Dun-Bri Interior Lights: Low-Profile LED Panel Lights for Vehicle and Professional Interiors

Introduction

Interior lighting plays a critical role in commercial, industrial, and vehicle environments. Beyond basic illumination, the right interior lighting improves visibility, supports safe operation, and contributes to efficiency in everyday use.

Poorly specified interior lights can result in uneven light distribution, glare, premature failure, and unnecessary maintenance.

Dun-Bri interior lights are designed with these challenges in mind, offering dependable LED solutions intended for professional applications where reliability and practicality matter.

Key Technical Features

LED Performance and Efficiency

Dun-Bri panel lights use high-quality Osram LEDs to deliver consistent illumination with low power consumption. The DBG 14 produces 600lm at 10W, while the DBG 26 and DBG 28 provide 1200lm at 15W, supporting strong light output for vehicle cabins and professional interiors.

With operating lifetimes up to 50,000 hours and a wide operating temperature range (-40°C to +65°C), these lights are suited to demanding environments where reliability and reduced maintenance are priorities.

Light Output and Colour Temperature

A 5700–6500K cool white colour temperature helps maintain clear visibility for task-focused use. Combined with a polycarbonate lens, the output is designed to be practical for interiors without creating harsh glare.

Housing and Build Quality

The panel lights use an aluminium housing with a polycarbonate lens and a low-profile 13mm depth. This combination supports durability while helping to minimise protrusion in tight interior spaces.

Mounting Options

All three panel lights are surface-mount designs with two fixing holes and a 200mm fly lead connection. Options include un-switched, switched, and PIR sensor variants, enabling a straightforward match to different use cases.

Vehicle Suitability and Compliance

The panel light range meets ECE R10 requirements, making it suitable for use in vehicle cabin areas where EMC compliance is required.

Installation and Practical Considerations

Dun-Bri interior panel lights are designed for straightforward installation, helping to minimise downtime during both new installations and retrofit projects.

Practical details such as surface mounting (two fixing points) and fly lead connections support efficient fitting, while the low-profile 13mm depth helps when headroom or clearance is limited.

Typical Applications

• Commercial and specialist vehicle interiors (including cabin areas)
• Utility and service compartments
• Caravans, motorhomes and trailers
• Workshops and technical work areas

The emphasis on durability, stable light output and vehicle suitability makes these lights a practical choice for professional environments.
