If you're researching the Kala red light therapy wavelength specs before buying, this page has every number you need — organized by product, with irradiance, LED counts, power ratings, and EMF data in one place. No fluff, just the technical reference I wish existed when I was comparing devices for my clinic.
Kala product specs at a glance
Kala makes six light therapy devices across panels, face devices, and a hat. Each product targets a different use case — and the wavelengths reflect that. Panels use therapeutic infrared penetration wavelengths. The mask adds blue light for acne. The hat uses a shallower red wavelength tuned for scalp tissue.
The table below covers every current device. For context on why these numbers matter, see my explainer on what irradiance means in red light therapy — it's the single most important spec most buyers overlook.
| Product | Wavelengths | LED Count / Type | Irradiance | EMF |
|---|---|---|---|---|
| Kala Mini 2.0 | 660nm red + 850nm NIR | 5W clinical-grade LEDs | Targeted / portable | Zero from 4–6 inches |

What these wavelengths actually do
Wavelength (measured in nanometers, nm) determines how deep light travels into tissue. Think of it like radio frequencies — different wavelengths do different jobs. Understanding the difference between near-infrared and red light helps you choose the right Kala device for your goal.
| Wavelength | Type | Penetration Depth | Primary Uses | Kala Products |
|---|---|---|---|---|
| 415nm | Violet/blue | Surface only | Antibacterial, acne (kills P. acnes bacteria) | Therapy Wand |
| 465nm | Blue | Skin surface | Acne treatment, sebum regulation | Face Mask |
| 630nm | Red | 1–2mm (epidermis/dermis) | Collagen production, wound healing, skin rejuvenation | Face Mask, Therapy Wand |
| 650nm | Red | 2–3mm | Hair follicle stimulation, scalp circulation | Red Light Hat |
| 660nm | Red | 3–5mm | Muscle recovery, inflammation, skin health | Mini, Pro, Elite, Sauna Panel |
| 830nm | Near-infrared | 10–20mm | Deep tissue anti-inflammatory, skin rejuvenation | Face Mask |
| 850nm | Near-infrared | 20–30mm+ | Joint recovery, nerve tissue, deep muscle, bone | Mini, Pro, Elite, Sauna Panel |
Kala Pro and Elite panel specs in detail
The Pro and Elite panels share the same core technology — 5W clinical-grade LEDs at 660nm and 850nm — with the Elite offering a larger coverage footprint. Both include Kala's Pulse Recovery+ mode, which lets you select pulsed delivery frequencies instead of continuous light.
| Spec | Kala Pro Panel | Kala Elite Panel |
|---|---|---|
| Wavelengths | 660nm + 850nm | 660nm + 850nm |
| LED power | 5W clinical-grade | 5W clinical-grade |
| Coverage | Half-body | Full-body |
| EMF at 6 inches | Zero | Zero |
| Pulse Recovery+ modes | 292 Hz, 586 Hz + custom | 292 Hz, 586 Hz + custom |
| Timer settings | 10 / 15 / 20 min | 10 / 15 / 20 min |
| Display | Digital dash smart screen | Digital dash smart screen |
| LED lifespan | 50,000+ hours | 50,000+ hours |
| FDA registration | 3016171836 | 3016171836 |
| Testing | 50 hours per device | 50 hours per device |
Kala Face Mask specs in detail
The Kala mask is the most spec-dense device in the lineup. It delivers three separate wavelengths simultaneously — something most competing masks don't offer. The 465nm blue channel is the key differentiator: it targets acne-causing bacteria at the skin surface while the red and NIR channels work on collagen and deeper inflammation.
| Spec | Detail |
|---|---|
| Red wavelength | 630nm |
| NIR wavelength | 830nm |
| Blue wavelength | 465nm |
| Red irradiance | 20 mW/cm² |
| NIR irradiance | 10 mW/cm² |
| Blue irradiance | 10 mW/cm² |
| Total LEDs | 66 triple-chip medical-grade |
| Dimensions | 298mm × 216mm × 5.1mm |
| Material | Medical-grade silicone |
| Charging | USB-C, ~4 hours full charge |
| Battery | Lithium-ion |
| Warranty | 2 years |
| FDA clearance | Class II Medical Device |
"The Kala mask's 20 mW/cm² at 630nm is strong for a flexible silicone mask — most wearable masks I've tested deliver 10–15 mW/cm² at the skin surface. That extra output means shorter sessions to reach the therapeutic dose window. I use it for 10 minutes, which comfortably hits the 2–4 J/cm² range research supports for collagen stimulation." — Daryl Stubbs, CAT(C), RMT, Holistic Nutritionist
Pulse Recovery+ frequency reference
The Pro and Elite panels go beyond standard continuous light delivery. Kala's Pulse Recovery+ mode pulses the LEDs at specific frequencies — each associated with different physiological effects in the research literature.
| Mode | Frequency | Associated Benefits |
|---|---|---|
| Standard | Continuous (no pulse) | Default mode — skin health, general recovery, most users |
| Pulse Recovery+ Low | 292 Hz | Anxiety reduction, sleep quality, chronic pain, wound healing |
| Pulse Recovery+ High | 586 Hz | Depression, anxiety, chronic pain, insomnia, seasonal affective disorder |
| Custom | User-set via digital dash | Adjustable for specific protocols |
Why these specs matter for treatment decisions
As a certified athletic therapist, I look at three numbers when evaluating any red light device: wavelength, irradiance, and LED quality. Wavelength tells me what tissue depth I'm targeting. Irradiance tells me how long a session needs to run to deliver a therapeutic dose. LED quality determines whether that irradiance holds up over years of use.
Kala's 5W LEDs on the panels are clinical-grade — most budget devices use 3W or lower. The 50-hour pre-testing protocol per device also matters for consistency. A 2016 review confirmed that photobiomodulation works through mitochondrial cytochrome c oxidase stimulation, and dose precision is key to consistent results (de Freitas & Hamblin, PMC5215870). If your irradiance is inconsistent, your results will be too.

Frequently asked questions
What wavelengths does Kala use?
Kala panels (Mini, Pro, Elite, Sauna) use 660nm red and 850nm near-infrared. The Kala Face Mask uses three wavelengths: 630nm red, 830nm near-infrared, and 465nm blue. The Therapy Wand uses 630nm red and 415nm blue. The Red Light Hat uses 650nm red.
What is the irradiance of the Kala mask?
The Kala Red Light Face Mask delivers 20 mW/cm² at 630nm red, 10 mW/cm² at 830nm near-infrared, and 10 mW/cm² at 465nm blue. These are measured at treatment distance using 66 triple-chip medical-grade LEDs.
What does nm mean in red light therapy?
nm stands for nanometer — the unit used to measure light wavelength. In red light therapy, wavelength determines how deeply light penetrates tissue. 630–660nm red light penetrates the skin surface and is used for collagen, acne, and wound healing. 810–850nm near-infrared light goes deeper into muscle, joint, and nerve tissue.
