Turning to the Fenix HM65R-DT FAQ, you can learn more about the product. The headlight was specially designed for trail running and is made of a lightweight magnesium material. The SPORT Headband Fit System allows for quick, one-handed operation, while the widened headband design ensures comfort and stability. The Fenix HM65R-DT uses a Luminus SST40 LED for white light and a SST20 LED for warm white light, both with a lifespan of 50,000 hours. However, Fenix does not currently offer LED replacement services and it is not recommended to replace them yourself, as it may affect product performance and cause damage. The color temperature of white light is approximately 6500K, while warm white light has a temperature color of about 3000K. The HM65R-DT has an operating voltage of 3.6V, an operating current of 4.2A and a rated power of 15W. The headlamp is rechargeable via a USB Type-C port. Full charge takes about 3 hours. It is important to cover the charging connector with the dust cap to ensure the waterproof and dustproof protection of the headlight. To prevent accidental activation of the beacon, it can be locked by holding down either switch for 3 seconds or by pressing both switches simultaneously for 3 seconds. In locked mode, the beacon will flash 4 times to indicate the locked status. To unlock it, simply hold both switches for 3 seconds. When the headlight is unlocked, it will turn on in warm white light mode at low brightness level. The light may derate to a lower level after prolonged use at relatively high emission levels due to intelligent overheating protection. When the temperature of the headlight reaches 60°C or more, the headlight will automatically dim to reduce the temperature. Also, when the voltage level drops below the preset value, the fixture will dim down until it reaches the low output. If your headlight is flashing, flickering, or won't turn on, there could be several reasons. It could be due to a low battery level, dirty contacts between the battery and the headlight, or other problems.
