Have the precision control you need on tactical missions with the Acebeam T37! Use the two-stage tail switch for momentary or constant-on activation, essential in high-stakes scenarios. The secondary rotary switch keeps mode cycling easy to access, exactly when you need it. Output the 4000-lumen turbo mode with a simple click and provide light up to 1443ft away, perfect for late-night scouting.
Looking for more tactical functionality? Thanks to the strike bezel, you have excellent glass-breaking capability, so you're ready for any emergency. Not only that, but the instant strobe mode gives rapid access to emergency signaling and self-defense while you're outside the precinct.
Reveal a hidden USB-C port by twisting under the light bezel, allowing for rapid recharging from power banks, wall adapters, and other electronics. Fully charge up in just 2.5 hours and head out of the precinct with up to 72 hours of light on ultra-low mode. This is all thanks to the included lithium-ion 21700 battery, which has a long-lasting 5000mAh capacity to power your adventures for longer!

"This replaced an old Surefire 1000 lumen CR123 battery flashlight. It is superlight, compact and has 4000 lumens. Fits easily in any pocket. How about adding a clip for a hat then you may not need a headlamp. Serious power for under $100. Test drive at night on my road bike illuminated a large area."
"Amazing service, pricing and quick response time to inquiries"
