The Nitecore HC33 is an amazing high-performance L-shaped LED headlamp. Powered by a CREE XHP35 HD LED, it blasts out a powerful 1800 lumens, reaching up to 204 yards away. Its multipurpose L-shape design is super flexible. You can take it off the included headband and use it as a handheld flashlight. The magnetic tail cap and removable pocket clip let you mount it hands-free for work or other activities. With a single push-button switch, you can easily control five brightness levels and three special modes (strobe, SOS, beacon) with one hand. To turn it on, just press and hold the power switch. Once on, press to cycle through brightness levels. Double-tap quickly when off to access special modes, and tap repeatedly to cycle through them. It runs on 1x IMR 18650, offering better performance and up to 330 hours of runtime compared to AA batteries. The battery voltage indicator and reverse polarity protection make it perfect for hiking, biking, working, and more. Specifications include a CREE XHP35 HD LED, support for 1x IMR 18650, 1x 18650 or 2x CR123 batteries, a peak beam distance of 204 yds (187m), and more. Features like 'Precision Digital Optics Technology', a 100-degree flood lighting system, and an aero-grade aluminum alloy construction make it a top choice. Package contents are the HC33 headlamp, spare O-ring, spare button cover, pocket clip, headband, holder, user manual, and warranty card.
Using the Nitecore HC33 is easy. First, insert the 1x IMR 18650 battery correctly. Make sure to follow the polarity marks to avoid any damage thanks to the reverse polarity protection. To turn on the headlamp, press and hold the power switch. Once it's on, you can press the switch to go through different brightness levels like Turbo, High, Medium, Low, and Ultralow. If you need special modes like strobe, SOS, or beacon, double-tap the switch when the headlamp is off. Then, keep tapping to cycle through these special modes. You can wear it on your head with the included headband, or use it as a handheld flashlight by removing it from the headband. The magnetic tail cap and pocket clip are great for hands-free use in various situations. When it comes to maintenance, keep the headlamp clean. Wipe it with a soft cloth after use, especially if it gets dirty. Don't expose it to extreme temperatures for a long time as the Advance Temperature Regulation (ATR) technology has its limits. Check the O-ring regularly and replace it if it's worn out. Also, store the headlamp in a dry place when not in use. If you face any issues, refer to the user manual or contact the customer service using the warranty card.
