The list author says: "It's a good idea to have all your gear use the same kinds of batteries. This list is for AAs. Includes recommended batteries and ways to recharge them."
"Single AA battery. Variable brightness and flashing/signalling (including SOS) modes on both the white and red beams (the picture shows two flashlights, but both red and white bulbs are built into each flashlight; you use one button to control both)."
"From the Amazon description: "The light shines up to 65 feet at a 35-degree floodlight angle. Additional features include continuous and flashing red light, and the light runs for 40 hours on a single AA battery. A narrow headband reduces packing volume, while still offering long-lasting comfort on your head, and the case weighs only 48 grams with batteries.""
