The Olight M20 Warrior Premium was developed for military and law enforcement users, and it excels for those type of tasks, but it also works great as an outdoor light. The M20 uses lithium batteries, given you a super bright light in a relatively small package. The packaging contains the light, a killer sheath, a battery holder, and other standard accessories.

Until I run out of them, the 2009 holiday set has an M20 and an iTP A3 EOS titanium for $100. Considering that the lights separately would cost you $140, the set is a pretty ridiculous deal.
