Title: Music Lights
Review: I ordered a dozen of these lights for our school chorus and chime choir for an outdoor evening performance. These lights worked really well, clipped onto our music books easily, stayed in place, and cast adequate light. The packaging says the batteries should last 10 hours, but we probably won't reach 10 hours of use for a few years yet! A great purchase.
