It's quite interesting why nobody's talking about making the light bulbs properly. For example the world's oldest still burning lightbulb in Livermore [1], which represents the technology when the bulbs were made to last.
Here in north the energy efficiency is bit different than in south. The heat the lights generate warm up the house and you cannot calculate the waste as you would in the warmer parts of the continent.

- starwed 15y agoReading the bulb's wikipedia article, sounds like it is not really the bulb's technology that's responsible -- it is very low power (4 watts!), and has a dedicated steady power source. (I previously lived in an apartment with erratic power, and incandescent bulbs only lasted a couple weeks until I got the landlord to fix it.) If you asked engineers today to come up with a long lasting 4 watt bulb, they'd probably do just fine.
- pimeys 15y agoThe site reminded me from a TV documentary which stated that there was a light bulb cartel which enforced the manufacturers to build bulbs that lasted only about 1000-2000 hours to get more sales. I'd like to link to the video, but I saw it from finnish national television. Edit: Oh yes it was linked on that site. http://www.catalanfilmsdb.cat/en/productions/documentary-television/the-light-bulb-conspiracy-ndash-the-untold-story-of-planned-obsolescence/2749/ http://www.catalanfilmsdb.cat/en/productions/documentary-tel...
