Construction And Engineering Vehicles
Work lighting for excavators, loaders, cranes, engineering vehicles and site plant running long shifts in dust and vibration.
LED Work Lights
Round LED Work Light
Round auxiliary work lamps for vehicles with circular factory apertures and for buyers who want a classic driving lamp silhouette.
Product overview
What This Product Is
Round work lights suit the many machines and vehicles that came from the factory with a circular lamp aperture, and they remain the preferred look on bull bars and roof racks. The circular housing also distributes seal compression evenly around the lens, which is one reason the format has survived so long in heavy equipment.

Round LED Work Light In Detail
Comparison
How It Compares
A round lamp is the right answer when the aperture is round or the styling calls for it. For a flat bumper face with limited depth, the square work light sits closer to the surface. For long range throw on the highway, a driving light with a purpose built reflector will out-perform a work lamp of the same wattage.
Use guide
Installation And Service Notes
- Confirm the aperture diameter and the stud or bracket pattern first
- Torque the mounting stud to the bracket specification so the seal is not distorted
- Keep the lens clear of mud build-up, which traps heat against the lens
- Aim the outer pair wider than the inner pair when fitting four lamps

How To Choose An LED Work Light For Heavy Machinery
Duty cycle, thermal headroom, sealing and beam pattern decide whether a work lamp lasts a season or a shift. Lumens barely enter into it.
IP67 vs IP68 For Vehicle And Marine Lighting
The two ratings are one digit apart and describe very different service conditions. Fitting the wrong one below the waterline is an expensive mistake.
FAQ
Round LED Work Light FAQ
Will this fit the round hole on my machine?
Send the aperture diameter and a photo of the mounting studs. We build several diameters and can tell you quickly whether one is a direct fit.
Are round lamps as bright as square ones?
Output depends on the LED count and drive current, not on the housing shape. Compare the datasheets for the specific models rather than the body format.
Can these be used on a boat?
For deck use above the waterline, ask us about the IP rating of the specific model. For hull or immersed positions use the IP68 marine range instead.
Do you sell mounting brackets separately?
Brackets are supplied with the lamp. Spare and alternative brackets can be quoted with the order.
