A compact new addition has entered the everyday carry flashlight market, reviving a distinctive multi-head layout. Niwalker’s ES01 is a notably short device measuring just 3.5 inches in length and weighing roughly 2.8 ounces. The design is dominated by a wide head assembly approximately 1.5 inches across, making for an unusual profile that prioritizes function over slimness.

A Purpose-Driven Triple Emitter

The triple-lens configuration is not without precedent—Fenix Lighting deployed a comparable structure with its TK45 model back in 2010, then aimed at achieving maximum raw brightness. Niwalker’s interpretation in the ES01 assigns a dedicated role to each optic. One emitter delivers a 6,500K cool white spotlight, a second provides a 4,000K warm white floodlight rated at 90 CRI for accurate color rendering, and the third produces ultraviolet light. When the two visible-light beams are engaged together, the flashlight enters Turbo mode.

Performance and Power Details

The ES01 is powered by a replaceable 14500 cylindrical lithium-ion cell, which shares the physical dimensions of a standard AA battery but operates at a different voltage. Recharging is handled through a USB-C port built into the head. In its combined Turbo mode, output reaches 800 lumens with a maximum beam distance of roughly 984 feet, though runtime is limited to 40 minutes at this setting. Used independently, the cool white spotlight throws up to 880 feet, while the warmer floodlight’s wider beam reduces its reach to approximately 540 feet. Extended operation is possible at lower output levels, and the dedicated UV light can sustain runtime for 3.5 hours.

Availability and Market Position

Priced at around $45, the ES01 has quietly begun appearing through specialist retailers, including Flashlightgo, although Niwalker itself has not yet published the product on its official website. Its combination of a dual-color-temperature primary system, a secondary UV source, and a pocketable form factor positions it as a versatile tool for users who need varied beam profiles in a single carry.
