All in all a very good product, too bad it only works on batteries and there is no possibility to connect an adapter or external rechargeable battery. It light up well, I use it in conjunction with the K&M 12256 Desk Foot FlexLight which has a magnet and allows me to stick the lamp on the side of my mixer and illuminate al the knobs of the mixer and effect pedals on the floor at the same time. The only thing bothering me is that I like to use a more warmer light and these have very cool white leds.
