Meditation is traditionally associated with stillness: closing the eyes, slowing the breath, quieting external distractions, and gradually turning attention inward.
But what happens when light itself becomes part of the meditation?
A growing area of consciousness and neuroscience research is examining stroboscopic or flicker-light stimulation, the controlled presentation of rhythmic pulses of light, typically experienced with the eyes closed.
Unlike ordinary ambient lighting, these rhythmic pulses can produce remarkably vivid experiences behind closed eyelids. People may perceive moving colors, geometric patterns, tunnels, grids, spirals or other visual forms even though no corresponding images are actually being projected.
More importantly for meditation, rhythmic light can dramatically capture attention and alter a person's perception of time, imagery, emotion, and awareness.
At Kasa Yoga Studios, we are exploring this technology with the ATOM Light by Sage Space Technologies, particularly as a meditation experience that can transition into the deeper auditory environment of a Gong Bath or Sound Bath.
The science behind this emerging field is fascinating, but it is equally important to distinguish what research currently supports from claims that have not yet been established.
What Is Stroboscopic Light Meditation?
Stroboscopic light stimulation, often called flicker light stimulation (FLS) in scientific research, uses rhythmic flashes of light at controlled frequencies.
During many contemporary experiences, the participant lies or reclines comfortably with the eyes closed while a light positioned in front of them changes intensity or pulses according to a programmed sequence.
Closing the eyes does not completely prevent light from reaching the retina. Sufficiently bright light can penetrate the eyelids, and the repetitive visual stimulation is processed by the visual system.
The result can be striking.
Research participants commonly report seeing colors, movement, and geometric imagery despite receiving relatively simple white-light stimulation. Scientific studies refer to these as flicker-induced visual phenomena or flicker-induced visual hallucinations.
A 2021 controlled study published in PLOS ONE found that closed-eye flicker stimulation produced significant short-term alterations in consciousness, particularly vivid geometric and colorful visual experiences. The intensity of the visual phenomena varied considerably between individuals.
A later study found that both the frequency and rhythmicity of the light significantly influenced what participants experienced, demonstrating that these effects are not simply the result of seeing a bright flashing lamp. Rhythmic stimulation produced considerably stronger visual phenomena than comparable irregular stimulation.
Why Can Light Affect the Brain?
One of the mechanisms researchers investigate is called a steady-state visual evoked response.
When the visual system receives rhythmic stimulation, measurable electrical activity in the brain can sometimes begin responding at, or in relation to, the frequency of that stimulation.
This phenomenon is real and well established in neuroscience.
It is frequently described commercially as brainwave entrainment.
There is, however, an important distinction.
Demonstrating that the visual cortex follows a rhythmic stimulus does not necessarily mean that flashing a light at a particular frequency automatically places the entire brain into a predetermined psychological state.
Claims such as “10 Hz always creates an alpha state” or “theta light automatically produces deep meditation” are considerably stronger than the available evidence justifies.
What the evidence does show is that rhythmic visual stimulation can alter patterns of neural activity and create substantial changes in subjective perception and consciousness.
That distinction matters.
At Kasa, we see the technology primarily as a meditation and sensory-exploration tool, rather than presenting it as a medical treatment.
Can Stroboscopic Light Help With Meditation?
This is where the emerging research becomes particularly interesting.
Traditional meditation asks the practitioner to continually return attention to an anchor such as breathing, bodily sensation or a mantra.
For experienced meditators, this process may come naturally.
For someone with an exceptionally busy mind, sitting quietly and trying not to become absorbed in thought can be difficult.
Stroboscopic light changes that equation.
Instead of requiring the meditator to generate the focus internally, the light provides a powerful sensory object that continuously attracts attention.
The changing visual field may make it easier for some people to become absorbed in the present experience.
A large randomized controlled experiment published in Scientific Reports in 2024 studied 262 adults receiving audiovisual stimulation or breath-focused meditation for different durations.
Participants experiencing audiovisual stimulation received programmed pulsed light through closed eyelids along with an atmospheric soundscape. The researchers reported improvements across several self-reported mood measures, including anxiety and negative mood states. Interestingly, some of the benefits of relatively brief audiovisual sessions were comparable to those observed with breath-focused meditation.
The researchers themselves emphasized that the broader evidence for audiovisual stimulation remains mixed and that more rigorous research is needed. The study also had industry-related financial support, which the authors disclosed.
That does not invalidate the results, but it is important context when discussing an emerging wellness technology.
Newer Research on Stress, Absorption and Flow
Research has continued to develop.
A 2026 study published in npj Digital Medicine examined 74 working adults experiencing elevated stress and burnout risk. Participants received an approximately 11.5-minute audiovisual experience using synchronized rhythmic light and sound in either alpha-range or theta-range stimulation protocols.
After the session, researchers observed significant pre-to-post improvements in reported anxiety, mood disturbance, perceived stress, vitality and measures related to psychological flow and absorption.
However, this was an uncontrolled exploratory study, meaning there was no non-treatment comparison group. The researchers explicitly stated that controlled studies are needed before concluding that the stimulation itself caused all of the improvements. The technology company involved in the system also contributed financial and technical support, which was disclosed by the authors.
This is an excellent example of how we approach the science at Kasa:
Promising does not mean proven.
Stroboscopic meditation is an intriguing and increasingly researched experience, but it should not be marketed as a cure or medical treatment.
A Different Kind of Closed-Eye Experience
One of the most remarkable aspects of stroboscopic meditation is that white light does not necessarily look white once the eyes are closed.
Participants frequently describe elaborate colors and geometrical structures.
Researchers have documented patterns including spirals, tunnels, lattices, grids, honeycomb-like forms, and moving shapes.
The lamp does not project these images.
They arise from the interaction between rhythmic sensory stimulation and the participant's own visual system and brain.
This means two people can experience the same light program very differently.
One person might experience extensive color and imagery.
Another may see relatively simple flashes or shapes.
Someone else may primarily notice bodily sensations, changes in time perception or mental quiet.
Individual differences are normal. Research has even found that visual imagery ability may influence the complexity and vividness of flicker-induced visual experiences.
There is therefore no “correct” experience.
Light and Sound: An Especially Interesting Combination
A 2024 study published in Frontiers in Psychology specifically examined flicker light stimulation and music.
Twenty participants listened to emotionally evocative music both with and without flicker stimulation.
When flicker light was added, participants reported significantly stronger music-evoked emotional responses, particularly in dimensions associated with energetic or joyful emotional activation. The intensity of the flicker experience was also associated with greater emotional arousal.
That is particularly relevant to sound-based meditation.
The study does not prove that stroboscopic light makes gong therapy more effective.
But it does provide experimental evidence that flicker stimulation can change how people experience sound and music emotionally.
And that creates an interesting bridge between light meditation and the immersive acoustic environment of a sound bath.
Why Follow the Light Experience With a Gong Bath?
At Kasa, we are especially interested in a particular sequence:
Light → Stillness → Sound
Rather than viewing stroboscopic light and the gong as competing experiences, they can serve very different roles within the same contemplative journey.
The light experience can create intense visual engagement and rapidly turn attention inward.
Then the visual stimulation ends.
The participant remains comfortably resting with eyes closed.
Instead of immediately returning to conversation, phones, movement and ordinary sensory stimulation, the experience transitions into sound.
The gongs, Himalayan singing bowls, crystal bowls, chimes and other instruments can then become the next focus of attention.
Scientifically, we cannot yet say that this exact sequence has been proven superior to either modality alone.
No high-quality clinical trial has specifically tested an ATOM Light session immediately followed by a live gong bath.
But there is research supporting both sides of the experience independently.
A randomized controlled study found that a single Tibetan singing bowl session produced reductions in self-reported anxiety and changes in heart-rate variability consistent with an acute relaxation response.
Another randomized crossover study found that Himalayan singing-bowl exposure before directed relaxation produced greater reductions in heart rate and systolic blood pressure than silence before the same relaxation exercise.
And a 2025 systematic review examining 14 quantitative studies concluded that Tibetan singing-bowl interventions show potential for reducing stress and anxiety and improving psychological well-being, while also emphasizing that more rigorous controlled trials are needed.
Taken together, this creates a scientifically reasonable—but still investigational—rationale for using light to initiate an inward state and sound to continue the contemplative experience.
From Visual Stimulation to Auditory Immersion
There is another reason we like this sequence.
Stroboscopic stimulation can be intense.
A Gong Bath afterward provides an opportunity for the visual stimulus to disappear while the participant remains in a quiet, supported environment.
Attention gradually shifts from seeing to listening.
From light to vibration.
From active visual phenomena to sustained tones and spaciousness.
That transition may be just as meaningful as either technology alone.
Rather than ending an intense sensory experience abruptly, the sound bath becomes a form of experiential integration.
We use that term intentionally.
It does not imply that the gong is neurologically “locking in” a brainwave state or permanently changing the nervous system—claims for which convincing evidence does not currently exist.
Instead, integration describes something much simpler: allowing time for the participant to remain still, observe what they are experiencing and transition gradually back toward ordinary awareness.
The ATOM Light at Kasa Yoga Studios
The system currently used at Kasa is the ATOM Light by Sage Space Technologies.
According to the manufacturer, the current ATOM Light uses 12 high-powered RGBW/RGBY LEDs and provides adjustable light intensity, frequency, and programmed sessions. It can deliver white-light stroboscopic stimulation as well as separate colored-light programs.
One feature particularly relevant to a sound-focused studio is ATOM's sound-reactive mode.
The manufacturer states that the system can respond to an external audio source in real time, allowing light behavior to interact with music or other sound.
For our purposes, the most important aspect is not making extraordinary medical claims about the equipment.
It is the ability to create a controlled, immersive meditation environment in which light, attention and sound can interact.
ATOM Light vs. PandoraStar
People researching this technology may also encounter the PandoraStar, one of the better-known devices in this category.
The basic concept is similar.
PandoraStar's manufacturer describes a system of 12 stroboscopic LEDs viewed through closed eyes, using programmed flicker frequencies designed to produce closed-eye visual experiences and support meditation or altered-state exploration.
ATOM therefore belongs to the same broad family of closed-eye flicker-light technologies.
There are some practical differences.
ATOM combines its 12-LED stroboscopic system with colored-light capability, adjustable programming and its proprietary real-time sound-reactive function. According to its manufacturer, ATOM currently offers multiple programmed experiences and adjustable intensity and frequency controls.
PandoraStar similarly uses 12 LEDs and programmed frequency-based stimulation.
What is more important scientifically is what we cannot say.
There is currently no high-quality independent head-to-head clinical study demonstrating that ATOM is neurologically or therapeutically superior to PandoraStar.
For that reason, we prefer to discuss their technological differences rather than making unsupported claims about one producing better health outcomes.
At Kasa, we focus on ATOM simply because it is the system we have chosen to work with and incorporate into our studio experiences.
Could This Make Meditation Easier?
Possibly, and this may ultimately be one of the most useful applications of the technology.
Many people believe they are “bad at meditation” because their thoughts continue when they close their eyes.
That is not unusual.
But the constantly evolving visual experience generated by flicker light gives attention something compelling to observe.
Instead of trying to force the mind to become blank, the practice becomes observational:
Notice the colors.
Notice the patterns.
Notice the movement.
Notice the breath.
Notice thoughts appearing and disappearing.
Notice how the experience changes when you stop trying to control it.
In this respect, stroboscopic meditation can function almost like a highly engaging object of mindfulness.
The light does not perform meditation for you.
But for some people, it may help create the conditions in which sustained inward attention becomes easier.
What Are the Potential Benefits?
Based on current research, the most defensible potential applications of stroboscopic or audiovisual light meditation include supporting short-term relaxation, focused inward attention, absorption, altered perception, emotional engagement with music, and temporary improvements in certain measures of mood or anxiety.
Research also suggests that rhythmic stimulation can produce measurable frequency-following responses in the visual system.
What has not been established is equally important.
Current evidence does not justify claiming that ordinary wellness sessions with stroboscopic light treat neurological disease, cure anxiety or depression, permanently “rewire” the brain, detoxify the body, open specific energy centers or guarantee a particular brainwave state.
Those are much stronger claims than current human evidence supports.
Safety Matters
Stroboscopic light is powerful sensory stimulation and is not appropriate for everyone.
The most important established concern is photosensitive seizure risk.
The Epilepsy Foundation reports that certain flashing visual stimuli can trigger seizures in susceptible individuals and notes that flashes roughly within the 5–30 Hz range are among those most likely to be provocative, although sensitivity varies substantially from person to person. Importantly, some people may not know that they are photosensitive until they experience a visually triggered seizure.
The ATOM manufacturer specifically states that stroboscopic use is contraindicated for individuals with photosensitive epilepsy or a history of seizures.
Scientific studies in this field also commonly screen out participants with epilepsy, seizure history, significant photosensitivity, and, in some protocols, migraine or certain eye conditions. One large 2024 audiovisual-stimulation study excluded participants with epilepsy, seizures, migraines, photosensitivity, and several ocular conditions.
For that reason, responsible studio use requires screening, informed consent, adjustable intensity, and the ability to stop the experience immediately if someone becomes uncomfortable.
Anyone with a history of seizures, suspected photosensitivity, or significant sensitivity to flashing light should consult an appropriate healthcare professional before participating.
Stroboscopic light experiences are wellness and meditation practices—not substitutes for medical or mental-health care.
Where Ancient Practice Meets Emerging Technology
Sound meditation is ancient.
Programmable LED neurostimulation is very new.
And somewhere between the two is a fascinating new approach to contemplative practice.
Stroboscopic light provides the visual system with rhythm.
The mind responds with patterns, colors, movement and sometimes profound absorption.
Then the light disappears.
The room becomes still.
And the gong begins.
At Kasa Yoga Studios, that transition is what interests us most.
Not technology replacing meditation.
Not technology replacing sound.
But technology becoming another doorway into the same thing contemplative practices have explored for thousands of years:
attention.
presence.
stillness.
And the experience of discovering what happens when, for a little while, we turn away from the outside world and listen inward.
