Ambient illumination

Long ago I began thinking about how we could illuminate our rooms when they're finished.

Of course, since I'm a science geek and care about environment, I immediately thought of lighting up using LEDs.

My only problems on my way to ultimate enlightenment were the still low light yield and the high price of LEDs at that time.

Recently these thoughts bubbled up in my mind again and I again began to investigate the possibilities of LED-illumination in my home.

It seems, that the output of LEDs has increased in the meantime so that regular light could be replaced easily. But the price for this hasn't lowered that much and I'm unsure if the energy-savings compensate for the initial investigation.

Well, the only source for LEDs around here, although Germany isn't quite "here" but at least it's in Europe, I found is They even have lightbulb-replacements but I'm not willing to pay up to 60\x80 for a single LED-bulb. And that's just the price if I order 100 pieces at once. Well, they have smaller ones starting at ~10\x80 for white ones but that's still a bit high.

I would also take the adventure and buy a bulk of raw LEDs and some metal and solder together my own stylish lamp, I'm just missing some ingredients right now:

  • cheap source of high-output LEDs
  • description how to create a power- and control-circuit for the LEDs

If anyone can help me with one of those, please leave a comment and point me in the right direction.
