I already used this kind of lamp for light therapy in the past (a "rondo" of INNASOL brand). In terms of efficiency, they are equivalent. Their light, very nice, really helps me to reduce the stroke of winter blues. They fulfill their function perfectly. However, at a practical level, this lamp from Philips is much higher. Being flat and relatively small, it takes up little space (flip side, it is difficult den benefit both, he fact that should be very close to the light source for which is to the effect). It does not heat up much. A kind of timer shows if lon spent enough time before the lamp for his daily light dose. And most importantly, more importantly, it is possible to adjust the intensity of light (which can hurt the eyes lorsquelle is 100%).
The major drawback of this lamp is the metal folding part that serves as a foot. The part that comes into contact with the support on which is placed the lamp is not covered and can leave scratches on wood furniture.
