In our tests, 6 lights lasted over 12 hours on one battery. By 12 hours they were noticeably dimmer. A test of the battery at 12 hours showed the voltage was down from 3.0 to 2.6 volts. The lights continued to stay on at a nice level for several additional hours before another battery was needed.
The coin cell holder is .24 inches thick and .9 inches across at the widest point. You can clip the plastic "wings" to save 0.1 inch on the width if space is at a premium!
