How long will the Edison the Petit last after I have charged it?

The Edison the Petit can remain, after it has been charged, in the first light mode for approx. 24 hours, at the second light mode for about 15 hours and at the third and brightest light, for about 6 hours.

Be sure to unplug the Edison the Petit from the charger after charging the lamp. Turning on the lamp while charging it, is not good for the battery, so the light will eventually get lazy and will no longer charge properly.
