Can I use regular CR123A batteries if the rechargeable dies?

Yes, the P20iX runs on two CR123A batteries as a backup power source when you cannot recharge the 21700.

Does the guarded tail cap prevent the light from tail-standing?

No, the raised parapets that guard the switch also create a stable base for tail-standing.

How do I activate turbo or strobe without cycling through modes?

Both turbo and strobe have instant activation from off, so you can access them directly without stepping through other brightness levels.

What is the difference between the flood beam and a thrower?

The quad-LED flood spreads light broadly to illuminate a wide area, whereas a thrower focuses the beam into a narrow, longer-distance spot.

Will this fit standard duty belt holsters?

The included NTH20 hard holster is designed to attach to duty belts and MOLLE webbing.

Why it's on GiftsFeed

4000-Lumen Rechargeable Tactical Flashlight with Glass-Breaking Bezel

Most tactical lights put the tail switch right at the base, where every jostle in a holster or backpack risks turning it on and draining the battery. The guarded tail cap here solves that with raised parapets that block accidental presses while still giving you full switch access when you grip the light. It's a small change that makes daily carry practical, and the tail-stand capability it adds means you can use this as a work light when you're not searching or signaling. The quad-LED array spreads 4000 lumens into a flood that lights up everything in front of you rather than drilling a tight spot into the distance, which matters if you're clearing rooms or working in close quarters where a narrow beam leaves you half-blind.

Good gift when

Law enforcement, security, or military personnel
Anyone who needs reliable high-output illumination in the field
Users who want a tactical light that tail-stands without accidental activation
People who carry lights daily and need accidental-press protection

Skip it if The flood beam prioritizes coverage over long-distance throw, so if you need a tightly focused spot for extreme range, a different beam profile will serve you better.

The details

The P20iX delivers 4000 lumens from four LEDs in a compact frame you can carry every day. It throws a wide flood beam out to 241 yards, with enough output to light up a room or search across open ground. The beam pattern favors breadth over distance, so you get useful light where you need it rather than a narrow spotlight.

Six brightness modes span from a 350-hour low to a 30-minute turbo burst. Two programmable user modes let you set preferred outputs for quick access. Instant turbo and instant strobe activate directly from off, so you don't cycle through modes in a hurry.

The steel bezel integrates silicone nitride inlays for breaking glass in an emergency. A built-in USB-C port charges the included intelligent 21700 battery, which manages output efficiency to sustain high lumens without rapid drain. The light also accepts two CR123A batteries as a backup power option when you can't recharge.

The included NTC2i tail cap features raised U-shaped parapets that guard the tail switch from accidental presses while holstered or pocketed. Those same parapets create a stable base for tail-standing the light and provide anchor points for lanyard loops. The hard holster fits duty belts and MOLLE webbing for secure carry.
