I've bought the table lamp, because I prefer a pleasant light on my private work. The table lamp is delivered namely with a bulb that produces a cold white light (see Item: G23 energy saving lamp 11W white). This may be good for the office, but less suitable for this cozy home. So I an illuminant with eye-friendly things, warm white light to be ordered (see article: G23 energy saving lamp 11W warm white). The light color is reminiscent of earlier incandescent and is perceived, for example, while reading a book to be very pleasant.
