This Osram bulb is now exactly in you right direction:
- Priced okay, after about 2500h of the purchase price is in it again. (At 20cent / kWh)
- A light with a very pleasant color
- Completely silent, immediate full brightness
- The housing is made of plastic and is not very hot, which suggests a very efficient interior.
- The light is bundled in 25 ° angle, so unlike CFL lamps can thus illuminate something.
I think soon we can recommend unreservedly LEDs - worth doing now already, the cheaper they still are the more money you save even.
