The product name says 670nm. But the description in this page says 620nm. What is the real wavelength it operates on?

Hi there, the Revive lamp is 670nm, the 620nm listed is a typo and has been submitted to be fixed. Thanks for letting us know!

is it 670 nm at all three light levels? low medium and high

Thank you for your interest in our products. 670 nm refers to the wavelength. This does not change within the 3 brightness levels of the lamp. The color or hue of light depends on its wavelength, the distance between the peaks of its waves. The brightness of light is related to intensity or the amount of light an object emits or reflects. Brightness depends on light wave amplitude, the height of light waves. I hope this answers your question, but please let us know if you need anything further.

Please also check the photo of the box that was shared by the reviewer named Gnemik. In the box, it says 620nm. Is that also a typo?

Hi again, That was not a typo, but was of the prior version of our lamp.
