Lupine Betty R LED Lamphead: Double Duty as Photography Light
I run the awesome Lupine Betty R LED light for my night rides on my Moots Vamoots RSL road bike and various Moots mountain bikes.
See also the White Mountains descent at dusk video with dual Betty II lampheads.
For photographers, the powerful beam of the Lupine Betty R can also be used for night-time photography, but is best used with a +10CC magenta filter over the lamphead for excellent color balance (in a portable light).
