CAT CLASS: HQ-10749

150-500 W Work Light

The 150-500 W work light is the mid-range tripod-mounted illumination standard for interior construction and renovation. This size delivers focused lighting for a single room, stair core, or work face without the excess output, and heat, of larger area lights. It sits between handheld/clamp-mount units (Up to 150 W) and high-output site lighting (500+ W).

Key specifications

Specification	Typical range	What it means
Wattage	150-400 W	Output range defines coverage area and heat generation.
Mounting	Tripod (adjustable height)	Standard tripod base positions the fixture 3-7 ft above grade.
Lamp Type	LED or halogen	LED units run cooler and draw less current; halogen offers higher CRI.
Beam Pattern	Focused flood	Designed to light a defined area rather than an entire job site.

How to choose

The 150-500 W band suits interior work where a single fixture lights a room or a specific task area: framing, drywall, electrical rough-in, or finishes in a defined space. For confined areas, tool-mounted tasks, or when multiple small fixtures are preferred, the Up to 150 W Work Light offers better maneuverability and lower circuit load. For open floors, perimeter work, or when one fixture must cover multiple rooms or exterior faces, the 500+ W Work Light provides the necessary throw and area coverage.

What this size handles

Lighting a 12×15 ft interior room during drywall or painting
Illuminating a stair core or elevator shaft for concrete pours
Focused lighting on a wall or ceiling for finish carpentry
Task lighting for plumbing or HVAC rough-in in a single bay
General illumination in a basement or windowless restroom during fit-out
Supplemental lighting for electrical panel installation

Safety & operation

Tripod must be fully extended and locked on level surface to prevent tip-over
Halogen lamps generate significant surface heat; maintain clearance from combustibles and plastic sheeting
Allow halogen fixtures to cool 5-10 minutes before transport or storage to avoid burns
LED units reduce burn risk but still require stable footing to prevent falls if struck

Transport & logistics

Tripod and fixture head typically collapse to 3-4 ft length for van or pickup bed transport
Total weight including tripod commonly under 30 lb; single-person carry to upper floors via stairs or hoist
Multiple units often stacked in truck bed or gang box for multi-room projects

Power & supply

Standard 120 V, 15 A circuit adequate for one or two units depending on wattage
LED models draw 1.5-3.5 A; halogen models may draw 3-8 A at full power
Extension cord typically 12 AWG for runs over 50 ft to avoid voltage drop

Frequently asked

How much floor area does a 300 W unit typically cover?

A 300 W tripod light at 5-6 ft height provides working illumination for approximately 150-250 sq ft, depending on ceiling height and surface reflectivity.

Can multiple 400 W halogen units share a 15 A circuit?

A single 400 W halogen unit draws approximately 3.3 A at 120 V; two units approach circuit capacity, so a dedicated circuit or LED alternatives are advisable for multi-light setups.

What is the practical difference between LED and halogen in this wattage range?

LED units in this band produce equivalent light output at roughly half the wattage, run cooler, and allow more fixtures per circuit; halogen offers higher color rendering and lower initial cost.
