RedStem RS 1500 is our mid-sized panel offering, perfect for versatile use. It treats your entire body surface area and offers benefits like improved healing, skin rejuvenation, joint/muscle pain reduction, and more. RS 1500 features best-in-class irradiance of 190+ mw/cm2 at 6 inches and 300 LED bulbs, ensuring no gaps in skin treatment coverage and maximizing photon power output. Standard 7 wavelengths in all RS panels to treat from surface level to deep treatment needs. All RS 1500 panels have the ability to interconnect in a series which allows for ease of functionality and offers a larger treatment surface area. At RedStem, we offer only the best. The Sweet Spot Between Portability and Full-Body Coverage The RS 1500 is RedStem's most versatile panel: large enough to treat your back, legs, or whole torso in a single session, yet compact enough to hang from a door, mount to a stand, or move between rooms. With 300 LEDs delivering 190+ mW/cm² irradiance at 6 inches, it treats in minutes what smaller devices take an hour to cover. Seven Wavelengths, One Session Most panels in this price range emit 3–5 wavelengths. Every RS panel delivers 7 — spanning red wavelengths studied for skin, collagen, and surface healing, and near-infrared wavelengths that reach muscle, joint, and deeper tissue. That means one session supports skin rejuvenation, muscle recovery, and joint comfort at the same time, without switching modes or devices. Who the RS 1500 Is For Anyone serious about a consistent light-therapy routine: athletes running daily recovery sessions, people managing chronic joint or muscle discomfort, and anyone targeting skin health from the neck down. If you want true full-body treatment in one standing session, pair two RS 1500s — they interconnect in series — or step up to the RS Max 2400. Frequently Asked Questions How long is a session? 10–20 minutes per area, 3–7 times per week, standing or sitting 6–12 inches from the panel. At 190+ mW/cm², the RS 1500 delivers a therapeutic dose faster than lower-powered panels. What does 190+ mW/cm² irradiance actually mean? Irradiance measures light power reaching your skin. Higher irradiance means shorter sessions for the same dose. Many competing panels measure 100–150 mW/cm² at the same distance — the RS 1500's 190+ reading at 6 inches is among the strongest in its class. Can I expand it later? Yes. RS panels interconnect in series, so you can start with one RS 1500 and add a second later for full-body coverage, sharing one power connection. Stands and mounting hardware are available separately. Is it safe for daily use? Yes. Red and near-infrared light at these wavelengths is non-UV and non-damaging. The most common guidance is simply not to exceed recommended session times, since benefits plateau with overly long doses. Eye protection is included for comfort during close sessions.
