A 36-inch half-body panel that covers most of your torso in one position. Nine wavelengths across red and near-infrared, including 660, 810, and 850 nm, with app and on-panel control and a session timer.

The reason to buy a VersoLight is the dosing. Red light follows a biphasic dose-response. Too little does nothing you can measure. The right amount, inside the therapeutic window, is the range the published studies use. Past that window, more light does less, not more. The figure that decides which side you land on is total delivered dose, measured in joules per square centimeter, and it comes down to two things you control: how far you stand, and how long you run.

Most panels are sold on irradiance, a milliwatt number that is easy to inflate with a solar meter and tells you nothing about your dose. We work the other way around. Each VersoLight is measured on a spectrometer, its real output at set distances is published, and every panel ships with a dose guide that turns those numbers into a distance and a time for your goal. You set it once. You are not guessing.

What the panel does

• Covers a half-body area at 36 inches, so a session is one position, not six.
• Runs red and near-infrared together or on their own, set from the app or the panel.
• Ends on a timer, so the session stops where you set it.

What VersoLight adds

• A spectrometer-measured output curve for the panel, published, not a solar-meter rating.
• A dose guide that runs from surface, lower-dose goals to deeper, higher-dose ones.
