Petzl Tactikka Plus Headlamp $25
Gives you the option of using white light or red light by simply flipping a filter in front of the LEDs. The plus version has 4 LED lights instead of 3.
It kicks out more red light than the Tikka Plus 2 with the single red LED. If you're looking for a straight up headlamp in the white light range then I suggest you look elsewhere (MECs got good deals). This tactikka plus is targeted more towards pilots, soldiers, hunters, fishermen or anyone who needs to preserve their nightvision.
I use it around camp a lot because I find I don't blind others with the red filter engaged and I find it easier on the eyes for reading at night.
