What wavelength does your "night vision my wife purchased me years ago" need/use. For best brightest/clearest NV, must use the correct wavelength light. The wrong light can give very poor NV.
Not all Night Vision Devices are compatible with all IR Flashlights, they operate at different wavelengths. Flashlight companies design IR flashlights between 730nm to 1200nm. It is important to find an IR flashlight that is compatible with the wavelength of the NVD that your using.
Find what you need and let us know and i can make a great recommendation on what IR flashlight to get...

Good point! Thank you so much.
I am 99.99999% certain its 850nm
Fenix TK25 IR is a great 850nm wavelength light that imo is one of the best if not the best...
Fenix is a high quality light, using real emiters not clones, with square threads, high quality durable military grade anodizing, and high quality potted drivers. Fenix are absolutely great weapons lights imo, I have many.
TK25IR have been discontinued unfortunately, but just got one discounted last month from
