When I first got it the switch seem wired it would sometimes work and sometime not. Then one night it got stuck in the on position and would not turn off. I am checking with the company to see if they will replace it. I will keep you posted. ### ⭐⭐⭐⭐⭐ Excellent choice for small but powerful flashlight *by M***G on February 7, 2017* I wanted a very bright and highly dependable flashlight that is relatively small and lightweight. The Nightstick 540XL fit the bill perfectly. It is extremely bright, fits nicely in my hand and pocket. I have purchased other flashlights from this company and like the fact that they are well built and durable. You will like this light. ### ⭐ cheap lights *by B***E on November 27, 2014* Light is bright but the switch is problematic. The light turns on and off on its own. Stick with the proven brands such as surefire and streamlight. I've bought $20 lights that are all more reliable than this one. ## Frequently Bought Together - Nightstick TAC-540XL Xtreme Lumens Metal Multi-Function Tactical Flashlight-Non-Rechargeable, Batteries Included, 6.25-Inch, Black - Nightstick 560-BATT Rechargeable Li-ion Battery XL Tactical Flashlights, Green --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/10648418-tac-540xl-xtreme-lumens-metal-multi-function-tactical-flashlight-non](https://www.desertcart.co.uk/products/10648418-tac-540xl-xtreme-lumens-metal-multi-function-tactical-flashlight-non) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-20*
