Frequently Asked Questions

Q: Does the ESMARTER K91 tactical flashlight come with a battery?

A: No, batteries are not included. The short version uses a 16340 rechargeable battery (approx. 1-hour runtime) and the long version uses an 18650 rechargeable battery (approx. 4-hour runtime). Both can be recharged directly via the built-in USB Type-C port.

Q: Can I use this LED torch in the rain or wet conditions?

A: Yes. The ESMARTER K91 flashlight carries an IPX45 water-resistance rating, making it well-suited for use in rain, mist, and splash-prone outdoor environments. However, it is not designed for full submersion in water.

Q: How do I switch between the lighting modes and zoom settings?

A: A single press of the switch button cycles through High, Medium, and Low brightness modes. Double-click quickly to activate the Strobe flash mode. To adjust the beam, simply rotate the lamp head — twist forward to narrow the beam into a long-range spotlight, or pull back for a wide floodlight spread.

Q: What makes this flashlight brighter than standard LED torches?

A: The K91 uses an XHP-series (P50/XHP70) LED lamp bead, which delivers significantly more output than conventional T6-style LEDs. A single XHP50 bead outperforms four standard T6 bulbs, resulting in 600–1,600 lumens of highly concentrated, long-range light output.
