LED vs halogen work light: the quick answer

An LED work light wastes less power as heat than a filament bulb, so it runs cooler and lasts longer on a battery. A halogen work light is a filament bulb: most of the power becomes heat, the bulb burns out sooner, and the housing gets hot enough to matter in a tight engine bay. The DEWALT listing puts it plainly from the LED side, claiming low heat output compared to xenon lights and improved run-time from the efficient LED bulb. The Onforu listing claims its LEDs save 80 to 90 percent on electricity. Those claims only make sense against a hotter, shorter-running, thirstier baseline, which is what filament work lights are. For garage work, LED is the buy.

What an LED work light does

An LED work light is a semiconductor light source: efficient, cool-running and long-lived, in a package built for the shop. The listings show the two ends of the range. The DEWALT DCL040 is a cordless 20V MAX light and flashlight putting out 110 lumens, with an integral hook for hands-free placement and a head that rotates 120 degrees. The listing gives 11 to 25 hours of run-time depending on the battery amp hour, and notes the efficient LED bulb is what improves run-time. The Onforu is the fixed-installation end: an 80W, 120V corded flood light 2-pack with 84 LEDs producing 8000 lumens of daylight white, a 120-degree beam covering up to 1150 square feet, and an IP66 waterproof rating for rain, sleet and snow. Between them they cover the hand-carry job and the light-up-the-whole-driveway job.

What a halogen work light does

A halogen work light is the older filament technology: a tungsten filament in halogen gas, the same family as the xenon lights DEWALT’s listing compares against. No halogen light appears in these listings, so there are no halogen figures to compare. What the listings tell you about halogen is indirect but clear: LED makers advertise low heat output, improved run-time and 80 to 90 percent electricity savings precisely because filament bulbs run hot, drain fast and draw hard. In practice that means a halogen work light gets hot in use, needs more frequent bulb changes, and is a poor match for battery power. If you still own one, keep it for quick jobs and mind the heat; for a new purchase, the listings point one way.

The gear: two listed LED work lights, ranked

Both listings are LED, ranked by what each one states it can do.

1. Onforu 80W LED flood light, 2-pack

The area light. Two 80W flood lights, each with 84 LEDs producing 8000 lumens of daylight white at 100 lumens per watt, on 120V corded power with a 4.92 ft cord. The 120-degree beam with reflective film covers up to 1150 square feet, and the matte lens is stated to reduce glare. The die-cast aluminum housing with a fin-type heat sink carries an IP66 waterproof rating, good for rain, sleet and snow, and the bracket mounts to a wall, a crossbeam or a work stand, though the stand is not included. The spec table states a 2-year warranty, the only stated term here. The 9.6 x 1.6 x 6.3 in size is per light. No dusk-to-dawn sensor, motion sensor, switch or remote is included.

2. DEWALT DCL040 20V MAX LED work light

The hand-carry light. A cordless 20V MAX LED work light and flashlight with 110 lumens, an integral hook and a head that rotates 120 degrees. Run-time is 11 to 25 hours depending on the battery amp hour, which is the LED efficiency story in one number. The spec table lists Energy Star, a visual LED bar graph for voltage detection, and a manufacturer warranty type with no term stated. Two caveats from the listing: battery and charger are NOT included, and the water resistance level is stated as not water resistant. Listed at 10.08 ounces and 6 x 3.1 x 12 in.

What the listings tell you

Two LED work lights, two different jobs. The Onforu states the only warranty term here, 2 years, and the only waterproof rating, IP66. The DEWALT states the only cordless runtime figures, 11 to 25 hours, and the only sub-1-lb weight, 10.08 ounces. Brightness spans 110 lumens on the hand-carry light to 8000 lumens per flood light. Neither listing is a halogen, which is itself the market’s verdict.

Pick by the job

Lighting a work area for hours, a driveway, a yard or a garage exterior is the Onforu’s job: corded 120V, 8000 lumens, IP66, mount it and forget it. Close-up work, under-dash wiring, engine bays and anywhere you need light in your hand is the DEWALT’s job: cordless, hooked or aimed with the 120-degree rotating head, 11 to 25 hours per battery. If the job is “which technology,” the answer is LED either way: cooler, longer-running and cheaper to power than any filament work light.

Frequently Asked Questions

Does the DEWALT DCL040 come with a battery?

No. The listing states battery and charger are NOT included. It runs on the DEWALT 20V MAX platform, and run-time is 11 to 25 hours depending on the battery amp hour you pair it with.

How long does the DEWALT DCL040 run?

The listing gives 11 to 25 hours of run-time depending on battery amp hour. The efficient LED bulb is what the listing credits for the run-time, another point for LED over filament work lights.

Is the DEWALT DCL040 waterproof?

No. The spec table states the water resistance level as not water resistant. For wet locations, the Onforu’s IP66 rating is the listing’s answer.

What does IP66 mean on the Onforu flood light?

It is the waterproof rating the listing claims: IP66, with stable performance stated for rain, sleet, snow and other severe weather. The die-cast aluminum housing and fin-type heat sink back the outdoor rating.

Can the Onforu flood light mount on a work stand?

Yes, the listing names three installation methods: wall-mounted, mounted on a crossbeam, or installed on a work stand. Note the work stand is not included.
