Therefore I probably sometimes use terms that are not correct in a given context. I say this because I'm not sure whether "research" is the right word for what I'm=20 doing when I try to get informations about specific products. Maybe the=20 word "investigations" is better. :-) But to answer your question. I think that LED lighting will be the main=20 "Light technology" for the next years or even decade(s). But there are maybe good chances that the classical semiconductor based LEDs will be=20 replaced or at least supplemented by OLEDs or a similar technology. In the last months I replaced nearly all conventional and "energy saving" light bulbs in our house. I use LEDs with 4500K in the baths, floors and=20 in the kitchen, 6500K LEDs in my office, 3200K LEDs in the bedrooms and 4500K as well as 3200K LEDs in the livingroom. I really prefer LEDs over conventional energy saving lamps, because they have a much higher lifetime and IMHO also a better light spectrum.=20 Of course there are high quality full-spectrum energy saving lamps and I used these before in my office but they are expensive and they have a much shorter lifetime then LEDs.=20 -- Regards wabe
