Hello, Would you recommend this torch with 850nm wavelength for surface skin vein detection, or is the 940nm or the 630nm torch better for this ?

850nm is a non visible wave length, so is no good for vein detection. A wave length of 620nm is ideal for that purpose. Hope this helps.

Do you sell lens replacements? my one is missing from last night exstertion

I don’t know I am customer like you . If it was me , I would just buy another lamp .
