Portable lights are invaluable to RVers when hitting the trail, relaxing outside the RV, responding to emergencies and performing maintenance tasks.
Flashlights can do more than just light the way. Thy can also signal an emergency. And if they’re the right strength, shape, size and weight, they also can help with self-defense.
Today’s best flashlights have LED bulbs. LEDs are brighter and whiter than older halogen bulbs and far brighter than even older incandescents. They also are more shock resistant, so dropping one on the trail or while walking to camp facilities at night won’t kill your light.
Many LED flashlights have adjustable light settings. Batteries can last for weeks on a low setting and surprisingly long even on high beam. The bottom line: LEDs emit more light, particularly in groups of three, five or more, but use less energy than a single older bulb.
Influencing your battery choice are your needs, budget and tolerance for the inconvenience of recharging or swapping out single-use batteries.
Most rechargeable flashlights with integrated batteries have lithium-ion units that charge in two to 10 hours. All other factors being equal, the higher the battery’s mAh rating (milliamp hours), the longer it will deliver power before needing to be recharged, and the more draw it can handle. Adding convenience is USB-cord recharging, allowing recharging from other devices, battery packs or vehicle ports.
You can still get flashlights that work on traditional disposable alkaline D cells (the big cylindrical batteries) and AA and AAA cells (smaller cylindrical batteries), or CR123A batteries. Those sizes also are available as rechargeable batteries, usually in nickel metal hydride, or NiMH, so you can buy a charger and recharge reusable batteries hundreds of times. Shop carefully for chargers. Some chargers will replenish four batteries in about an hour or less; others can take four hours or even longer. The Energizer 1-hour charger with 4 NiMH batteries is about $35.
Newer 18650 batteries also are rechargeable, often with 1,800 to 3,000 mAh ratings or higher to power a flashlight longer, and 3.7 volts of power. They power laptops, other electronics and even the Tesla rechargeable car—although a Tesla requires more than 7,000 of them. Seriously! Similar but smaller than the 18650 are 16340 batteries. $10-$25, depending on brand and capacity.
Both sizes can be purchased for a little extra money with built-in protection against overcharging and overheating. You can also buy an overcharge-protected charger. The Dottman Smart Universal Battery Charger can charge AA, AAA, 18650, 16340, CR123 and more sizes and guard against overcharging. About $35.
Let’s look at a few flashlights, and where and when they come in handy.
A tactical flashlight is tough and can take a pounding—or deliver one in self-defense. The Streamlite Stinger slips into a back pocket because it’s thin. Rubber over an aluminum body provides good grip and the polycarbonate lens is unbreakable. It has an adjustable beam and a 50,000-hour LED. It can shine up to 6¾ hours on low, 3½ on medium and 1¾ on high. The strobe can be used to disorient an assailant, or it can signal distress for 5½ hours. It’s water resistant and includes a charger. $100-$125.
The Goodsmann Submersible LED Spotlight Model 9924-H101-01 is versatile and powerful, with an astonishing 1,100-foot beam—more than a third of a football field. Its Cree LED lamp produces a blinding 3,000 lumens. The built-in battery is rated at up to 2,000 mAh, powering it up to 8.5 hours on low and up to 3 hours on high. A flashing emergency beacon has a runtime of up to 7.5 hours. A pistol-style handle makes it easy to hold, and a fold-down stand makes it a work light. It also floats. About $150.
Convenient for hiking, breaking down camp before daybreak or performing maintenance, a headlamp leaves your hands free. The rechargeable Black Diamond series can emit a beam rated at up to 300 lumens, with a low setting available. Runtime on high is up to 30 hours. It’s water resistant, so changing a tire or walking your dog in the rain won’t damage the lamp. $15 and up.
Flashlights with D, AA or AAA cells have been around for decades for one simple reason: They work. They have gone through many iterations. Most significant are the change in lamps from incandescent bubs to halogen and finally LEDs, and tougher cases. With the availability of rechargeable, removable batteries, they’re cheaper to operate. You can’t do much better than a Maglite ML300. It produces 1,000 lumens of light on 4 alkaline D-cell batteries and can run for 97 hours on low or 5¾ on high. Smaller Maglites also are available. $90-100.
Two-hundred hours of use from one charge on a lantern is nothing to blink at, and that’s what the Tough Light Rechargeable Lantern delivers. Lanterns are great for campsites and completing work in dark corners of your RV or at night. Tough Light produces 400 lumens, adjustable to 200 lumens for the longer runtime. A white beacon shines for 265 hours, and a red hazard light for 526. The lantern is water resistant to 5 feet. About $65.
