Why do you recommend using the red light therapy device at a distance of 4–6 inches?
While direct skin contact can reduce light loss and increase irradiance for deeper tissue penetration, we recommend using the device at a distance of 4–6 inches (10–15 cm) to achieve the best balance of effectiveness, safety, and comfort:
✅ Avoids overheating:
High-powered panels generate warmth during operation; maintaining a small distance ensures skin comfort and prevents the risk of thermal stress.
✅ Wider treatment area:
A slight distance allows the light to disperse more evenly across larger body regions such as the back, shoulders, or legs, improving overall coverage.
✅ Optimized irradiance:
Our panels deliver 170-212 mW/cm² even at 6 inches, which research shows is an effective range for stimulating mitochondrial activity, promoting cell repair, reducing inflammation, and easing pain.
✅ Low EMF design:
iLUXRED panels feature advanced Low-EMF shielding, ensuring safe use even in close proximity.
✅ Clinical alignment:
Many published studies on photobiomodulation recommend treatment distances between 4–12 inches for consistent therapeutic dosing, which aligns with our recommendation.
👉 For small, localized areas of discomfort (e.g., joints or specific muscles), short periods of closer or even light skin-contact use are possible. However, for regular sessions and whole-body treatments, maintaining a 4–6 inch distance provides the most reliable and safe therapeutic outcome.
