I use the lamp for illuminating my workshop garage. For illumination at close range it more also is not enough, however. For use in the workshop, the light is too dim and diffuse. The lamp can be used at most as a backlight. Here is one of the three lamps for something more than 4 weeks the ghost. At first I thought it is up to the batteries. But with fully charged batteries and new batteries, the lamp is not lit after switching on three times. Too bad, the idea with the magnets I like that. Was exactly what I was looking for. Should keep only the lamp a little longer.
