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
Square LED Work Light
Compact square work lamps for bumper, bar and cage mounting where space is tight and mounting points are fixed.
Product overview
What This Product Is
Square work lights are the workhorse of the auxiliary lighting market. The flat body sits close to the mounting surface, which keeps the lamp out of branch strikes and reduces the leverage that vibration applies to the bracket. Sunlitec builds them in several body sizes so an installer can fill an existing bumper cutout without fabricating a new plate.

Comparison
How It Compares
Square lamps clear obstacles better than round lamps of the same output and suit rectangular factory apertures. Round lamps usually win where the existing hole is round or where the buyer wants a classic look. If the run is longer than about a metre, a light bar is more efficient than a row of separate pods.

Installation And Service Notes
- Check the aperture and bolt pattern before ordering, not after
- Mount on a structural member so the bracket is not loaded in bending
- Aim with the vehicle loaded, since ride height changes the beam throw
- Match colour temperature across a vehicle so the driver’s eyes are not fighting two different whites

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.
FAQ
Square LED Work Light FAQ
What sizes do the square work lights come in?
Several body sizes share the platform. Tell us the aperture or the mounting point you need to fill and we will send the models that fit it.
Spot or flood beam?
Flood for close work around the machine, spot for throw down a track. Most fleets fit both: flood on the sides and rear, spot facing forward.
What is the minimum order quantity?
MOQ depends on whether the order is standard stock or private label with your own branding. Message us on WhatsApp with the model and quantity for a straight answer.
Can you match a lamp we already buy?
Send photos and the mounting dimensions. We build 200+ models across 30+ series, so there is a good chance something already matches your footprint.
