FAQs

How bright is this work lamp?

This lamp has dual brightness modes: High mode delivers 900 lumens for maximum brightness, while Low mode provides 500 lumens for general tasks with extended battery life. The 900-lumen high setting is very bright, suitable for detailed precision work, dark spaces, and professional applications. The 500-lumen low setting is adequate for most general workshop and inspection tasks while conserving battery power.

Is it rechargeable?

Yes, it uses an integrated 3.6V/3.7V lithium-ion 5000mAh battery and is rechargeable. The lamp includes a USB charging cable for convenient charging from any USB power source including computers, wall adapters, power banks, or car USB chargers. Full charge takes approximately 6 hours.

Does it have a clamp?

Yes, this work lamp features an integrated clamp mechanism built into the design. The clamp allows hands-free positioning by securing the lamp to workbench edges, shelves, pipes, ladders, car hoods, and other surfaces. This provides versatile mounting options and directs light exactly where needed while freeing both hands for working.

What is the voltage?

The lamp operates on 3.6V/3.7V from its integrated lithium-ion battery. This low voltage is safe for portable operation and provides sufficient power for the 10W LED to deliver 900 lumens maximum output.

Is it suitable for trade use?

Yes, it is suitable for professional trade and site tasks where portable cordless lighting is needed. The 900-lumen high output, 2.5-4 hour runtime, durable construction, hands-free clamp positioning, and rechargeable lithium-ion battery make it reliable for electricians, mechanics, plumbers, decorators, and other trades requiring focused task lighting in various work environments.

How long does the battery last?

Battery runtime depends on brightness mode: High mode (900 lumens) provides 2.5 hours continuous operation, while Low mode (500 lumens) extends runtime to 4 hours. This is sufficient for typical work sessions. For longer jobs, use Low mode to extend runtime or keep a USB power bank nearby for recharging during breaks.

Does it come with a charger or cable?

Yes, the lamp includes a USB charging cable. You can plug this cable into any standard USB power source including computer USB ports, USB wall adapters (phone chargers), power banks, or car USB chargers. The universal USB charging eliminates need for proprietary chargers and provides maximum charging flexibility.

Can it be used in tight spaces?

Yes, it is specifically designed for portable task lighting in confined areas such as cupboards, lofts, attics, under cabinets, under sinks, engine bays, vehicle undercarriages, and work corners. The compact cordless design, adjustable clamp positioning, and bright focused light make it ideal for accessing and illuminating tight spaces where larger corded work lights cannot reach.

Is it suitable for decorating jobs?

Yes, it is very useful for decorating prep work, painting in low-light areas, snagging checks, detail inspections, and working in cupboards or alcoves. The 900-lumen brightness reveals surface imperfections and true colors. The hands-free clamp positioning allows you to position the light optimally while both hands remain free for painting, filling, or sanding tasks.

Can I use it while charging?

This depends on the specific design - some USB-rechargeable work lights support operation while charging, while others do not. Refer to the user manual included with the lamp. If supported, you can effectively have unlimited runtime by keeping the lamp plugged into a USB power source during use, though this reduces the cordless advantage.

What is the maximum clamp opening?

The maximum clamp opening width is not specified in available information. Typical portable work lamp clamps open to approximately 50-70mm (2-3 inches), sufficient for clamping onto most workbench edges, shelves, pipes, and similar surfaces. Test the clamp on your intended mounting surface to verify compatibility.

Is it waterproof or weatherproof?

The lamp is not specified as waterproof or weatherproof. It should be considered suitable for indoor workshop, garage, and dry site conditions only. Do not expose to rain, moisture, or wet environments. Avoid using in damp locations or during wet weather. For outdoor or wet environment lighting, choose a work light with specific IP rating for water resistance.

Can the battery be replaced?

The 5000mAh lithium-ion battery is integrated into the lamp. Battery replacement is typically not user-serviceable in this type of cordless work lamp. If battery performance degrades significantly after years of use (reduced runtime), the entire lamp may need replacement. Proper battery care (regular recharging, avoiding complete depletion, storage at partial charge) maximizes battery lifespan.

How do I know when it's fully charged?

Most USB-rechargeable work lamps include a charging indicator light (typically LED) that changes color or turns off when fully charged. Refer to the user manual included with the lamp for specific charging indicator behavior. As a general guideline, allow the full 6-hour charging time for complete charge from depleted state.

What can I clamp it to?

The integrated clamp can attach to various surfaces including workbench edges, shelves, cabinet doors, pipes, ladder rungs, car hoods, car doors, toolbox lids, and similar objects within the clamp opening range. The surface should be sturdy enough to support the lamp's weight and withstand clamping pressure. Avoid clamping to delicate surfaces that could be damaged or deformed by clamp pressure.
