The v900L is the newest iteration of the Syris light, and is a major advance in usability and convenience. It incorporates an LED light source and thus draws less power than standard halogen bulbs, enabling new and significantly more efficient batteries to power the v900L for an entire day without re-charging, even in my purely-laser practice.

This is a major convenience, especially when performing laser surgery with the surrounding tethered foot pedals, power cords, and actual laser devices, which may become tangled with a headlamp that is connected to a transformer and plugged into an outlet. Future studies should focus on expanded use of the Syris v900L for increasing diagnostic accuracy when evaluating pigmented lesions or
