LightForce® Therapy Lasers are manufactured in the United States and are rigorously tested for safety and consistency.

Over 250 professional and college sports teams trust LightForce® Therapy Lasers for their athletes. LightForce® lasers can be seen on the sidelines of the EFL Championship, Premier League, Olympics, NFL, NBA, MLB, NHL, MLS, PGA Tour, Cirque Du Soleil, UFC, and the X Games.

With over 7,000 articles published on Low Level Laser Therapy, photobiomodulation is well established in the scientific community for efficacy in treating musculoskeletal pain and increasing local blood circulation.

FXi 15W

Treat quickly and consistently on the go. The 15W LightForce® FXi is ideal for those practices or athletic training rooms needing to treat in multiple locations in or out of the office. Easily transportable with an integral battery, the lightweight FXi quickly impacts pain while weighing in at only 7 lbs.”


Influence® Technology takes into account the patient’s unique absorption characteristics and specific clinical condition to help provide the most effective treatment. Patient specifications such as condition, body type, and skin type are taken into account. The in-depth protocol settings provide recommended parameters on treatment heads and power levels to aid in clinician confidence and reduced learning time.


Models: 40W XLi, 25W XPi 

The LightForce® Empower IQ™ Delivery System is changing the game in laser therapy emission. Designed to be user friendly and responsive, Empower IQ™ is the new generation of delivery technology.


Ultra-premium workmanship and next level durability. Extra-long for user convenience.

Smart Handpiece 

Built-in dosing feedback technology with embedded finger switch and indicator lights. In order to achieve effective treatments and improve dosing accuracy, the Smart Handpiece assesses the operator’s speed and gives real-time visual and sensory feedback. The Smart Handpiece is ergonomically styled for operator comfort.

Quick Disconnect Heads

Quick release and change-out treatment heads for better ease of use and versatile delivery options. The smart system senses appropriate applicators, treatment heads, associated power, and treatment hand speed.


The exclusive LightForce® patented massage ball allows the clinician to treat patients on-contact. 


The on-contact massage ball compresses superficial tissues, displacing excess fluid and helping to enhance laser penetration to deep structures. This compression reduces the impact of superficial absorbers. 


The massage ball acts to collimate the light beam, helping to reduce energy loss. 

Refractive Index 

The fused silica composition of the massage ball helps minimize light loss as it passes from the massage ball into the skin. 


On-contact application of delivery to tissue minimizes energy loss due to reflection. 

Soft Tissue Work 

The massage ball allows the clinician to do manual soft tissue work with the applicator while delivering energy.


Ranging from 15 all the way to 40 watts of power, LightForce® Therapy Lasers provide the power needed to reach deep tissues. 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 in less time.


With an average treatment time of 4-7 minutes, clinicians can use laser therapy as part of an overall plan of care and maximize the time available to treat.


Small Cone 

Systems: 25W XPi, 15W FXi 

When treating very narrow or precise areas, the Small Cone is ideal due to its smaller spot size. 

Small Massage Ball 

Systems: 40W XLi, 25W XPi, 15W FXi 

Designed to be used with low to moderate power, the Small Massage Ball is ideal for treating trigger points, around the face, or the digits of the feet and hands. 

Flat Window 

Systems: 40W XLi, 25W XPi, 15W FXi 

The Flat Window is great for treating superficial tissues with small to moderate surface areas, especially in the presence of boney prominences. 

Large Massage Ball 

Systems: 40W XLi, 25W XPi, 15W FXi 

The most commonly used on-contact head, the Massage Ball reduces light scatter on the surface while allowing physical compression of tissue. Paired with higher power settings, it is the ideal tool to address problems in the back, hips, and larger muscle groups. 

Large Cone 

Systems: 40W XLi, 25W XPi, 15W FXi 

The Large Cone is designed for offcontact treatments that require higher power settings and is ideal for treating larger areas or when deeper tissues need to be addressed. The Large Cone is not recommended for treatment around the face or over smaller areas due to its larger spot size. 

XL Cone 

System: 40W XLi 

Coupled with the patented Smart Handpiece, the XL Cone has the unique ability to keep high power treatment comfortable for most patients. With a spot size that is twice the size of our Large Cone, it allows clinicians to safely treat large areas and deeper conditions at over 25 Watts of power. 

Rolling Pin 

System: 40W XLi 

LightForce® created the Rolling Pin to allow large areas to be treated with the 40W XLi with a one of a kind, oncontact head that makes treatments simple to administer.



Deep Tissue Laser Therapy™ is used to treat painful muscles and joints associated with acute and chronic soft tissue injuries. It is also indicated for helping relieve pain and stiffness associated with osteoarthritis via its ability to increase localized blood flow. These factors make therapeutic laser a sensible modality choice for post-activity recovery.
