Super Bright Led Diving Flashlight】The XHP70 scuba diving light has a 50,000 hour life span and a maximum light output of up to 6,000 lumens, giving you a super bright white light underwater with a range of 328-656 feet. It also comes with 2 x 2000mAh rechargeable batteries to fully charge the unit We charged up each head torch fully then switched them onto their brightest settings to time how long they lasted before they either ran out of battery entirely, or had significantly reduced brightness. We used fresh batteries for non-rechargeable head torches. The more illumination required for your task or activity, the more lumens you should look for in a head torch. However, this also means less battery lifespan between charges or more frequent alkaline battery replacement. Lithium ion (Li-ion) batteries are a handy as they saves both money and the environment. They are also known for having low self-discharge and remain in a stable state when not in use. As many head torches come with rechargeable options via a USB cable, it is easy to recharge via a portable device. Very handy, when out for on a hike or camping trip. Most lithium-ion batteries also have an in-built electronic controller which regulates power and discharge flows eliminating the risk of overheating or exploding.
Reliable & Durable] -- Made of high-grade aluminum alloy, military grade oxidation and anti-wear treatment. With IPX8 waterproof rating, it can be used in a variety of harsh environments. [Note: After each dive, please clean the flashlight with fresh water to prevent corrosion] A head torch is an essential bit of kit for many outdoor activities but it can be a difficult task deciding on the right one for you. Whether you are running, hiking, trail running, exploring in the dark, or camping, this guide will give you a better idea of what works best in different situations. IPX is a rating scale widely used to determine exactly what level of water resistance you can expect a product to have. The higher the IPX rating number, the more resistant to water you can expect it to be. We subjected each head torch to a heavy shower for several minutes and inspected the lamps and battery casings for water ingress.
While we are used to measuring bulbs in watts, this is just a measure of energy usage. It doesn’t directly relate to brightness. With the advent of LED lights, energy usage no longer bears much relation to brightness. Lumens, however, is a measure of brightness and thus much more useful for comparison. How many lumens do I need? Waterproof and Convenient】: Powerful IPX8 waterproof diving ligh available underwater 150 meters. Thanks to Wrist Strap & Lanyard , this flashlight can be adjusted brightness according to the underwater environment by one hand, both above and under water. As shown above, there is a direct relationship between lumens, brightness, weight and battery life. As such while owning the brightest head torch available is great, sometime you just need one that suits your needs and requirements. A head torch with brighter light means more lumens. This value can vary in lumens from between 50 and 2000 lm.
Professional Dive Light] -- Adopts latest XML-T6 led, super bright, the max brightness can be up to 10000 lumens. Especially designed for diving, it can withstand the pressure of underwater 100m, the farthest illuminating distance is 500m, it is a stunning illuminating tool for diving. Wide Applications】A professional underwater lamp, not only for diving, but also for underwater lighting, fishing, diving, swimming, but also for daily life! Ideal for camping, hiking, sailing, hunting, walking, climbing, adventure, exploring, caving, hiking, etc. We set each head torch to its brightest setting and compared how brightly it illuminated a specific spot at set distances of 5m, 10m, 25m, 50m, and 75m.To our mind, it should then have as few other features as possible. Just ask yourself, do you really need that multicoloured coloured strobe option? What are lumens? What usually happens though is – as the capacity of the head torch battery reduces, the advertised lumens drops. The brightness of a head torch is measured in lumens. In simple terms, lumen indicates how bright the bulb in a head torch is.
