CAT CLASS: HQ-10749

150-500 w Work Light

The 150-500 w Work Light band comprises mid-wattage portable lighting units designed to illuminate rooms, stair cores, or work faces from tripod stands. This size class sits between handheld and low-wattage units (Up to 150 w Work Light) and high-output area lights (500+ w Work Light), offering broader coverage than portable task lamps while remaining far more maneuverable than balloons or tower lights. Typical units in this range draw 150–400 watts and mount on adjustable tripods for positioning at ceiling or mid-wall height.

Key specifications

Specification	Typical range	What it means
Wattage	150–400 W	Power draw determines light output and coverage area; most units in this band run 300–400 W for room-scale illumination.
Mounting	Adjustable tripod	Tripod stands allow positioning from floor level to 6–8 ft, directing light onto vertical or horizontal work surfaces.
Lamp type	LED or halogen	LED models offer cooler operation and lower draw; halogen units provide high-intensity output with higher heat.

How to choose

The 150-500 w band is appropriate when the work area exceeds handheld reach or requires sustained, hands-free illumination of a room, corridor, or vertical surface. Up to 150 w Work Light is the better choice for close-quarters tasks, toolbox-adjacent areas, or jobs where the light travels frequently with the worker. For large open floors, multi-story atriums, or outdoor lay-down yards requiring broad floodlighting, 500+ w Work Light (or balloon/tower configurations) delivers the necessary coverage and intensity.

What this size handles

Lighting interior rooms during electrical rough-in or drywall finishing
Illuminating stairwells and elevator cores in mid-rise construction
Providing task lighting at masonry or formwork faces on multi-story decks
Temporary lighting for mechanical rooms or below-grade corridors
Site offices, trailers, or staging areas requiring overhead work light
Inspection lighting for concrete pours or finish-coat applications

Safety & operation

Halogen lamps generate significant heat; maintain clearance from combustibles, tarps, and insulation, and allow cool-down before handling or packing.
Tripod legs must be fully extended and locked on stable footing; uneven floors or traffic areas require weighting or tethering to prevent tip-over.
Protect lamps and cords from wet conditions unless the unit is rated for damp or wet locations; GFCI protection is standard on most jobsites.
Adjust tripod height and aim to avoid glare in workers' sight lines; indirect or ceiling-bounce positioning reduces eye strain in enclosed spaces.

Transport & logistics

Tripod-mounted units typically weigh 15–40 lb assembled; one worker carries the head and stand separately or folds the assembly for pickup-bed transport.
Most units fit in service vans or truck beds without dedicated trailers; multiple lights stack for multi-floor distribution.
LED models are lighter and more impact-tolerant than halogen equivalents, reducing breakage during repeated moves between floors or zones.

Power & supply

Standard 120 V AC from temporary power panels, generator circuits, or existing building outlets; 150–400 W loads fit comfortably on shared 15 A or 20 A circuits.
Cord lengths of 25–50 ft are common; extension cords must be rated for the lamp wattage and jobsite conditions (SJTW or equivalent).
LED units draw less current per lumen, allowing more lights per circuit and reducing generator load on off-grid sites.

Frequently asked

How many 300 W LED work lights can run on a single 20 A circuit?

A 20 A, 120 V circuit supplies 2,400 W; allowing for 80% continuous load, approximately six 300 W LED lights (1,800 W total) can operate simultaneously, though actual capacity depends on driver efficiency and startup surge.

What coverage area does a 400 W work light provide from a tripod?

A 400 W LED or halogen unit on a 6 ft tripod typically illuminates 400–800 sq ft to task-lighting levels, depending on ceiling height, reflectivity, and lamp beam angle; tighter beams concentrate light on smaller areas, while wide floods spread coverage.

Are LED and halogen work lights interchangeable in this wattage range?

LED units produce equivalent or greater lumens at lower wattage, run cooler, and draw less current, making them preferable where circuit capacity or heat is a concern; halogen models cost less upfront and deliver high-intensity point-source light for specific tasks.
