Designed by Dave Asprey
TrueLight makes medical-grade red light therapy panels, designed by Dave Asprey, with four wavelengths and two modes in every LED. Choose the full-body Energy Trism or the targeted Energy Square 2.4. About twenty minutes, two to three times a week.

Designed by Dave Asprey
Dave Asprey, the father of biohacking and 2x New York Times bestselling author, engineered TrueLight around a full four-wavelength system: yellow, red, deep red, and near-infrared, plus steady and pulsing modes, built to the standard he uses himself.

Ordered by the reasons real buyers tell us they bought. Every claim is tied to published research.
Red and deep red are the most studied wavelengths for skin. Smoother texture, firmer tone, softer lines, built with consistency.
Near-infrared reaches the muscle and joint tissue where soreness and stiffness live, calming the signals that drive pain.
Light your worked muscles after training to quiet the soreness and damage that make recovery drag on.
The benefit customers mention first. Unlike screen light, red and near-infrared do not suppress melatonin, so it fits an evening routine.
The same mitochondrial mechanism behind the benefits above, felt as steadier day-to-day energy and cellular support.

How it works
Every TrueLight LED combines four wavelengths in a single bulb, so each session reaches the skin and the tissue below it. No other product combines these four wavelengths plus two modes.
Works at the surface to prep the skin and support recovery. The shallowest of the four wavelengths.
The two red wavelengths most associated with rejuvenation, designed to support skin tone, collagen, and surface tissue.
The deepest wavelength, invisible to the eye. Red and near-infrared penetrate up to 8 to 10mm to reach muscle and joint tissue.
Steady output is designed to ease pain and soreness. Pulsing output is designed to support cellular healing. Switch from the remote.
Unbox, mount or stand, plug into a standard outlet. You are running your first session in minutes.
About 20 minutes per area, held 6 to 8 inches away, 2 to 3 times a week. No more than once per area per day.

FAQ
Plan on about 20 minutes per treatment area, held 6 to 8 inches from bare skin, 2 to 3 times a week. Light therapy rewards consistency, so a routine you can keep beats a marathon. We recommend no more than one treatment per area per day.
Most people use it for skin and anti-aging, pain and inflammation, muscle recovery, sleep, and everyday energy. The research is strongest for skin, wound and tissue repair, and certain kinds of pain, with growing evidence for recovery and sleep routines. It is a multi-benefit habit, not a single-problem fix.
It varies by goal. Recovery, soreness, and sleep are often felt within days to a couple of weeks. Skin changes like tone and fine lines are gradual and show up over weeks to a few months of consistent use. Think of it like brushing your teeth: the routine is what compounds.
The mechanism is well studied. Red and near-infrared light is absorbed by an enzyme in your cells' mitochondria, which researchers believe helps cells produce energy and repair more efficiently. Hundreds of clinical trials exist, with the strongest evidence for skin, tissue repair, and pain. We describe it honestly: promising and well researched, with results that reward consistency.
Visible red light at 630 and 660nm is absorbed near the surface, which is why it dominates the skin research. Near-infrared at 850nm is invisible and reaches deeper, into muscle and joint tissue, up to about 8 to 10mm. TrueLight gives you both, plus 580nm yellow, in every LED, so one session covers surface and depth.
No. Research shows a biphasic dose response: too little light does nothing, the right dose helps, and too much can actually reduce the benefit. TrueLight panels are designed for close-range use, where the light sits inside the intensity range used in clinical studies. Chase consistency and the right wavelengths, not the biggest number on the box.
Every TrueLight LED combines four wavelengths in one bulb. Yellow 580nm preps the skin and supports recovery. Red 630nm and deep red 660nm target rejuvenation nearer the surface. Near-infrared 850nm reaches deeper tissue. Red and near-infrared penetrate up to 8 to 10mm into the body. No other product combines these four wavelengths plus two modes.
Both panels offer two modes you choose from the remote. Steady delivers a continuous burst designed to ease pain and soreness. Pulsing cycles the light to support cellular healing. Pick the one that fits your goal for that session.
Choose the Energy Trism for full-body and larger-area treatment. Its three 12-inch panels give a 36 by 12 inch lit area, then fold down for travel. Choose the compact Energy Square 2.4 for targeted areas like the face, neck, shoulders, joints, and specific muscle groups. Both use the same four-wavelength LEDs, two modes, a built-in 20-minute timer, and the same 1-year warranty.
The panels do not produce damaging UV light, but they are bright. We recommend you do not look directly into the LEDs. It is comfortable to use with your eyes closed, and if the brightness bothers you, wear opaque goggles.
Very little. At direct contact the panel emits about 0.6 milligauss. For reference, a ringing cell phone emits 9 to 15. There are no fans, which keeps the design quiet and helps keep EMF low.
LED light therapy is generally considered low-risk and has nominal contraindications. Some medications can increase light sensitivity, so check labels if that applies to you. If you are pregnant or in cancer treatment, consult your physician first. These products are not intended to diagnose, treat, cure, or prevent any disease.
Both panels are dual voltage and work on any worldwide supply between 80 and 265V, 50/60Hz. They ship with a US plug. The Energy Square 2.4 uses a standard C13 power cord, so no special wiring or adapters are needed.
Free US shipping on orders over $1,000. Most orders ship within 1 business day from our Cleveland, Ohio warehouse and arrive in 3 to 5 business days. Every order is backed by a 60-day money-back guarantee, even on used or opened items, and a 1-year warranty against manufacturing defects. Sale items are non-refundable.
