Light Neurostimulation
No guided meditation. No substances. No beliefs required. Just pulsed light. And your brain does the rest.
When light pulses at a precise frequency in front of your closed eyelids, your brain naturally synchronises its own waves to that frequency. This is the Frequency Following Response - or brainwave entrainment.
The result: a targeted, reproducible mental state - no hypnosis, no guidance, no imposed content. The experience is 100% yours - unique to each session, unique to each brain.
The light pulses. Your brain synchronises. That's all - and that's already a lot.

You settle in comfortably - seated or lying down, eyes closed - facing the lamp. A short introductory programme (3–5 min) adjusts the light intensity to your sensitivity and ensures you're at ease with the process.
Then the main programme starts - usually accompanied by music. You don't have to do anything. Your brain perceives the light pulses through your eyelids and naturally synchronises its own waves to the proposed frequency. This is the Frequency Following Response.
The result varies depending on the chosen programme: deep relaxation, focus, energy boost, or inner exploration. The 5 frequency bands below each correspond to a distinct mental state.
Sessions are personalised based on what you're looking for. Here are the most requested.
For those who struggle to get started, maintain attention or manage mental overload. A programme built on frequencies associated with alert attention (SMR, beta, gamma), without stimulants. The effect varies from person to person.
Truly unwinding, not just taking a break. A state of muscular and mental release that many never reach naturally - not even on holiday.
Leave with energy and a drive to act. Gamma sessions activate brain coherence and the flow state. Perfect in the morning or before anything that demands mental sharpness.
For the curious. Exploration programmes induce rich hypnagogic states - geometries, colours, a sense of weightlessness - without any substance. An experience hard to describe, easy to live.
Sceptics welcome. The lamp doesn't need you to believe in it to work.
Who wants to decompress quickly, deeply, and leave with a clearer head.
Concentration issues, procrastination, exam stress. A session can help you settle before working.
Who already meditates or wants to go deeper into self-knowledge, without imposed content.
Who wants to experience it to understand, not to believe. Scientific approach is welcome.
This testimonial illustrates something few people anticipate: the lamp doesn't just relax the body - it can help release what overflows. A deep emotional liberation, without conscious effort, in just a few minutes.
I was in the thick of a crisis and my emotions were running high. As soon as the programme started, I let those emotions flow. Tears streamed down my face. Then I relaxed, and certain muscles began to twitch. I felt a deep sense of relaxation, breathing deeply as the tension in my body eased. White, orange, red, and blue lights; a test pattern with a kaleidoscope in the centre.
Came in early for a boost. I relaxed almost immediately. I loved the music right away and felt like I was in a bubble. With the little blanket, the warmth wrapped around me and I felt safe. A kaleidoscope of shapes and yellow-orange hues, it was beautiful.
"Good Morning World" session (7Hz, 14Hz, 40Hz) followed by "Motivation Creation" (Gamma 40Hz). The music accompanied perfectly. A real boost before a busy day.
I treated myself to a special roXiva motivation session. My review to myself:
- I had an amazing motivating session.
- And what did you see?
- Light, orange, and yellow.
- Is that all?
- I heard myself snoring and fell asleep 😂
Brainwave entrainment is not a belief. It is a measurable neurophysiological mechanism - studied in laboratories for over 90 years.
Adrian and Matthews record, in Brain, the brain's rhythm following a flickering lamp. Photic driving has a start date.
British neurologist William Grey Walter documents, via EEG, how the brain synchronises with a strobe light - and the intense visual experiences it produces with eyes closed, without any substance.
Kroger and Schneider publish one of the first clinical uses of flickering light: inducing hypnosis. Through the 1960s the device is used for pain relief in labour and as an aid to anaesthesia.
A review of 20 clinical studies on the psychological effects of brainwave entrainment: attention, stress, anxiety, cognitive support. Modest but consistent effects across protocols.
Li-Huei Tsai's team publishes in Nature: 40 Hz flickering light reduces Alzheimer's markers in mice. The current field starts here.
Bartossek and colleagues measure what flickering light does to the lived experience of 24 participants - not only to the EEG.
A two-year follow-up of 40 Hz light and sound in 5 Alzheimer's patients: in the 3 women with late-onset disease, cognition held up better than in matched cohorts. Encouraging, but a very small sample.
Six areas under study. Leads, not promises.
The area with the longest human follow-up. Daily 40 Hz light and sound, one hour a day, has been tested in Alzheimer's patients for 3 months, 6 months, then about 2 years, with measures ranging from memory recall to brain volume. These are very small trials, run by teams linked to the company developing the device: encouraging leads, not proof.
Sounds timed to the slow waves of deep sleep have been tested, with reported effects on memory and on the hormonal profile of sleep. On the 10 Hz side, a pilot of 28 people with chronic pain (30 minutes before bed for 4 weeks, mostly audio) reported in sleep diaries 29 more minutes of sleep and 13 minutes less to fall asleep. Wrist actigraphy did not confirm it and there was no control group: a signal, not a result.
Trials have tested 10 Hz stimulation (light or sound) in chronic pain patients, including a randomised crossover trial against a sham in fibromyalgia. More alpha activity goes with less reported pain (a modest correlation). Clinical gains remain small: about 0.5 points out of 10 for night-time pain.
Three frequencies of flickering light (theta, alpha, beta) were compared for their effect on the autonomic nervous system in 62 students: the largest drop in blood pressure came with theta in non-depressed participants, while in depressed participants markers of sympathetic activity went up. There was no sham condition. On controlled evidence, rhythmic sound is better studied than light.
A Berlin team (Freie Universität and Charité) has spent several years measuring what flickering light does to what people see and feel. Visual effects (colours, geometric patterns) are strongest around 10 Hz, vary a great deal from person to person, and involve the thalamus and visual areas. It is the published research closest to a session.
10 Hz flicker applied to on-screen stimuli slowed selective attention, more so the closer a person's own alpha rhythm was to 10 Hz: interference, not improvement, but a hint that matching your own rhythm matters. A meta-analysis of 22 studies on binaural beats found a medium effect (about 0.45) on memory, attention, anxiety and pain. The brain signature of flow has been mapped separately.
These studies used other devices than the lamps used here: they document mechanisms and leads, not the effect of a ThinkClear session.
The mechanism is solid. The deeper effects - meditation, hypnagogic states, subjective experiences - have been described for decades but remain difficult to quantify in a laboratory. This does not mean they do not exist: only that objectively measuring an inner experience is, by nature, limited.
This is why the lamp is not a medical device and does not claim to diagnose, treat, or cure. It is a tool for exploration and wellbeing - grounded in a known mechanism, without over-interpreting what it produces.

I come from the IT world: a developer and analyst by training, which is where I learned rigour. I have always been drawn to whatever sparks my curiosity, to energies and to what the eye cannot see. Several years ago, looking for a different sense of direction in my life, I stumbled on a podcast about the PandoraStar. I went for it. Out of curiosity, not belief.
I wanted to understand: what really happens in the brain? Why do some people relax deeply within a few minutes? Which energies are at play, and how does it work?
I trained and was certified by the PandoraStar team. I worked a lot on myself and explored what is possible, together with my wife. I then added a second lamp, the roXiva. Since then I have been supporting people with very varied profiles. ThinkClear is the simple, honest version of what I do: helping people reach useful mental states, without needless mystery.
Available for individual sessions, workshops and demonstrations, on request.
I have always been passionate about the invisible, about energies and about caring for others. I have taken many trainings around these themes: Essene healing, massage, aura reading, psychology… I wanted to add strings to my bow, for myself and to help others.
It was only natural for me to follow Emmanuel on his adventure. The lamps showed me a side of myself I did not know. I wanted to put all this knowledge at the service of those who need it. It also led me to create “Sortir du rouge” (“Out of the red”), to help women dealing with mental overload.
I trained and was certified at the same time as Emmanuel. Since then I have been supporting him in his ThinkClear mission.
