How long will the Edison the Petit last when 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 after charging the lamp from the charger. Turning on the lamp while charging it the same time is not good for the battery, so the light will eventually get lazy and will no longer charge properly.
