The new 40W LightForce XLi with Empower IQ Delivery System is our most powerful laser ever. The increased power directly impacts the time needed to apply a therapeutic dose of light energy, allowing clinicians to decrease the time required to treat effectively. The higher power equips clinicians to treat deeper and faster while covering more tissue area with the new XL Treatment Cone. The Empower IQ Delivery System provides on screen and in hand recommendations to increase the accuracy of treatments. Off and on-contact XL heads allow users to treat large surface areas quickly without jeopardizing patient comfort at higher power settings. In order to achieve effective treatments and improve dosing accuracy, the XLi assesses the operator's speed and gives real-time visual and sensory feedback. The in-depth protocol settings provide recommended parameters on treatment heads and power levels to aid in technician confidence and reduced learning time.
