Purchased as a music stand lighting. As for illuminance also for music notation I feel exactly good. Because there are 10 grains and many grains, the shadows of each LED come out and it is hard to see? Although I thought, it will illuminate uniformly properly. Actually, one week ago I bought a similar thing at another famous net shop, but returned it with no lighting. Although both are made in China, this manufacturer seems to be manufacturing control by Japanese manufacturers and is highly reliable. 6 months' compensation is also attached.
