Best of 2017: get two ultrabright 500-lumen tactical flashlights for $20

Stay safe this winter and enjoy the great outdoors after dark.

All this week, we are counting down the best deals of 2017 from the PopSci Shop. For the penultimate day, we’re focusing on the UltraBright 500-Lumen Tactical Military Flashlights. These pocket-sized lights have a range of one mile, and are rugged enough for any outdoor adventure—making them a popular buy all year round. Best of all, you can get a two-pack for just $20—and use code BESTOF17 for an extra 17 percent off.

These flashlights weigh just 65 grams, and are 9.4 cm long. But don’t be fooled by these diminutive dimensions. On full power, the UltraBright lights can pierce through the darkness like a handheld sun. You can also adjust the beam and switch to lower power, depending on what you need. For instance, you might want a powerful beam for hiking, but more diffuse light for spelunking.

Made from lightweight aircraft aluminum alloy, these flashlights are well suited to outdoor pursuits. There’s even an SOS mode, should you ever find yourself lost after dark. Thanks to a wide working voltage, you can also expect impressive longevity from a single AA or 14500 battery.

The two-pack is worth $100, but you can grab these flashlights for $20 with a hard carry case included.
