Need Super Bright Red LED headlamp powered by an 18650

[MidnightDance]

Bought a few on the market but they are too dull. Want to find one I can sell in my business but it needs to be very bright for a red led. Anyone help?:shakehead

Do you have any other requirements (beamshape, multiple power levels, etc)?

Quick question - why bright red? If it's for dark-adapted night vision preservation, you might as well go for bright white - it will be about as useful for that purpose (which is to say NOT useful) and you'll at least be able to see colors too.
If you are using red for dark-adapted vision preservation, you need it to be dim. Around 1 or 2 lumens.
