Lucia Light

Here's What's Happening


New Study Suggests a Legal Alternative to Psilocybin – Flickering Light

Taking “magic mushrooms”, “LSD” or other psychoactive drugs is definitely one way to explore consciousness, but have you ever wondered if there was a safer alternative?  A recent study by Dr. David Schwartzman and his team at the University of Sussex now suggests that flickering light can induce similar states of awareness that psilocybin does.

Dr. Schwartzman and his team collected data on brainwave measurements, neural activity and experiential reports during wakeful rest, a psilocybin experience and an experience with the stroboscopic Lucia N°03.

They concluded that: “the ability of stroboscopic stimulation to induce altered phenomenology with marked similarities to psychedelic ASC, along with similar changes in neural activity (increased signal diversity, reduced alpha power), suggests it may provide an alternative to or adjunct method alongside psychedelic therapy.” (Schwartzman, et. al, 58-59)

Psychedelic substances have been making a comeback in clinical trials but this study shows the possibility of accessing similar states of consciousness and the correlated benefits without ingesting any substances. Instead, these states of consciousness can be accessed with light: specifically a solid and stroboscopic light called the Lucia N°03.

This is great news for anyone who wants to explore the benefits that psychedelics can initiate without ingesting any substances, or for anyone wanting to supplement and integrate their psychedelic experiences through another medium.


​What is the Lucia N°03?

Developed at the base of Tyrolean Alps in Austria, the Lucia N°03 is a system that uses solid and flickering light to induce an altered state.  It was created by Dr. Engelbert Winkler (psychologist, hypnotherapist and legal consultant for youth) and Dr. Dirk Proeckl (medical neurologist and psychiatrist) nearly a decade ago.  

Following  the age-old tradition of using flickering light to get into a meditative state (think campfires), the Lucia N°03 invites the light traveler into a expanded state of consciousness. It is also known as a “hypnagogic light machine” referring to the dreamy place between wakefulness and sleep. Reported benefits include: clarity, increased creativity, deep relaxation, inner peace and other-worldly experiences.

Similar to reported benefits of psychedelic substances such as psilocybin, the Lucia N°03 invites the light traveler to let go of the stresses of daily life and relax into a beautiful world of colors, patterns and images created by their own brain.


What are You Truly Experiencing? Measuring States of Consciousness Within the Brain

While self-reports from experiences in altered states have been around for decades, some members of the scientific community have been seeking out the best ways to track and analyze them within the brain.

The most well-known method for measuring states of consciousness within the brain is through brainwave measurements using an EEG. This is a tool that measures the amplitude of different brain waves such as beta, alpha, theta, delta and gamma. This method has been helpful for understanding certain aspects of conscious experience, particularly in relation to meditative and spiritual experiences. Findings show a correlation between reduced alpha power and coherency within the brain.

However, recent studies on ketamine, LSD and psilocybin have found another method for measuring these states in the brain beyond what is recorded on an EEG. These look at the spontaneous complexity of activity in the brain as a marker for the degree of expanded consciousness.

Studies have shown a significant difference in the spontaneous activation of neurons in the brain when people are awake verses when they are asleep or sedated.  When people are under the influence of psychedelic substances, diverse spontaneous neural activity is even higher than the normal waking state. So people, are “more awake” than usual, so to speak.  There are also specific correlations between self-reported “ego-dissolution” and very high diversity of neural signals.

To explore this method of measuring consciousness more deeply and to avoid the inherent complications of the diverse responses of the individual’s body/system to the neuropsychopharmalogical changes in response to ingesting psychedelic substances, Dr. Schwartzman used this same procedure to measure the spontaneous signal diversity in people while they were experiencing flickering light from the Lucia N°03 (a “non-pharmacological” altered state). While experiencing both 3 Hz and 10 Hz of flickering light, spontaneous EEG signal diversity scores were significantly higher than during wakeful rest…“a similar pattern of results to those found with psychedelic compounds (LSD, psilocybin and ketamine).” (44).


What Did You See? Perception and the Visual Experience

Past studies on visual perception under flickering light have found closed-eye visuals to be geometric in nature and specifically related to the frequency of the flicker rate. However for those who have tried the Lucia N°03 light experience on multiple occasions, visuals are not limited to geometry. While certain patterns do arise regularly, there are also accounts of bright and variant colors, complex visuals, dream-like scenes, memories, or even other worlds and visitations by beings like deceased loved ones or spirit guides.  

Dr. Schwartzman and his team, for the sake of simplicity and timing, only shared the Lucia N°03 light experience to volunteers at 3 Hz and 10 Hz for 10 minutes each. Even with these shorter sessions, at 3 Hz,  12 out of 19 participants described witnessing complex visual hallucinations (CVH) such as faces or realistic scenes. These reports exceeded the expectations of the researchers, and on a physiological level correlated to higher spontaneous EEG diversity scores and a reduction in the alpha brain-wave power.  If you recall, this demonstrates both greater coherency in the brain and more awakened states. The 10 minute 10 Hz experience was also reported to be very visual with reports by volunteers were centered on colors and geometric patterns.

Tell Me More: Anecdotal Self-Reports

The third way in which the Lucia N°03’s flickering light was compared to data on a psilocybin experience was through self-reported intensity and an adapted questionnaire on aspects of perception of an altered state of consciousness. 
The diagram above, which can be found on page 23 of the study, shows the differences in self-rated measures such as intensity, past, peace, merge, etc. Interestingly, there are many similarities between the self-reported measures of the psilocybin experience and the experiences with the stroboscopic light of the Lucia N°03.

Over The Rainbow: Support, Critiques and a Call for More Research

While the EEG has been around for decades, finding new neurological markers for expanded states of consciousness is exciting. Understanding the diverse neural activation that occurs during an altered state of consciousness is a way for science to ground some of the theories about how these states alter our reality.

Even more exciting is the idea that these states can be accessed through legal methods such as the experience of stroboscopic light from the Lucia N°03.

However, as with all pioneering studies, there were several limitations. First of all, the length of the two different sessions with the Lucia N°03 were only 10 minutes each. From my own years of anecdotal research offering Lucia N°03 light sessions, I have noticed it can take 20-60 minutes of continuous light for a first-time light traveler to sink deeply into the experience. It would be interesting to replicate this study with two or three times the length of sessions, while also comparing singular frequencies with one of the pre-programmed Lucia N°03 sessions that use a variety of frequencies throughout the session.

As with other studies on altered states of consciousness, these experiences were offered in a clinical or semi-clinical setting in order to maintain a rigor of experimental control.  However, it would be interesting to see how different settings would alter the self-reported experience and takeaways from the light travelers. Timothy Leary famously proclaimed that up to 99% of the LSD experience was dependent on the “set and setting,.” Therefore variations in ambiance, preparation and space-holding of the researcher might drastically change the experience of the light traveler.

Despite these critiques, it is both refreshing and exciting to see scientific studies investigating the different ways to access these states and measure them.  My deepest gratitude and respect go to Dr. Schwartzman and his team at the University of Sussex.

FAQ about the Lucia N°03:

- Where can I experience the Lucia N°03 for myself?

If you are interested in experiencing a Lucia N°03 light session, you can book a session with a local light guide in your area. They can be found here.

- Where can I learn more about the Lucia N°03?

Check out our website – or contact Allison with any questions or comments –

- How often can/should you experience the Lucia N°03? Is this something that could be addictive?

Beyond experiencing an expanded state of consciousness and the correlated potential benefits of: meditative and spiritual experiences, a fresh/broadened perspective on life, etc., the Lucia N°03 is also deeply relaxing for the nervous system. Full sessions are generally 30 minutes – 1 hour and a series of 6+ sessions is recommended to assist in lowering the baseline level of stress and accessing a flow state of consciousness, deepening presence, inner peace and patience.  The initial series of sessions can be experienced from 1-3x a week.

While the Lucia N°03 is a powerful even the first time, further sessions assist in dropping deeper into the experience and receiving more benefits. Recently we have released a “Home Portal” which is a smaller and more portable version of the Lucia N°03 that is designed specifically for personal use. 

The Lucia N°03 is not addictive, however new light aficionados often enjoy immersing in the light experience up to once a day for their first few months of using the lamp.  As restrictive patterns shift, the urge to work with the lamp naturally tapers off to once or twice a week, or even every other week. I have personally been working with the Lucia N°03 for 5 years and my personal preferences have gone through different phases over the years. I have spent up to a few months away from it as well as immersing every day for months at a time. My experience with the Lucia N°03 has moved me out of a state of perpetual trauma and depression to a stable, positive, thriving state where even when life offers challenges, I am able to find peace in my response to them.
