Actually, battery life is one of the things current customers really like. They also appreciate the fact that the LED system dosen't generate heat on the music stand. Evidently the competing lights orchestras, choruses and the like use have far less capacity. Keep in mind, these lights aren't intended for folks like us who play 4-5 times a week. Most of us don't use music stand lights at all (at least I don't).Again, I'm not trying to sell individual units to anyone, I'm looking for representation.
Thanks,
