Frequently Asked Questions
Q
What wavelengths does the Red Light Therapy Sleeping Bag use?
The sleeping bag uses two wavelengths: 660nm (visible red light) and 850nm (near-infrared light). The LEDs are distributed in alternating rows — one row of 660nm red followed by one row of 850nm near-infrared.
Q
Why do the 850nm LEDs appear dim? Are they working?
