Flextail has introduced the Zero Lantern, a compact 2-in-1 light that combines a flashlight and a lantern in a body weighing just 2 ounces. The device is built for users who want one small tool that can cover both focused illumination and wide-area lighting.
The lighting modes are clearly separated by function. In flashlight mode, the beam comes from the head and uses a very cool white tone, while lantern mode turns the transparent handle at the bottom into a 360-degree light source with a warm 3,000 Kelvin color temperature.
Runtime appears to be the main selling point
Rather than chasing the brightest output, Flextail seems to be prioritizing endurance. The flashlight is rated for at least 5 hours at 200 lumens and up to 15 hours at 50 lumens.
The lantern mode offers a wider range as well, though it does not last quite as long as the flashlight settings. At 300 lumens, it is listed for a minimum of 3 hours, while the 10-lumen setting can reach 35 hours.
An ambient mode is also included, making the flashlight pulse softly, although Flextail has not stated how long that mode will last.
Small form factor with simple controls
The Zero Lantern measures about 2.8 x 1.2 inches, making it easy to pack in a bag or hang from outdoor gear. Brightness for both lighting modes is adjusted with a rotating ring on the head.
Its 2-ounce weight keeps it light enough for hiking or short trips, and Flextail has given it an IPX5 rating for basic protection against splashes. That makes it more suitable for everyday carry and outdoor use than for heavy exposure to water.
Useful as a marker light, too
Flextail also includes a carabiner hook so the light can be attached to a backpack strap, provided the mounting point fits. That gives the Zero Lantern a second role beyond illumination, since it can also serve as a visibility aid in the dark.
The setup is aimed at users who want one compact device for two different lighting needs. The lantern spreads light broadly, while the flashlight provides a more directed beam from the head.
Battery and charging details are still partly unclear
Product images suggest a removable 16340 cylindrical battery with a capacity of around 4 Wh, but Flextail has not confirmed that detail clearly on its official product page.
A promotional video does show a USB-C port on the Zero Lantern body rather than on the battery itself. That indicates charging happens directly on the device, although other technical details remain undisclosed.
The Zero Lantern is currently being sold through Flextail’s official online store for about $37. An Amazon listing is not live yet, but Flextail says it will arrive soon.
