Lightforce XLi Therapy Laser

Capable of delivering up to 40W of power, the LightForce® XLi is the most powerful device in the range.

Capable of delivering up to 40W of power, the LightForce® XLi is the most powerful device in the range. Its increased power reduces the time needed to apply a therapeutic dose of light energy, and with real-time dosing feedback and the XL Treatment Cone, deeper structures can be treated faster over larger areas, all of which helps clinicians to increase the efficiency of their practice.

LightForce® Therapy Lasers are the industry leader in medical therapy laser manufacturing. For more information on the LightForce® Therapy range, click here for an Introduction to LightForce Therapy Lasers.

LightForce® XLi Therapy Laser

Treat larger, deeper structures and provide faster pain relief with real time dosing feedback.

Ideal for: The busiest practices treating the most challenging cases.

Faster Treatments.
Deeper Structures.
Larger Areas.

The new 40W LightForce® XLi with Empower IQ™ Delivery System combines power and intelligence to bring innovation to the laser therapy treatment room. Designed for busiest practices who desire the fastest, most effective treatment solution, the LightForce® XLi brings science and technology together to treat deeper structures more efficiently, making it easier to impact pain.


The 40W LightForce® XLi 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.

influence® Technology

influence® Technology harnesses software and hardware advancements to enhance treatment applications.

Customized Take into account patient-specific considerations to deliver the most appropriate treatments. Customize your treatments based on condition, skin type, body type, and acuity.

Consistent Deliver the same effective treatment every time. Easily save and repeat treatments with confidence.

On-Contact Treat like no other therapy laser can with patented contact-application technology. Benefits of on-contact laser therapy treatments:

  1. Compression, reach targeted tissue by removing superficial absorbers
  2. Collimation, tighter beam minimizes energy loss
  3. Reflection, significantly reduced in contact mode
  4. Soft Tissue, manually work tissue while delivering energy
  5. Refractive Index, minimize light loss due to similar index of skin and lens composition
