| Compact handheld device | Targeted areas and occasional use at home | Red light is commonly offered near 630–660 nm; some devices also include near-infrared light. | Place or hold it at the distance specified in the device instructions. Treat only the intended area. | Avoid staring into the LEDs. Use eye protection when directed by the manufacturer, especially when treating near the face. | Switch off and unplug before cleaning. Wipe the surface with a soft, dry or lightly damp cloth; do not immerse. |
| Flexible light wrap | Convenient application to a limited body area | Often uses red light, near-infrared light, or a combination; wavelength and output vary by model. | Secure it comfortably without tight compression. Follow the recommended session duration and placement instructions. | Do not use over irritated or damaged skin unless a qualified clinician advises you to. Stop if you experience unusual discomfort. | Disconnect the controller before cleaning. Keep fabric, cables, and connectors dry unless the manual states otherwise. |
| Small tabletop panel | Focused treatment at a desk or bedside | Many panels combine red wavelengths around 630–660 nm with near-infrared wavelengths around 810–850 nm. | Set it on a stable surface and use the distance and exposure time specified for that particular panel. | Keep the panel away from water and flammable materials. Do not assume that brighter-looking light means a more effective dose. | Let the unit cool as instructed. Dust vents and the light surface gently; avoid abrasive cleaners. |
| Medium wall-mounted or stand-mounted panel | Regular treatment of a larger area while standing or seated | Red and near-infrared combinations are common, but exact wavelengths and irradiance are product-specific. | Use the supplied mounting hardware or a stable stand. Check that the panel cannot tip or fall before use. | Protect your eyes as instructed and keep other people and pets from looking directly at the light source. | Inspect mounting points and power cables periodically. Unplug the unit before moving or cleaning it. |
| Large full-body panel | Covering a broad area from a fixed position | Typically offers multiple red and near-infrared LED bands; specifications differ among devices. | Allow clear space around the unit for ventilation. Follow the manual for body position, distance, and session length. | Start with the manufacturer’s recommended exposure rather than increasing time on your own. Seek medical advice if you have a photosensitive condition or take photosensitizing medication. | Check the frame, fasteners, and cables for wear. Keep air inlets and outlets unobstructed. |
| Portable rechargeable unit | Travel or use where access to a power outlet is limited | Usually designed for a small treatment area; wavelength, battery capacity, and output depend on the model. | Charge with the supplied or manufacturer-approved charger. Use only on a stable, dry surface. | Do not use a device with a swollen, damaged, or overheating battery. Follow the manual’s charging and storage instructions. | Store away from excessive heat and moisture. Clean the light window gently and inspect the charging port for debris. |
| Multi-position panel with adjustable stand | Users who want to change the treatment angle or position | May provide red light, near-infrared light, or both; confirm the listed wavelengths and output for the specific model. | Lock the stand securely before positioning the panel. Adjust it while switched off to reduce the risk of tipping. | Keep the stand on a level floor and do not exceed its stated load limits. Follow the device’s eye-safety directions. | Check hinges and adjustment locks regularly. Clean with the unit switched off and unplugged. |
