I use the clip light for a 27 liter breeding tank and am very happy with it. Have I first wondered how regards the lamp, no switch is off, until I came by chance to the base - touch switch :-) the quality of light is appealing for low power, particularly in the 1st stage; the 2nd stage seemed a bit cooler by the switched-blue LEDs, but the 3d level (only blue LEDs) is sufficiently bright for twilight / moonlight. The flexible lamp arm remains well in the set position - no problem. Would I buy it again.
Addendum 06.04.2015:
now LEDs are always times in a row failed, went off with a series of blue, now only light up almost half of all LEDs .... will probably be due to the electronics, because LEDs should not go wrong really, I would not get again.
