The Sunwayman L10A and L10R are flashlights, but at a 90 degree angle. Angle lights are great for attaching to your pack, shirt, or anywhere else that having an angle light would be more useful than a light shining up at your face or down at your feet. The interface is nice, giving you quick access to multiple outputs and strobe.

The L10A is the AA version and the L10R is the CR123 version. The L10R saves you a bit of size and has increased output over the L10A, making the more exotic batteries well worthwhile.
