If either of these numbers is replaced with an X, it means that the flashlight either offers no protection or has not been tested. The second number represents the flashlight’s protection from liquids, with 1 indicating something like a vertical rainfall and 8 being full submersion in water, greater than 1 meter, for more than 30 minutes. The first number indicates solids, with 1 being protection from an object greater than 50mm, like a hand, and 6 indicating that the flashlight is fully impenetrable by grit and dust. You’ll see this as IP followed by two numbers. Lastly, most flashlights come with an Ingress Protection (IP) rating, which is a measurement of the level of solids and liquids that can get into the flashlight. Manufacturers often list claimed battery life for different modes, with the lowest setting sometimes lasting for days at a time while high-powered settings just a few hours.Īside from traditional brightness scales, many lights come with strobe or blinking settings which tend to be higher in power usage, but give a unique light fixture that can scare away some wild animals or alert others to your location. Low or eco settings, for example, might suffice for smaller jobs and will extend battery life, while higher modes can drain a battery much quicker. And anything over 5,000 mAh is often used to power stronger lights for hours at a time.Īnother feature to look for in a rechargeable flashlight is whether or not it offers different power modes. The sweet spot for all-day battery life is about 3,000 mAh. Sub-1,000 mAh batteries can be found on our more portable picks and offer a shorter battery life. With this in mind, take into consideration what you’ll use your flashlight for and how often you think you’ll use it before deciding how much battery capacity you think you’ll need.īattery capacity is measured in milliamp hours (mAh), which measure electric power over time. It’s up to you to keep your rechargeable flashlight juiced. Just because your flashlight is rechargeable, and you no longer have to worry about stocking the right-size batteries for emergencies, doesn’t guarantee it’s always charged. To light up large, open environments, like a campsite, we recommend a flashlight with a minimum of 1,000 lumens, as LEDs are brightest when first turned on but can dim as they warm up. If you’ll be focusing your rechargeable flashlight’s beam on a concentrated area, such as under the hood of your car, you won’t need as many lumens as you would if you were lighting up a large work area. Meaning, the light with the most lumens may not case the brightest light. Theoretically, the higher the number of lumens, the stronger the light will be, though factors such as reflector shape and lens determine how far and wide that light is cast. Lumens measure the strength of a bulb’s light, or its overall brightness.

Rechargeable flashlights have longer-lasting batteries and use powerful LED bulbs that produce light output nearly 75 percent stronger than traditional battery-powered incandescent flashlights.Ī good rechargeable flashlight combines the long-standing power of a traditional battery-operated option with the convenience and utility of quick-charging technology. Gone are the days of searching high and low for batteries-which, ironically, usually occurs in the dark. For times when your power goes out unexpectedly, an emergency repair arises after sundown, or a project has you working in hard-to-see spaces, a reliable and readily available flashlight is a must-have.
