About This Product

System Overview & Clinical Positioning

The MR4 LS50 is a significant step up from the MR4 Pro, built around the LS50 LaserShower emitter which incorporates four GaAs super pulsed diodes delivering 50,000mW of peak power across a 20cm² treatment area. The larger array covers five times more area than the SE25 and delivers double the power, cutting therapy times by over 50% while increasing depth of penetration. This makes the LS50 the preferred choice for practitioners treating large anatomical structures, spinal conditions, or high-volume patient schedules.

Higher Photonic Density for Superior Results

The LS50 delivers the highest photonic density saturation of any MR4 product. Its 12-diode array (4 super pulsed lasers, 4 infrared SLDs, 4 red LEDs) creates a broad, uniform energy field that stimulates greater systemic therapeutic effects. This makes the LS50 particularly effective for complex multi-joint conditions, chronic pain syndromes, and post-surgical rehabilitation requiring broad-area coverage.

Frequently Asked Questions

How is the LS50 different from the SE25 emitter?
The LS50 has 4 super pulsed laser diodes delivering 50,000mW peak power over a 20cm² area—that is double the power and 5× the coverage of the SE25. The larger treatment head is ideal for spine work, large muscle groups, and unattended treatments. The SE25 is better for targeted point treatments and is probe-compatible.
Can I add a second emitter to the LS50 system?
Absolutely. The MR4 console has 3 output ports. You can add an SE25 emitter or a second LS50 at any time. Running two emitters simultaneously allows you to treat bilateral conditions or two areas at once, further reducing treatment times.
Is the LS50 compatible with the probe set?
No. The LS50 LaserShower emitter is not compatible with the PS-4 probe set due to its larger multi-diode head design. If you need probe capability for acupuncture or trigger point work, consider adding an SE25 emitter to your system.
What makes the LS50 better for large-area treatments?
The LS50 has the highest photonic density saturation of any MR4 emitter. Its 4 laser diodes and 20cm² array deliver uniform energy across a broad area, making it ideal for treating the spine, hip, shoulder, thigh, and other large structures. The smooth head design allows easy repositioning during treatment.
