Narva 87541 Interior Light LED 10 - 30V 178mm

Narva 87541 Interior Light LED 10 - 30V 178mm

Compact cool white LED interior light delivering 19 lux at 2 metres from a slim 178 x 33 x 12mm aluminium housing, with IP66 sealed construction, 0.09A efficient draw at 12V, and 5-year warranty for caravans, camper trailers, trucks, marine vessels, and utility vehicle interior lighting applications on 10–30V systems.

Product Overview

The Narva 87541 is a rigid LED interior light designed for caravans, camper trailers, motorhomes, trucks, marine vessels, and utility vehicle interior applications requiring a compact, durable, and efficient LED light source. Producing 19 lux at 2 metres in a cool white output, the 87541 delivers a practical, evenly spread interior illumination level suited to reading, task lighting, galley illumination, work vehicle cab lighting, and general interior ambient light across a wide range of 12V and 24V DC applications. The robust aluminium housing provides significantly greater durability and thermal performance than plastic-bodied interior strip lights, protecting the LED PCB from impact damage in the vibration-exposed environments of off-road caravans, camper trailers, and work vehicles. IP66 ingress protection confirms the 87541 is fully dust-tight and resistant to powerful water jets, making it equally at home in external utility applications including underbonnet illumination, toolbox lighting, step lighting, and engine bay inspection where moisture and dust exposure would compromise standard interior lights. Longer than the compact 87540-12 at 178mm, the 87541 provides a wider light spread and greater output suitable for illuminating larger interior panels, overhead cab areas, and full-width caravan or motorhome wall sections. At 0.09A at 12V and 0.05A at 24V, the ultra-low current draw supports always-on or extended-duration lighting without meaningful battery drain, and the 10–30V input range covers the full span of 12V and 24V DC vehicle and vessel electrical systems without requiring separate voltage variants. Narva's 5-year warranty provides long-term confidence for automotive, marine, and caravan installations.

Features & Benefits

19 Lux at 2 Metres Output: Delivers a measured 19 lux at 2 metres, providing practical interior illumination for reading, task lighting, galley and kitchen areas, cab lighting, and general ambient interior use across caravans, trucks, and marine cabin applications.

Cool White Light Output: Cool white colour temperature produces a crisp, bright light output that maximises perceived brightness and visibility for task-oriented interior lighting in caravans, motorhomes, work vehicle cabs, and utility compartments.

Robust Aluminium Housing: The aluminium body provides superior impact resistance, structural rigidity, and thermal performance compared to plastic-bodied interior strip alternatives, protecting the LED PCB in vibration-exposed off-road, truck, and marine environments.

IP66 Ingress Protection: Fully dust-tight and protected against powerful water jets from any direction, extending the 87541's suitability beyond interior use to external utility applications including underbonnet, toolbox, step, and exterior courtesy lighting in moisture-exposed environments.

Ultra-Low Current Draw: Drawing just 0.09A at 12V and 0.05A at 24V, the 87541 places minimal load on the vehicle or vessel electrical system, making it suitable for always-on or extended-duration lighting applications without significant battery drain.

178 x 33 x 12mm Slim Profile: The slim, low-profile body installs neatly onto interior panels, overhead mounting surfaces, and cabinet undersides without intrusive protrusion, maintaining a clean interior aesthetic in caravans, motorhomes, and marine cabins.

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

Primary applications include caravan and motorhome interior panel and overhead lighting, camper trailer and rooftop tent interior lighting, truck and commercial vehicle cab interior lighting, marine cabin and courtesy lighting, toolbox and storage compartment illumination, 4WD and dual-cab ute interior lighting, step and entry lighting, and underbonnet or engine bay inspection lighting.

Pairs well with the Narva 87540-12 compact 114mm LED strip light for smaller spaces and accent lighting, additional 87541 units for multi-zone interior lighting setups, Narva interior light switches and dimmers for lighting control, in-line fuse holders and wiring accessories for auxiliary circuit protection, and surface-mount brackets and adhesive mounting tape for flexible installation options.

Frequently Asked Questions

How does the 87541 compare to the Narva 87540-12 compact strip light?

Both lights share the same IP66 rating, aluminium housing, rigid format, current draw specifications, and 5-year warranty. The 87541 is the longer 178mm variant with a confirmed 19 lux at 2m output measurement and a 10–30V input range, while the 87540-12 is the compact 114mm variant at 12V. The 87541 is the better choice for larger interior panels, overhead cab lighting, and full-width caravan wall sections, while the 87540-12 suits smaller spaces and applications where the shorter length is a better fit.

What does 19 lux at 2 metres mean in practical terms?

Lux is a measurement of illuminance — the amount of light falling on a surface per unit area. 19 lux at 2 metres means the 87541 produces 19 lux of illumination on a surface positioned 2 metres below or away from the light. For reference, a well-lit office environment is typically around 300–500 lux at desk height, while a comfortable reading level is generally around 100–200 lux. At 19 lux the 87541 provides a useful ambient and task light level for interior spaces such as caravan sleeping areas, cab overheads, and storage compartments, and can be supplemented with additional units for higher-output requirements.

What does IP66 mean and is the 87541 suitable for wet or outdoor applications?

IP66 certifies the 87541 is fully dust-tight and protected against powerful water jets directed from any angle. This makes 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 such as underwater lighting or fully submerged installations, an IP67 or IP68 rated product is required.

Can multiple 87541 units be run from a single switch circuit?

Yes. At 0.09A per unit at 12V, multiple 87541 lights can be connected in parallel on a single switch circuit with minimal total current draw. For example, four units draw just 0.36A total at 12V, well within the capacity of a standard automotive switch and light-duty wiring. For larger multi-unit installations, ensure wiring and fusing are appropriately sized for the total connected load and consider a relay for switch circuits controlling more than 10 units.

What mounting options are available for the 87541?

The rigid aluminium body is suited to direct surface mounting using small self-tapping screws through the housing ends 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 is recommended to ensure the unit remains secure under road vibration and vessel movement. Confirm the mounting surface material and accessibility before selecting the installation method.
