The Neck Rejuvenator is a silicone collar with 49 dual-chip LEDs at 630 and 830 nm, run in 10- or 20-minute sessions. No spectrometer reading exists, so light output is not scored; Kala states 30 mW/cm2. FDA lists it under its maker Shenzhen Kaiyan's registration as a lamp exempt from premarket review, with no 510(k), so it scores 2 on verification, though Kala's page shows an FDA Cleared badge. It covers the neck only, so coverage scores 4. One market-wide reviewer with a Kala code rated it 2.5 of 5, faulting the fixed intensity and wired controller. It is $339.99 on kalaredlight.com, sold as final sale.
