REI Garage offers the Black Diamond Ion LED Headlamp in several colors (Black pictured) for $5.73. Opt for in-store pickup to avoid the $5.99 shipping fee. That's $6 under our April mention and the lowest price we've seen for any comparable brand-name LED headlamp. (It's the best price we could find by $19.) It features 80 lumens of brightness, red night-vision mode (insanely useful for climbing over your tentmates in the night without shining a bright white light into their sleeping faces), and a lockout switch.
