Dual Functionality
 
When used as fixed lighting, which could be on a bedside table, between books on a shelf or on an office desk, the dual functionality allows direct connection to a power supply with a USB cable, and even if the batteries are not inserted, the lamp will work perfectly.
 
If used as a moveable lamp, SOWDEN supplies two 18650 2600mAh Li-ion rechargeable batteries making the lamp convenient in places where electrical connections are not easily available - this gives the possibility to take light safely anywhere indoors or outdoors.
 
The PL4 has three dimmer settings, controlled by tapping the top of the Sowden LightDisc. The shade is removable for easy cleaning. It charges via USB (cable included) for four hours of light at maximum brightness when fully charged.
