If you are looking for a marker light that illuminates both upwards and downwards, then the "Orange" from Luxform is a great choice

This high-quality plastic lamp has 1 soft tone LED that shines downwards and 3 soft tone LEDs that shine upwards in a ring. All LEDs together have a light output of 10 Lumen.

The light is equipped with the AYR system.  The Intelligent operating system monitors the battery charge and controls the output lumen capacity evenly over 6 hours

This means that when the battery has received less charge the light will shine less brightly.

The big advantage with lights in this series is that you are guaranteed 6 hours of light every night
