Petzl Tikka XP2 with Core rechargable battery. High and low white spot light with a beam diffuser for a flood, with a single Red LED for preserving night vision as well as white and red flash/signal mode. As a plus, it re-charges off of a mini-USB port, so all I need to do for a re-charge is hook it up to my Goal-zero solar panel for a few hours. Not that I need to re-charge often, it last a long time. I also have a Petzl Tac-tikka that I really like for using at work and blood trailing, as it has different filters (red/blue/green) that can be used over the full-power white light. The bright blue is great for seeing blood and still preserving most of your night vision.
