Auxbeam 5D Series 50″ Curved LED Light Bar

Auxbeam 5D Series 50″ Curved LED Light Bar – 288W 28,800LM Combo Beam

If you’re after proper usable light rather than just something that looks good on the roof, this 50″ Auxbeam 5D curved light bar delivers exactly that.

Using Auxbeam’s 5D optic system, it combines dual reflector cups with projector lenses to throw light further down the road while still filling in the near field. The result is a clean, usable beam pattern with no harsh hotspots or dead zones.

The curved design follows the natural line of the vehicle, helping spread light wider across the road or track – ideal for off-road use, lanes and open ground.

Built for Real Visibility

This isn’t just a flood of light – it’s controlled output.

The integrated combo beam combines:

• Spot beam (30°) for long-distance visibility
• Flood beam (60°) for wide peripheral coverage

Together, it gives you a balanced setup that works at speed, off-road and in poor visibility conditions.

Key Features

• 5D optic technology with projector lens and reflector design
• 288W output producing up to 28,800 lumens
• Spot and flood combo beam for distance and spread
• Curved design for improved field of view
• High transmission PC lens for maximum light output
• Durable die-cast aluminium housing
• Adjustable 360° mounting brackets
• IP67 rated for water and dust resistance
• Rated lifespan of approximately 50,000 hours

Built to Handle the Environment

Designed for real-world use, the housing is built from die-cast aluminium with a sealed structure to handle mud, rain and harsh conditions without issue.

Whether it’s mounted to a roof bar, bumper or rack, it’s built to take the kind of use most trucks actually see.

Why We Rate It

There’s a lot of cheap lighting out there that looks the part but doesn’t actually perform. This isn’t that.

The 5D optic setup gives you a proper usable beam pattern, and the build quality is there to back it up. If you want a large light bar that actually improves visibility rather than just adding glare, this is a solid option.
