We use @lighthealth in my practice so patients can see their fat decrease and muscle mass increase, even when their weight stays the same. The way the scanner also prescreens for metabolic dysfunction is groundbreaking.

I just got rid of my smart scale. LIGHT introduces a whole new level of health insight. It’s the only at-home body scanner that can track all three types of body fat and estimate your risk of diabetes, sarcopenia, and other metabolic conditions.

Frequently asked questions

What is LIGHT?

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.

What makes LIGHT different from a smart scale?

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.

How accurate is LIGHT?

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.

How does LIGHT compare to a DEXA scan?

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.

What biomarkers does LIGHT track?

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.

Who is LIGHT designed for?

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.

How do I use LIGHT?

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.

Can LIGHT detect disease?

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.
