We live too much under artificial light
We spend most of the day indoors, in front of screens — and barely get the red and infrared part of natural light our bodies evolved with. After sport or a long day, mindful recovery often falls short.
Little natural light
We spend around 90% of our time indoors — the red and near-infrared part of light is almost completely missing from daily life.
Recovery falls short
After training, sport or an intense day, the mindful pause in which body and mind can wind down is often missing.
Big panels, little everyday use
Many red-light solutions are large, stationary panels — impractical for sport, training and on the go.
All statements describe wellness and wellbeing. The [B4A] PBM is not a medical device; no healing claims are made.
A mindful light ritual
The [B4A] PBM brings red and near-infrared light mindfully into your routine. For the moment when you consciously wind down.
Red + near-infrared together
660 nm for surface-near, 810 nm for deeper structures — always emitted together. Surface and depth in one device.
The right light window
With photobiomodulation, the right window matters, not the maximum.
Built for your daily life
Cordless, one button, robust aluminium housing — on the sofa, at the desk, in the sports bag or when travelling.
How photobiomodulation works at the cellular level
This is how research describes the mechanism: red light (660 nm) and near-infrared (810 nm) penetrate the tissue and reach the mitochondria — the "powerhouses" of the cell. This is where photobiomodulation (PBM) takes effect.
The mitochondrial hub: cytochrome c oxidase
Red and near-infrared light is absorbed by cytochrome c oxidase (Complex IV) in the inner mitochondrial membrane. This enzyme is the key of the respiratory chain — it is considered the central light acceptor (chromophore) of PBM.
1 · More ATP — more cellular energy
Activating cytochrome c oxidase strengthens the proton gradient. Research associates this with an increased ATP production — more available energy that can support the cell's natural processes.
2 · Less mitochondrial stress
At the same time, a lower formation of reactive oxygen species (ROS / free radicals) is described — which can reduce oxidative stress at the cellular level and support cell regulation.
3 · Cellular signalling pathways
The rise in ATP and the modulation of ROS are considered triggers of cellular signalling cascades associated with balanced regulation processes and the body's own regeneration — processes that can support wellbeing.
Not only local — the systemic perspective
Current research describes that PBM doesn't act only on the irradiated tissue: a local application can reach more distant regions via circulating factors — an approach that can support microcirculation broadly.
Why does it work in humans?
Muscle, tendon and connective-tissue cells have a high mitochondrial density — exactly the target structure of PBM. Red light reaches surface-near structures (approx. 5–10 mm), near-infrared medium depths (up to approx. 20–30 mm) — suitable for muscles and deeper tissue.
| Level | Effect described in PBM research |
|---|---|
| Mitochondrial | ATP ↑ · ROS ↓ |
| Cellular | cell regulation & cell survival supported |
| Tissue | circulation ↑ · regeneration ↑ |
| Systemic | circulating, regulating factors |

The right approach instead of raw power
Infrared-focused: more 810 nm
8 of the 14 LEDs are near-infrared. NIR physically has a greater penetration depth than red light — the [B4A] PBM deliberately focuses more on depth than many comparable devices.
Selectable 10 Hz pulse
Continuous light or pulsed at 10 Hz. Pulsed photobiomodulation is an active research field; the choice is yours.
One button. Deliberately simple.
No display, no app: Press — red + infrared on. Hold 3 seconds — 10 Hz pulse. Press again — off. One-hand operation.
LED — not laser
14 high-power LEDs, red and infrared combined. Photobiologically tested to EN 62471, Risk Group 1 — no safety goggles required; do not look directly into the light source.

Frequently asked questions about the [B4A] PBM
What is the [B4A] PBM?
A handy battery-powered device for light wellness. It combines red light (660 nm) and near-infrared (810 nm) for your personal recovery and relaxation ritual. A wellness product, not a medical device.
Is the [B4A] PBM designed for people?
Yes. This version is intended as a wellness device for people — as a recovery ritual after sport, for relaxation in the evening or as a mindful break in everyday life. For use on animals we have a separate offering.
Can I also use the device on animals?
It is essentially the same light — for use on animals (horse and dog) we offer a dedicated version with its own landing page and an application section tailored to animals. This page describes the [B4A] PBM as a wellness device for people.
What does photobiomodulation (PBM) mean?
PBM describes how light of certain wavelengths is absorbed by cells and triggers biological processes there — above all in the mitochondria, the "powerhouses" of the cell. Red and infrared light are considered the relevant wavelengths for this.
Why 660 nm and 810 nm together?
660 nm acts more on the surface, 810 nm penetrates deeper and reaches muscles and deeper tissue. The [B4A] PBM always emits both wavelengths together, covering surface and depth.
What can I use it for?
As part of your recovery routine: as recovery after sport, for muscular relaxation, as an evening ritual and for general relaxation. It can provide supportive care for wellbeing — it is not a medical device and makes no healing claims.
Do I need safety goggles?
No. The [B4A] PBM is photobiologically tested to EN 62471 and classified in Risk Group 1 (low risk) — safety goggles are not required. As with any bright light source: do not look directly and deliberately into the LEDs.
PBM or PEMF — which first?
As a practice-proven recommendation: first PBM, then PEMF. Red and near-infrared light penetrates best into undisturbed tissue. PEMF increases blood flow — more haemoglobin in the tissue absorbs the light and reduces penetration depth. If you use the light first, it uses the full "optical window".
Note: The combination of PBM + PEMF is an active research field without robust sequence studies. A practice-oriented recommendation, not a proven synergy.
How do I operate the device?
One button: press — red + infrared light up together. Hold for 3 seconds — 10 Hz pulse mode. Press again — off. No display, no app, operable with one hand.
How long does an application take?
It depends on the distance. As a rough guide: at contact a few minutes per point, and correspondingly longer at greater distances.
Battery and charging?
10,000 mAh battery (3.7 V / 37 Wh), charging via USB-C. If capacity declines, the battery can be replaced via our service — not the whole device.
Which certifications and tests does the [B4A] PBM have?
The [B4A] PBM is CE marked and complies with the relevant EU directives and standards:
• Eye & light safety (EN 62471): Risk Group 1 – low risk, no safety goggles required (exempt in 10 Hz pulse mode)
• EMC Directive 2014/30/EU: tested to EN 55032 / EN 55035 (Class B)
• RoHS Directive 2011/65/EU (+ 2015/863): restriction of hazardous substances (EN IEC 63000)
• Battery: EU Battery Regulation 2023/1542, UN 38.3 (transport), IEC 62133-2 (battery safety)
Is this a medical device?
No. The [B4A] PBM is a wellness product for people. No medical, therapeutic or healing effects are claimed.
