LIGHT is a clinical-grade body scanner designed for home use. It measures what happens inside your body in a 30-second scan. Visceral fat, metabolic age, muscle health, inflammation, and 100+ other biomarkers become visible in seconds.

Until now, this level of internal insight required hospital equipment: DEXA scanners, imaging machines, and specialist appointments. LIGHT brings that capability into your home, delivering personalized health intelligence based on your actual biology, not estimates based on your weight or appearance.

Smart scales send a single electrical signal through the body and use population averages to estimate body composition. They have no visibility into how tissues are actually distributed internally, and cannot distinguish between visceral fat and subcutaneous fat or detect ectopic fat around organs.

LIGHT uses Deep Signal Imaging, a proprietary technology that generates multiple structured signal pathways through the body at different frequencies and angles. This creates a spatial model of internal tissue distribution that captures detail no consumer scale can reach.

LIGHT is designed for anyone who wants to understand what is actually happening inside their body. Whether your goal is losing fat, building muscle, improving your metabolic health, or simply knowing your body is aging well on the inside, LIGHT gives you the data to act on.

The scale tells you your weight. It does not tell you how much of that weight is visceral fat pressing against your organs, how much is muscle you are losing without realizing it, or whether your metabolism is functioning the way it should. LIGHT does.

An estimated 4 in 5 adults have some degree of metabolic dysfunction, and most have no idea. Visceral fat, ectopic fat, and early metabolic risk factors develop silently, often in people with a normal BMI and no obvious symptoms. Standard checkups do not measure them and the scale does not show them.

Losing fat and building muscle are also not the same as losing weight. The scale can stay exactly the same while your body composition improves significantly, or deteriorates. Without internal data, you cannot tell the difference. LIGHT makes that visible, so you know whether what you are doing is actually working.

One in three LIGHT users discovers an early risk factor for type 2 diabetes or another form of metabolic dysfunction they were not aware of. Catching these patterns early is when they are easiest to reverse.

Deep Signal Imaging is the proprietary technology that powers LIGHT. It works by generating multiple independent electrical signal pathways through the body at different frequencies and angles. Different tissue types — muscle, visceral fat, subcutaneous fat, ectopic fat, and organs — each interact with these signals in distinct ways. By analyzing how signals travel across different regions and depths, LIGHT builds a spatial model of how tissues are distributed inside your body.

This approach gives LIGHT a level of internal detail that consumer health devices have not been able to produce until now.

Standard bioelectrical impedance sends one signal along one pathway and measures how much resistance it encounters. The result is a single number that gets plugged into a population-based formula. What comes out is a statistical estimate, not a measurement of your body specifically. This applies to smart scales and most consumer body composition devices on the market today, regardless of how they are marketed.

Deep Signal Imaging generates multiple signal pathways across different angles and depths. This allows LIGHT to capture how tissues are distributed regionally, how deep fat sits relative to muscle and organs, and how internal composition varies across different parts of the body. The output is a model built from your actual signal data, not an average pulled from a reference population.

LIGHT AI is the proprietary analysis layer that sits on top of Deep Signal Imaging. Where Deep Signal Imaging captures spatial signal data from the body, LIGHT AI turns that signal data into validated biomarker outputs and trend analysis.

It was developed in collaboration with researchers from the Norwegian University of Science and Technology (NTNU) and trained on more than 12,000 hospital-grade body scans, including DEXA, MRI, and CT data. By learning from clinical imaging at that scale, the AI recognizes internal tissue patterns and understands how different fat distributions and body compositions relate to long-term health outcomes.

When you scan with LIGHT, the AI analyzes thousands of data points from your result and compares them against what it has learned from clinical data. As you build a scan history, it tracks how your body is changing and refines its understanding of your specific biology.

LIGHT has been independently validated by NAMSA MedTech, demonstrating 98% agreement with clinical DEXA scans on key body composition markers including body fat, muscle mass, and fat distribution. Third-party validation means the accuracy claim is not self-reported. An external organization with no stake in the outcome ran the testing and confirmed the results.

A DEXA scan is the clinical gold standard for body composition measurement. It uses low-dose X-ray beams at two different energy levels to differentiate between bone, lean tissue, and fat across the entire body. The results are highly detailed and regionally specific, which is why DEXA is the benchmark that body composition research and clinical practice is built around.

LIGHT was validated directly against DEXA by NAMSA MedTech, achieving 98% agreement on key markers including total body fat, muscle mass, and regional fat distribution.

A clinical DEXA scan requires a hospital or specialist clinic, costs several hundred dollars per session, and typically takes weeks to book. LIGHT delivers comparable accuracy at home in 30 seconds. A single DEXA scan gives you one data point. Scanning regularly with LIGHT gives you a continuous picture of how your body is actually changing.

LIGHT is a health and wellness device, not a diagnostic tool, and it does not diagnose disease. What it does is measure and track internal biomarkers that are associated with metabolic risk, including visceral fat levels, insulin sensitivity trends, early type 2 diabetes risk, and sarcopenia risk, among others.

These patterns can surface early warning signals that are worth discussing with a doctor. LIGHT does not tell you that you have a condition. It tells you that something inside your body may be worth paying closer attention to.

LIGHT tracks 100+ biomarkers covering body composition, fat distribution, muscle health, metabolic function, cardiovascular health, hydration, and biological aging. The most clinically significant include visceral fat, ectopic fat, liver fat probability, muscle mass, muscle distribution, metabolic age, insulin sensitivity trend, inflammation load, sarcopenia risk, cardiovascular risk trend, early type 2 diabetes risk, hydration levels, and pace of aging.

Together these biomarkers give you a detailed picture of what is happening inside your body, and how your lifestyle is affecting it over time.

Visceral fat is fat stored deep inside the abdominal cavity, packed around your organs. It is different from subcutaneous fat, the fat you can pinch under the skin, and it behaves differently in the body. Visceral fat is metabolically active. It releases inflammatory compounds, disrupts insulin signalling, and raises the risk of type 2 diabetes, cardiovascular disease, and metabolic dysfunction.

The problem is that visceral fat is invisible from the outside. People with a normal weight and a flat stomach can carry dangerous levels of it. The scale gives no indication of how much visceral fat you have. LIGHT measures it directly.

Metabolic age is a measure of how efficiently your body is functioning relative to your chronological age. A metabolic age higher than your actual age indicates that your metabolism is operating below where it should be for someone your age, which is associated with higher risk of metabolic disease, faster biological aging, and reduced physical capacity over time.

Metabolic age is also one of the most responsive biomarkers to lifestyle change. Reducing visceral fat, building muscle, and improving sleep can bring metabolic age down measurably within weeks. Tracking it over time shows you whether what you are doing is actually working at a biological level.

Weight is a poor proxy for what is actually happening inside your body. When you lose weight, you may be losing fat, muscle, water, or some combination of all three. When you gain weight, you may be building muscle while simultaneously losing fat. The scale cannot tell the difference.

Fat loss and muscle gain are the changes that actually improve your health, your appearance, and your long-term metabolic function. Visceral fat reduction specifically lowers your risk of diabetes and cardiovascular disease in ways that general weight loss does not guarantee. LIGHT makes these distinctions visible, so you can see whether your training and nutrition are producing the internal changes that matter, not just a number on a scale.

After each scan, LIGHT's AI analyzes thousands of data points from your result. It identifies which biomarkers are outside a healthy range, how severe the deviation is, and whether related biomarkers are pointing to the same underlying pattern. Elevated visceral fat, high metabolic age, and impaired insulin sensitivity, for example, are not three separate problems. They are one metabolic pattern with one root cause. The AI is trained to recognize these clusters and explain them as a coherent picture rather than a list of unconnected numbers.

LIGHT's recommendations are built around trends, not individual scan results. Internal biomarkers like visceral fat, muscle mass, and metabolic age do not change dramatically from one scan to the next. What matters is the direction they are moving over time, and whether that direction is improving or worsening.

As your scan history builds, LIGHT identifies which patterns are worth your attention and gives specific guidance on what to do about them. If your visceral fat has been climbing over three months, the recommendation addresses that pattern directly, what is likely driving it and what has the fastest impact on reversing it. If your muscle mass is holding steady while your metabolic age is improving, that gets acknowledged too.

Recommendations cover training, nutrition, sleep, and recovery, based on what your internal data shows is actually changing.

LIGHT bases every recommendation on your actual biomarker values, your reference ranges for your age and sex, and how your results compare to your own previous scans. It does not apply population averages to your situation. A visceral fat score that is mildly elevated in one person may be severely elevated in another. A metabolic age of 45 means something different for a 35-year-old than it does for a 50-year-old. LIGHT accounts for these distinctions in every response.

A single scan gives you a baseline. Repeated scans give you something more useful: a picture of direction. Whether your visceral fat is increasing or decreasing, whether your muscle mass is holding or declining, whether your metabolic age is improving or drifting in the wrong direction. These trends are often more informative than any individual result.

Over time, as LIGHT builds a history of your scans, its analysis becomes more specific to your biology. It can identify patterns that only become visible across multiple data points, and flag changes that would be invisible from a single measurement. 86% of LIGHT users reduce their metabolic age by one year or more. That result comes from tracking, not from a single scan.

LIGHT comes with a free companion app for iOS and Android. You step onto the scanner, the app guides you through the 30-second scan, and your results appear directly in the app when the scan is complete. No calibration, no preparation, and no specialist required.

A single scan takes 30 seconds.

Once a week is the recommended frequency for most users. Internal biomarkers change gradually, so daily scanning adds little additional insight. Weekly scanning gives LIGHT enough data points to identify meaningful trends while keeping the process simple enough to stick to.

If you are making a significant lifestyle change, such as starting a new training program or changing your diet, scanning consistently through that period gives you the clearest picture of how your body is responding internally.

LIGHT should not be used by individuals with implanted electronic devices such as pacemakers or defibrillators, as the device uses electrical signals that may interfere with these devices. Pregnant women should consult a doctor before using LIGHT. If you have a serious medical condition or are under active medical supervision, speak with your doctor before use.

LIGHT is a health and wellness device. It does not replace medical care.

LIGHT was founded by Steffen Westlund, a serial entrepreneur with years of experience in health technology. The company has offices in Oslo and San Francisco.

The technology was developed in collaboration with researchers from the Norwegian University of Science and Technology, Norway's largest university and its leading institution for science and technology research, with particular strength in biomedical sciences and medical imaging, and with NAMSA MedTech, one of the world's leading medical device organizations.

LIGHT's medical direction is led by Dr. Nina Evensen, Executive Medical Director. Dr. Evensen completed her medical degree at the Karolinska Institute and conducted research at the Karolinska Institute and Karolinska University Hospital in Stockholm, focusing on how fat distribution, muscle composition, and metabolic function influence long-term health outcomes.

Development has been funded in part by Innovation Norway, the Norwegian government's primary instrument for supporting research-based companies bringing new technology to market.
