The Nightstick USB-578XL-BL gives law enforcement and tactical professionals two independent light sources in a single 5.8-inch package. The primary front-facing LED produces 900 lumens on high, while a separate side-mounted floodlight delivers 250 lumens of area illumination for close-range tasks. This dual fuel flashlight runs on its included 7200 mAh lithium-ion battery or two CR123A cells using the included battery carrier, ensuring you maintain operational capability regardless of charging access. We stock this alongside our full selection of tactical duty gear for professionals who demand reliable illumination tools.
Nightstick built the USB-578XL-BL from aircraft-grade 6061-T6 aluminum with a Type III hard anodized finish for corrosion resistance and impact durability. The dual-switch tail cap provides independent control of each light source, allowing operators to activate the flashlight, floodlight, or both simultaneously for 500-lumen combined output. The primary light offers three brightness modes plus strobe, cycling from 900 lumens at 3 hours runtime down to 150 lumens for 22 hours of extended operation. Direct USB charging through a discretely sleeved collar eliminates port covers that fail in the field, with an integrated indicator that transitions from red to green when fully charged. The IP-X7 waterproof rating means submersion to one meter for 30 minutes without failure, and the anti-roll body design keeps the light stationary on angled surfaces.
This flashlight serves patrol officers checking vehicle interiors, mechanics working under dashboards, and security personnel clearing rooms where both throw and flood lighting prove useful. The 2.5-hour runtime in dual-light mode handles most shift requirements, while the CR123A backup option provides peace of mind during extended operations or when charging infrastructure is unavailable. Every unit ships with a 2-foot USB charging cable, lithium-ion battery, CR123 battery carrier, and Cordura holster. Pair it with a compatible tactical holster from our inventory for secure belt carry.
Yes, the flashlight includes a CR123 battery carrier that accepts two standard CR123A non-rechargeable batteries. This dual fuel capability ensures you maintain light output even when USB charging is unavailable, making it practical for extended field operations or emergency backup situations.
The USB-578XL-BL features two separate tail switches. One switch controls the front-facing primary flashlight with its three brightness modes and strobe function. The other switch operates the side-mounted floodlight independently. You can run either light alone or activate both simultaneously for combined 500-lumen output.
The IP-X7 waterproof rating means the USB-578XL-BL can withstand temporary submersion in water up to one meter deep for 30 minutes. Heavy rain, splashing, and brief drops into puddles or streams will not compromise the light's function or electronics.
A complete charge takes between 3 and 6 hours depending on remaining battery capacity. The built-in charging indicator glows red during charging and switches to green when the 7200 mAh lithium-ion battery reaches full capacity, eliminating guesswork about charge status.
Nightstick includes a 2-foot USB charging cable, the internal lithium-ion battery, a CR123 battery carrier for backup power, a removable snap-on pocket clip, and a Cordura belt holster. The flashlight is ready for immediate use and carry right out of the box.
