The flashlight can be used for a long time. The core circuit adopts smart constant current chip, which ensures that the light effect is stable, and the usage time is greatly increased. The tail charge/discharge of the flashlight is charging: 5V / 2A discharge: 5V / 2A. Slow flashing of red light below 3.4V indicates insufficient power, and the red light is always on below 3V, while the light is off below 2.8V. If the voltage is above 3.4V, the green light is on. Additionally, the button indicator shows that the voltage battery is within 1 minute of power on. The flashlight also has a temperature control function that reduces the current automatically if the temperature exceeds 50 degrees. To unlock it, you need to press and hold the power button and shift button at the same time, and the flashlight will be unlocked when the three main lights flash once. When the three main lights flash three times, the flashlight is locked, and the button operation is disabled. To lock the flashlight, you need to press and hold the power button and shift button simultaneously. One of the unique features of this flashlight is the lock function or child lock function. The flashlight has two buttons, with the right button serving as the power button and the left button serving as the shift button. The battery pack is parallel connected and has a capacity of 7800MA/H and a voltage of 3.7V. This flashlight features 3 *SEOUL UV365NM LED high purity UV lamp beads, with a lifespan of 50000 hours, and 3 gear mode. This flashlight is ideal for use in medical, chemical, bioinstrumentation, rock and mineral, fluorescent glowing, and other applications. The LIGHTFE 20000mW Output 365nm UV light Flashlight is a high-power black light UV flashlight that utilizes LG LED sources 3in1 and is equipped with a special filter lens. Price: UV flashlights can range from under $10 to over $100, so consider your budget when choosing a model.īy considering these factors, you can find the best UV flashlight for your mineral collecting needs. Durability: If you plan to take your flashlight on outdoor excursions, it's important to choose one that can withstand the elements and any rough handling it may encounter.ĥ. Look for a model with a long battery life or one that is rechargeable.Ĥ. Battery life: Depending on how often you use your UV flashlight, battery life can be a concern. Intensity: The brightness of the UV light can also affect how well minerals fluoresce, so you'll want a flashlight that is bright enough to make the fluorescence visible.ģ. Shorter wavelengths (around 365 nm) are best for many minerals, but some require longer wavelengths (up to 400 nm).Ģ. ![]() Wavelength: Different minerals fluoresce at different wavelengths of UV light, so it's important to choose a flashlight with the appropriate wavelength for the minerals you're interested in. However, not all UV flashlights are created equal, so here are a few key points to keep in mind when looking for one:ġ. This can make it easier to distinguish between different minerals that may look similar under normal light. ![]() UV, or ultraviolet light, causes certain minerals to fluoresce, which means they emit visible light in response to the UV light. If you're interested in rockhounding or mineral collecting, a UV flashlight can be a handy tool for identifying certain minerals.
