How long will the Transloetje last when I have charged it?

The Transloetje can remain in the first light mode for approx. 20 hours, at the second light mode for about 15 hours and at the third and brightest light, for about 9 hours.

Be sure to unplug the Transloetje 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.
