
We also respond to natural Son-light best.
We can’t live without either of them. Literally. In both cases.
