Narva 87543 Interior Light LED 10 - 30V 500mm

Narva 87543 Interior Light LED 10 - 30V 500mm

Maximum-output cool white LED interior light delivering 66 lux at 2 metres from a slim 500 x 33 x 12mm rigid body, with IP66 sealed construction, 10–30V universal input, and 5-year warranty — the flagship unit in the Narva rigid interior light series, purpose-built for caravans, motorhomes, trucks, marine vessels, and utility vehicle interior lighting applications demanding maximum single-strip coverage and output.

Product Overview

The Narva 87543 is the flagship unit in the Narva rigid LED interior light series, delivering 66 lux at 2 metres from a 500mm body — more than triple the output of the 178mm 87541 and nearly double that of the 306mm 87542. Designed for the largest and most demanding interior lighting applications in the series, the 87543 is the preferred choice when a single strip needs to deliver maximum illumination across a full-length caravan living area, motorhome kitchen bench, truck sleeper cab ceiling, or wide marine saloon without requiring multiple shorter units side by side. At 500mm in length and just 12mm deep, the 87543 spans the majority of standard caravan and motorhome interior widths in a single unit, providing even end-to-end cool white illumination across the full installation space. The 66 lux at 2 metres output places the 87543 firmly in task and ambient lighting territory, delivering a bright interior environment suitable for reading, meal preparation, and detailed work tasks rather than simply providing a low-level presence light. Drawing 0.6A at 12V and 0.3A at 24V, the 87543 remains a low-draw solution relative to its output level compared to equivalent incandescent interior lighting, and the 10–30V input covers both 12V and 24V electrical systems in a single unit. IP66 ingress protection extends suitability to external utility applications beyond interior use, and Narva's 5-year warranty provides long-term confidence for automotive, marine, and caravan installations.

Features & Benefits

66 Lux at 2 Metres Output: The highest light output in the Narva rigid interior light series, delivering 66 lux at 2 metres for bright, task-capable interior illumination across wide living areas, galley benches, sleeper cab ceilings, and full-length marine saloon interiors.

500mm Maximum Coverage Width: The extended 500mm body provides the widest light spread in the Narva rigid interior light series from a single unit, covering full-length caravan living areas, motorhome galley counters, truck sleeper cab overhead panels, and wide marine cabin ceilings without requiring multiple shorter strips.

Cool White Light Output: Cool white colour temperature delivers a crisp, bright light output that maximises perceived brightness and clarity for task-oriented interior lighting across caravans, motorhomes, work vehicle cabs, and marine cabin applications.

IP66 Ingress Protection: Fully dust-tight and protected against powerful water jets from any direction, extending the 87543's suitability beyond interior use to external utility applications including underbonnet, toolbox, step, and exterior courtesy lighting in moisture-exposed environments.

500 x 33 x 12mm Slim Profile: Despite the extended 500mm length, the body remains just 12mm deep, installing neatly on interior panels, overhead mounting surfaces, and cabinet undersides without intrusive protrusion, maintaining a clean interior aesthetic.

10–30V Universal Input: Compatible with both 12V and 24V DC electrical systems in a single unit, covering passenger vehicles, caravans, motorhomes, trucks, heavy equipment, and marine vessels without requiring separate voltage variants.

Rigid Construction: The rigid format maintains consistent LED orientation and mounting alignment on flat surfaces, providing stable, vibration-resistant installation suited to the movement and road vibration experienced by caravans and off-road vehicles.

Narva 5-Year Warranty: Backed by Narva's 5-year warranty, providing long-term confidence for automotive, caravan, marine, and utility vehicle interior lighting applications.

Technical Specs

Compatible With / Goes Well With

The Narva 87543 is suited to any 12V or 24V vehicle, vessel, or caravan requiring maximum-output wide-coverage LED interior or utility lighting from a single strip unit. Primary applications include caravan and motorhome full-length living area and galley overhead lighting, camper trailer and expedition vehicle interior lighting requiring maximum single-strip output, truck and commercial vehicle sleeper cab ceiling lighting, wide marine saloon and cabin lighting, large toolbox and equipment compartment illumination, 4WD canopy and trade vehicle storage area lighting, and underbonnet or engine bay inspection lighting requiring the widest area coverage available in the series.

Pairs well with the Narva 87542 306mm interior light for supplementary zone lighting alongside the 87543 in larger spaces, the Narva 87541 178mm light for accent, reading, or bedhead zones, the Narva 87540-12 114mm compact strip for spot and accent applications, Narva interior light switches and dimmers for multi-zone lighting control, and in-line fuse holders and wiring accessories for auxiliary circuit protection.

Frequently Asked Questions

How does the 87543 compare to the other Narva rigid interior lights in the series?

The Narva rigid interior light series comprises four units scaling in length and output: the 87540-12 at 114mm, the 87541 at 178mm with 19 lux at 2m, the 87542 at 306mm with 38 lux at 2m, and the 87543 at 500mm with 66 lux at 2m. The 87543 delivers the highest output and widest coverage of the series from a single unit, making it the preferred choice for large interior spaces requiring maximum single-strip illumination. All four units share the same IP66 rating, 33 x 12mm cross-section, and 5-year warranty.

What does 66 lux at 2 metres mean in practical terms?

Lux measures the amount of light falling on a surface per unit area. 66 lux at 2 metres is a comfortable and practical interior task lighting level — bright enough for reading, meal preparation, detailed work tasks, and general interior use across caravans, motorhomes, and truck cabs. For comparison, the 87541 delivers 19 lux and the 87542 delivers 38 lux at the same distance, making the 87543 the significantly brighter option for applications where maximum output is a priority. Multiple 87543 units in parallel can further increase total lux output in very large interior spaces.

What does IP66 mean and is the 87543 suitable for wet or outdoor applications?

IP66 certifies the 87543 is fully dust-tight and protected against powerful water jets directed from any angle, making it suitable for external utility applications including underbonnet lighting, step lighting, and exterior courtesy lighting in rain and road spray environments. Note that IP66 does not certify submersion resistance — for applications requiring water immersion protection, an IP67 or IP68 rated product would be required.

Can multiple 87543 units be run from a single switch circuit?

Yes. At 0.6A per unit at 12V, multiple 87543 lights can be connected in parallel on a single switch circuit. Two units draw 1.2A total at 12V, remaining comfortably within the capacity of a standard automotive switch and light-duty wiring. For installations of three or more units, a relay is recommended to protect the switch from sustained current load, and wiring should be appropriately sized and fused for the total connected current draw.

What mounting options are available for the 87543?

The rigid body is suited to direct surface mounting using small self-tapping screws through the housing ends and mid-span onto interior panels, overhead surfaces, and cabinet undersides. Double-sided adhesive tape can be used for light-duty interior applications where drilling is not preferred. For overhead and inverted mounting in caravans and marine cabins, screw mounting at multiple fixing points along the 500mm length is recommended to prevent centre sag and ensure the unit remains secure under road vibration and vessel movement.
