The Weiita H308 is a powerful and easy-to-use on-head flashlight that's great for DIY work around your house, or outdoor activities like hiking and camping trips. It uses three LEDs for up to 1000-lumen output, including one main CREE XM-L U2 LED bulb, and two CREE XP-E LEDs for dual side lighting. The quality CREE LEDs ensure excellent efficiency and exceptional life of up to 50,000 hours. Four lighting modes, including only main LED on, two side LEDs on, all three LEDs on and strobe with all LEDs on, offer you the power of choice. Two power-packed 18650 Li-ion rechargeable batteries deliver way more runtime than traditional AA battery. With an adjustable head strap, the head lamp sits securely and comfortably on your head, without wobble or wiggle.
