Best Cordless Work Light for Truck Bed (2026): 4 Lights Compared

Compare the picks

Light details as published on each listing, collected 21 October 2026.

How we scored them

The Shop Score weighs performance, build, value, safety and warranty. Performance is useful light in the bed: output where it counts, a mount that holds on steel, and a head that aims. Safety credits the stated protection ratings, IP68 claimed on the LETOUR puck and IP54 on the Wtoolfex. Only one listing states a warranty term. Lumen claims in this category run ahead of measurement, so the scores lean on format and battery as much as on the headline figure. How we pick explains the weights.

Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.

What the listings tell you

Read the lumen figures as a ranking, not as physics. The LETOUR bar’s own listing disagrees with itself, 8000 lumens in its title against a 6000 lumen maximum in its spec table, and the puck’s 5000 and the bar claims of its rivals come with no table at all. The DEWALT’s 1,700 lumens is the one figure here from a maker whose ratings are usually conservative, and it lights an engine bay adequately, which should calibrate how much of the bigger numbers to bank on. Battery figures are firmer ground: 7500mAh in the bar, 5200mAh in the Wtoolfex, a runtime claim of 24 hours on the puck, and a bare-tool platform on the DEWALT, where runtime is whatever battery you click in.

Mounting is the second thing the listings tell you plainly. Magnets need steel: a modern aluminium bed gives them nothing to hold, which is why the LETOUR bar includes adhesive metal discs, and why the DEWALT’s padded hooks, which grip any hood or bed side from 51 to 74 inches, remain the universal fit. Hooks also hang a light overhead, pointing down into the bed, which no magnet on a vertical wall can do.

Colour and mode are the third thing, and only one listing plays there: the LETOUR puck’s four modes include a steady red, which preserves night vision and draws fewer insects, and a red SOS for the roadside. The other three are white-light tools with brightness levels. For a bed used for camping and night loading, that red mode is a genuine difference; for a work bed, it is a footnote, and the scores treat it that way.

Working in the bed: three jobs

Loading after dark is the common job, and it is a shadows problem: the load itself blocks a light mounted at one end. A puck that moves with you, stuck to the bed wall at the point of work, beats a fixed bar here, and its rotating head keeps the beam off your own eyes. The bar answers the second job, unloading and sorting a full bed, by washing the whole space at once from one mounting, which is why its battery is the biggest here and its display tells you what is left before you start.

The third job is the roadside one: a wheel change or a strap repair on a dark shoulder. That job wants the light off the truck and on the ground or the fender, wants a red mode that does not blind traffic or destroy your night vision, and wants an SOS if the shoulder is a bad one. Only the LETOUR puck lists those modes. The DEWALT answers a fourth job instead, the engine bay that made the truck stop, where its hooks span the hood and its platform batteries swap in seconds. Read the four as a kit list for different nights, and the scores follow the bed jobs first, because that is the keyword’s question.

Buying guide: the best cordless work light for truck bed work

Put the light where the work is

Loading and strapping happen at the tailgate; sorting and repairs happen along the bed walls; engine work happens at the front. A rotating magnetic puck covers the first two by moving with you. A fixed bar covers the whole bed at once and stays there. The hood light covers the engine. Decide which of those is your usual job before choosing, because the formats do not substitute for each other: a bar cannot follow you to a wheel arch, and a puck cannot wash a whole bed from one spot, whatever its lumen claim says. Our magnetic vs hook work light comparison stays on that mounting question.

Charging is part of the kit

Two of the built-in lights charge by USB-C, the Wtoolfex by Type-C explicitly, which means the same cable as a modern phone and a charge from the truck’s own USB port between jobs. The puck and the bar carry their batteries inside, so their runtime is fixed by their cells, 7500mAh in the bar’s case. A light that lives in the truck should be charged where it lives; a light that has to come indoors to charge will be indoors on the night it is needed. The DEWALT avoids the question by using the batteries already on the truck’s shelf.

Runtime is a battery decision

A built-in battery is simple and finite: when it dies, the light charges or the job stops. The DEWALT’s swappable platform batteries are the professional answer to a long night, at the price of owning into the platform. For occasional bed work, built-in is enough; for nightly work, swappable wins.

Water and dust find work lights

A truck bed is an outdoor place: rain with the cover open, dust on every road, and a light that gets knocked off a wall onto the bed floor. The stated ratings here run from IP54 on the Wtoolfex to a claimed IP68 on the LETOUR puck, with nothing stated on the bar or the DEWALT. A light that lives in the bed should carry some rating and some drop protection, the Wtoolfex’s rubber end caps being the stated example; a light that visits from the garage can live without either.

Frequently Asked Questions

Will a magnet hold on an aluminium truck bed?

No. Magnets need steel. The LETOUR bar includes adhesive metal discs for non-steel surfaces; the DEWALT’s hooks grip regardless of material.

Which light is brightest?

On stated figures, the LETOUR bar, at a 6000 lumen maximum in its spec table, whatever its title claims. The DEWALT’s 1,700 lumens is the most conservative figure here.

Which runs longest?

The LETOUR puck claims 24 hours. The DEWALT runs as long as your platform batteries last, which is the practical answer for long jobs.

Can these lights work under the hood too?

Yes. The Wtoolfex is sold as an under-hood light with hooks, and the DEWALT is a hood light by design. The magnets serve both ends of the truck.
