In the living room we have this beautiful ceiling lamp, which creates interesting shadows. It's dimmable so it's easy to set the right level of lighting, and dimming also saves energy. These days it's possible to get dimmable LED lamps. It's a shame they are quite expensive but on the other hand LED lamps last very long.
Candles are a perfect way to create warm and cosy lighting. I've just been buying regular candles from the super market, but now that I think of it, the ingredients in regular candles are not so nature friendly or at least not so animal friendly. That's why I'm going to buy soy candles next time I'm going candle shopping. I'm not sure if it's possible to buy them in the super market, but I'll find out.
