What is the wavelength?

The wavelength of the red light flashlight is : 620nm-625nm.

The wavelength of this red light is not 670nm. It's 620nm-625nm.

Does this light reflect off the tapetum lucidum with any glow (as does white spectrum light)? Thank you in advance.

I don't believe the light reflects, it is a red lens and bulb behind it. It is a very low light and the flashlight stopped working after using it for a short time. Even though not very expensive don't waste your money.
