K-Laser (Eltech K-Laser)
The Italian laser that started the Class IV therapy revolution
We Do Not Sell K-Laser Products
ColdLasers.org is not a K-Laser dealer. K-Laser is now sold exclusively through INDIBA in the US. This page is provided as historical reference and to help practitioners understand the confusing K-Laser landscape. If you're looking for comparable Class IV systems, consider these alternatives:
The Laser That Started It All
It's hard to talk about Class IV therapy lasers without acknowledging K-Laser's role in creating the market. Founded in 1999 in Treviso, Italy by Francesco Zanata, Eltech K-Laser was among the first companies to bring high-power therapeutic lasers to clinical practice. Their systems set the benchmark that other manufacturers—including LightForce, Summus, and countless others—would eventually chase.
For years, if you asked a chiropractor or physical therapist about Class IV laser therapy, they'd likely mention K-Laser first. The brand became synonymous with the technology itself. Their Italian craftsmanship, multi-wavelength approach, and sophisticated protocol libraries helped legitimize photobiomodulation therapy as a serious clinical modality.
Many practitioners who now use other brands got their start with a K-Laser. The company's influence on treatment protocols, wavelength research, and dosage standards has shaped the entire industry.
⚠️ The Confusing K-Laser Landscape
If you're researching K-Laser, you've probably encountered some confusing information. Here's what happened:
Francesco Zanata founds the company. The K-Laser brand is born.
Laser Therapy Products, LLC becomes the exclusive US distributor for Eltech K-Laser products.
The US distributor changes its name to "K-Laser USA LLC." This becomes problematic.
Eltech K-Laser discovers K-Laser USA is selling a Chinese-made laser called "Platinum" under the K-Laser brand—without their authorization. Legal battle begins.
During the legal battle, Chattanooga (DJO) temporarily distributes the "real" K-Laser Cube systems in the US.
Arbitration award in Atlanta confirms K-Laser trademark belongs to Eltech K-Laser S.r.l. in Italy. The former distributor is ordered to stop using the K-Laser name.
K-Laser USA rebrands as "Summus Medical Laser" and continues selling Chinese-made systems (Platinum, H1, Horizon) that are NOT K-Lasers.
Eltech K-Laser partners with INDIBA (a Spanish radiofrequency company) for exclusive US and Canadian distribution.
Bottom line: If you want an authentic Italian-made K-Laser today, you must buy through INDIBA. Summus products are NOT K-Lasers and are reportedly manufactured in China by Pioon.
Current K-Laser Products (via INDIBA)
The "real" K-Laser products available through INDIBA include:
Notable K-Laser Features
K-Laser systems have historically offered some unique capabilities:
A single protocol can execute complex sequences—starting with CW at all wavelengths, then pulsing at specific frequencies, then switching to single wavelength, etc. Most competitors offer only single-phase protocols.
K-Laser uses larger diodes (15–20W each) that can be run independently at full power. Many competitors have smaller diodes that lose power when running single wavelengths.
Zoom focus from 15mm (for acupuncture points) to 40mm for broad coverage. One of the only Class IV systems that can do acupuncture, standard therapy, and hands-free treatment.
Articulated arm with swivel head for unattended treatments—a significant accessory that adds versatility.
Software accounts for the six skin phototypes when calculating dosage—one of the few systems that adjusts for melanin content.
Cloud-connected for software updates and optional patient treatment tracking.
🚫 Summus is NOT K-Laser
To be absolutely clear: Summus Medical Laser products (Platinum, H1, Horizon, P4) are NOT K-Lasers.
Summus was the former US distributor that lost the legal battle with Eltech K-Laser. Their products are reportedly manufactured in China by Pioon and have no connection to the Italian engineering that made the K-Laser name famous.
If someone offers you a "K-Laser" that isn't sold through INDIBA, it's not the real thing.
Summus has publicly acknowledged this in legal statements: "Summus Medical Laser is no longer in any way associated with Eltech K-Laser, S.r.l. or the K-laser name."
Considerations
K-Laser systems command top-tier prices ($20,000–$50,000+). The quality is there, but similar functionality is available from other manufacturers at lower price points.
Now only available through INDIBA in the US. This exclusivity can make service, support, and parts availability more complicated than with larger distributors.
The messy history with K-Laser USA/Summus means there's still significant confusion in the market. Used K-Laser equipment may or may not be authentic Italian-made units.
Base models come with only 2-year warranty. The Cube 4 Plus offers 5 years, but you pay extra for it. Many competitors now offer 5 years standard.
The flexibility that makes K-Laser powerful also makes it more complex to operate. The learning curve is steeper than some competitors' more streamlined interfaces.
The excellent accessory system (Extend Plus, various tips, trolley) can add $3,000–$5,000 to the base price.
