810nm Research
- 808 nm LED Accelerates Burn Wound Healing in Rats
In rats with serious burns, daily 10-minute treatments with 808 nm LED light (practical overlap with 810nm) for a week lowered inflammation, encouraged new cell and collagen growth, and helped the wounds close faster, working just as well as a laser for quicker recovery.
- 810 nm LED Promotes Diabetic Wound Healing in Cells and Mice
Lab tests on cells and experiments on diabetic mice showed that 810 nm LED light helped cells grow and move to close wounds faster, while boosting proteins that aid healing, making it a good option for tough-to-heal diabetic sores.
- LED Light Therapy (Including Around 810 nm) Enhances Wound Repair
A review of multiple studies found that LED lights at wavelengths like 830 nm (very close to 810 nm) reduce swelling, increase skin cell and collagen production, and form new blood vessels and tissue, speeding up wound healing in lab and animal tests.
- 810 nm LED with Portable Device Aids Skin Wound Healing in Lab Model
Using a handheld LED device at 660 nm and 810 nm on a 3D model of human skin, the light helped the model 'wounds' shrink and heal by influencing key healing chemicals, suggesting it could be useful for treating real skin injuries safely at home.

830nm Research
- 830 nm LED (and Similar Wavelengths) Promotes Wound Healing Like Lasers
A review of studies showed that LED therapy at wavelengths like 830 nm increases fibroblast growth, collagen production, and new blood vessels, speeding up wound closure and tissue repair in both lab and animal models, with effects similar to lasers for safe, non-invasive injury healing.
- 830 nm LED Enhances Diabetic Wound Healing in Rats
In diabetic rats with skin wounds, 830 nm LED therapy over 14 days boosted collagen production, new blood vessels, and tissue growth, leading to faster wound closure and better healing compared to controls.
- 830 nm LED (and Other Wavelengths) Effective for Burn Wound Treatment
A systematic review and meta-analysis of photobiomodulation for burn wounds found that wavelengths including around 830 nm significantly reduced healing time, inflammation, and scarring in animal models, supporting its use for faster injury recovery.
- 830 nm LED Low-Level Therapy Heals Various Wounds in Patients
In a preliminary study on patients with different wounds (like pressure ulcers and burns), 830 nm LED treatments achieved full healing, controlled infection and pain, with treatment times varying by wound condition, proving safe and effective for clinical use.
- 830 nm LED Promotes Cutaneous Wound Healing
A review highlighted that 830 nm near-infrared LED light is highly effective for healing impaired skin wounds by reducing inflammation, boosting cell proliferation, collagen, and blood vessels, based on multiple lab and animal studies.
- 830 nm LED Has Systemic Effect on Burn Wound Healing
Applying 830 nm LED light to the abdomen of mice and rats with burn wounds on their backs led to faster healing of the burns than in untreated animals, showing a body-wide benefit for injury recovery.

Did you know near-infrared (NIR) light is beyond our vision range? That’s why you won’t see our 810nm, 830nm, and 850nm LEDs — even though they’re working just as powerfully as the visible 630nm and 660nm ones
