The SLH-890S Waterproof Heavy Duty Flashlight is a high-power rechargeable tactical flashlight featuring a 50W white light source, eight 18650 lithium batteries, USB/Type-C charging, digital power display, and IP45 protection. Its heavy-duty aluminum alloy housing is suitable for outdoor use, emergency lighting, night patrol, vehicle inspection, and field work. OEM/ODM customization is available.
The Forest Tiger SLH-890S Waterproof Heavy Duty Flashlight is a heavy-duty rechargeable flashlight designed for outdoor activities, emergency lighting, night patrols, field work, vehicle inspection, and other applications that require strong portable illumination. It combines a 50W white light source with a built-in rechargeable battery pack using eight 18650 lithium batteries.
With a large battery capacity, USB and Type-C charging, digital power display, IP45 protection, and an aluminum alloy housing, the SLH-890S is designed for users who need a high-power flashlight with extended operating capability. Its 7.1 × 27.5 cm body and approximately 1150 g net weight provide a more substantial format than compact EDC flashlights while maintaining portability for outdoor and professional use.
50W High-Power White Light for Long-Distance Illumination
The SLH-890S Waterproof Heavy Duty Flashlight uses a 50W high-power white light source with a focused optical system designed to provide concentrated directional illumination. This configuration is suitable for applications where users need to illuminate distant areas, inspect outdoor equipment, or maintain visibility in low-light environments.
The focused beam is useful for night patrols, outdoor exploration, search activities, vehicle inspection, field maintenance, and emergency lighting. Actual illumination distance and beam performance depend on the final optical configuration, battery condition, and operating environment.
Digital Power Display for Battery Monitoring
A built-in digital power display allows users to check the remaining battery level directly on the flashlight. This is particularly useful for emergency kits, night work, outdoor activities, and field operations where access to a charging source may be limited.
Instead of relying only on estimated operating time, users can monitor the available battery level and plan charging or replacement arrangements before extended use.
Large-Capacity Rechargeable Battery Pack
The SLH-890S is equipped with eight built-in 18650 rechargeable lithium batteries. The larger battery configuration is designed to provide extended operating capability for applications that require a high-power flashlight for longer periods.
The specified continuous runtime is approximately 6–10 hours, depending on the selected output level, battery condition, and actual operating environment.
The rechargeable battery system is suitable for outdoor work, emergency backup, night patrol, camping, field inspection, and other applications where repeated use is expected.
USB and Type-C Charging for Flexible Power Supply
The SLH-890S supports USB and Type-C charging, providing flexibility when the flashlight needs to be recharged away from a conventional electrical outlet.
Depending on the final configuration, compatible power sources may include power banks, vehicle chargers, generators, and other suitable USB power equipment. This makes the flashlight practical for road trips, remote work locations, outdoor activities, and emergency preparedness.
IP45 Protection for Outdoor Use
The SLH-890S is specified with an IP45 protection rating. The enclosure provides protection against dust ingress at the specified level and resistance to water projected against the enclosure under applicable test conditions.
This makes the flashlight suitable for outdoor environments involving rain, humidity, water splashing, and dust. IP45 protection does not mean the flashlight is designed for underwater operation or prolonged immersion.
Heavy-Duty Aluminum Alloy Housing
The flashlight uses an aluminum alloy housing designed for durability during regular outdoor and field use. The solid construction helps protect internal components during handling and transportation, while the textured grip provides better control during operation.
The approximately 1150 g net weight gives the SLH-890S a more substantial construction than lightweight pocket flashlights. It is suitable for users who prioritize battery capacity and high-power illumination over ultra-lightweight EDC portability.
Applications of the SLH-890S Tactical Flashlight
Emergency Power Outage Lighting
The high-power light source and rechargeable battery pack make the SLH-890S suitable for household emergency kits, power outages, roadside situations, and temporary lighting requirements.
Outdoor Camping and Hiking
The flashlight can be used for campsite lighting, night walking, trail observation, outdoor preparation, and general illumination during camping and hiking activities.
Security Patrol and Night Work
The concentrated beam and substantial battery capacity make the SLH-890S suitable for security patrols, property inspection, facility checks, and other nighttime work where portable directional lighting is required.
Vehicle and Equipment Inspection
The high-output light can assist technicians and vehicle owners when checking engines, tires, wiring, machinery, tools, and other components in low-light conditions.
Field and Remote-Area Applications
With rechargeable power and flexible USB charging, the SLH-890S can be used in remote work areas, outdoor maintenance, field operations, and other locations where access to fixed lighting is limited.
