The Duo is for those who want both.\u003c\/p\u003e\u003ch3\u003eHow it works\u003c\/h3\u003e\u003cp\u003eThe Neuro 4 uses five strategically placed Vie-LED modules for full transcranial coverage, with the high powered 810nm light reaching across the wider cortex. A specialized intranasal module then sends light through the nasal channel to reach deeper structures the skull would otherwise block. This top and bottom synergy gives a comprehensive brain energy footprint that transcranial only devices cannot match, with the energy geometry focused on the Default Mode Network, the brain's central resting network.\u003c\/p\u003e\u003ch3\u003eWhy 810nm\u003c\/h3\u003e\u003cp\u003eThe Neuro uses 810nm because it offers superior penetration through tissue and bone. Head to head comparison studies at Harvard Medical School and other leading universities point to 810nm for the strongest tissue penetration and mitochondrial interaction, which is why Vielight built its technology around it.\u003c\/p\u003e\u003ch3\u003eIndustry leading power, no heat\u003c\/h3\u003e\u003cp\u003eVielight's patented Vie-LEDs produce among the highest power in the field (around 300 mW\/cm² irradiance, roughly 5000mW total) for effective dosimetry, while the technology is engineered to stay cold, stimulating cells without thermal discomfort. The concave shaped modules are designed to bypass hair for better contact.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eWavelength: 810nm near infrared\u003c\/li\u003e\n\u003cli\u003eTotal power: ~5000mW (max potential), ~1000mW per module\u003c\/li\u003e\n\u003cli\u003eIrradiance: transcranial ~300 mW\/cm², intranasal ~25 to 50 mW\/cm²\u003c\/li\u003e\n\u003cli\u003eEstimated irradiance area: ~400cm² including the intranasal module\u003c\/li\u003e\n\u003cli\u003eSession length: 20 minutes\u003c\/li\u003e\n\u003cli\u003eMedical grade certification: ISO13485 and MDSAP\u003c\/li\u003e\n\u003cli\u003eSafety certification: TÜV Rheinland\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's in the box\u003c\/h3\u003e\u003cp\u003eOne Neuro headset, one intranasal applicator, one charger, one pouch, and one carry case.\u003c\/p\u003e\u003ch3\u003eUsing your Neuro Duo 4\u003c\/h3\u003e\u003cp\u003eEach session is 20 minutes.

Research areas have spanned cognition, neuromodulation, and a range of neurological conditions. We share this as context for how the technology was developed, rather than as a promise of specific outcomes.\u003c\/p\u003e\u003ch3\u003eContraindications and use\u003c\/h3\u003e\u003cp\u003eVielight devices are well tolerated by most people. They are not recommended for anyone with active brain bleeds or a history of seizures. If you are pregnant, consult your healthcare provider before use. Some users notice mild, temporary effects such as a headache, dizziness, or slight discomfort, which generally subside as the body adjusts.\u003c\/p\u003e\u003cp\u003e\u003cem\u003eGeneral wellness device.
