Powerful PIR-Controlled Exterior Lighting

The RHL5040P-04 combines the higher output of the 50W HILUME platform with automatic PIR motion detection.

This makes it particularly useful for larger exterior areas where a lower-output security floodlight may not provide sufficient illumination.

Rather than leaving the floodlight illuminated continuously, the PIR can activate the light when movement is detected according to the configured settings.

This provides convenient automatic lighting while helping reduce unnecessary operating time.

Integrated PIR Motion Detection

The integrated passive infrared motion sensor makes the RHL5040P-04 particularly suitable for security and access lighting.

When movement is detected within the configured area, the PIR can activate the floodlight automatically.

This makes it ideal for locations such as:

• Driveway Entrances
• Car Parks
• Garage Approaches
• Building Entrances
• Commercial Yards
• Industrial Units
• Pedestrian Routes
• External Storage Areas

Automatic operation provides both practical convenience and security illumination without requiring users to manually operate the floodlight whenever they enter the area.

Highly Adjustable PIR Sensor

Correct PIR positioning is essential for effective motion-activated lighting.

The PIR fitted to the HILUME provides extensive physical adjustment with 180° tilt and 150° swivel.

This allows the sensor to be aimed towards the required detection area while the floodlight itself is positioned to provide optimum illumination.

This flexibility is particularly useful for installations where people or vehicles approach from a different direction to the area being illuminated.

Adjustable Lux Setting

The PIR includes an adjustable lux threshold from approximately 3 lux to 2000 lux.

This allows the ambient light level at which PIR activation becomes available to be configured according to the installation.

For typical security lighting applications, the sensor can be set so that motion activation is required during darker conditions rather than throughout daylight hours.

The wide adjustment range provides considerable flexibility for different locations and operating requirements.

Adjustable Time Delay

The RHL5040P-04 also provides an adjustable time delay from approximately 10 seconds to 10 minutes.

This determines how long the floodlight remains illuminated following motion detection.

A shorter period may be appropriate for pedestrian pathways, while longer illumination may be preferable for driveways, loading areas, garage entrances and commercial access points.

The combination of adjustable lux and time settings allows PIR operation to be tailored much more closely to the application.

4000K Neutral White Light

The HILUME produces 4000K neutral white illumination, providing a clean and practical light appearance for exterior security and access applications.

4000K is particularly well suited to functional outdoor lighting because it provides clear visibility without the warmer appearance of 3000K lighting or the noticeably cooler tone associated with higher colour temperatures.

This makes the RHL5040P-04 suitable for both residential and professional exterior environments.

High 81lm/W Efficacy

The RHL5040P-04 achieves a specified efficacy of approximately 81 lumens per watt.

This provides strong useful illumination from an efficient integrated LED platform, making the fitting a practical replacement for considerably higher-wattage traditional lighting technologies.

When combined with PIR operation, energy use can be reduced further because the fitting only needs to remain illuminated for the configured period following detection.

LED Replacement for Traditional Floodlights

Robus specifies the RHL5040P-04 as an LED replacement for approximately:

• 80W Metal Halide Floodlights
• 350W Halogen Floodlights

This makes it particularly useful for upgrading older high-wattage security and exterior lighting.

Replacing traditional halogen floodlighting with integrated LED technology can significantly reduce electrical demand while retaining the strong illumination required for larger exterior areas.

Wide 100° Beam Angle

A broad 100° beam angle allows the HILUME to distribute light across a wide area rather than concentrating it into a narrow spotlight-style beam.

This is particularly beneficial for security and general-purpose exterior illumination where coverage is often more important than a highly concentrated beam.

Driveways, yards, car parks, industrial access areas and larger patios can all benefit from this broad light distribution.

Designed for Larger Exterior Areas

As a 50W-class HILUME floodlight, the RHL5040P-04 is particularly well suited to applications requiring greater coverage and illumination than the lower-output models within the range.

This makes it an excellent choice for larger residential properties as well as commercial and light industrial premises.

Potential applications include larger driveways, commercial car parks, workshop exteriors, industrial units and external loading or access areas.

Robust Die-Cast Aluminium Housing

Outdoor floodlights must withstand significantly more demanding environmental conditions than typical indoor luminaires.

The HILUME therefore uses a die-cast aluminium housing, providing a durable enclosure while also assisting with the dissipation of heat generated by the integrated LED components.

Effective thermal management is an important part of reliable LED luminaire design and helps maintain consistent performance during prolonged operation.

Durable Powder-Coated Black Finish

The die-cast aluminium body is protected by a high-quality black powder-coated finish.

The powder coating is electrostatically applied and designed to maintain its appearance despite the demanding conditions associated with long-term exterior installation.

Its understated black finish allows the fitting to integrate neatly with a wide variety of residential, commercial and industrial building exteriors.

IP65 Weather Protection

The IP65 rating makes the RHL5040P-04 suitable for outdoor installation when correctly fitted.

IP65 provides protection against dust ingress and water jets, giving the floodlight the environmental protection required for exposed exterior applications.

This makes it suitable for walls and structures around driveways, car parks, industrial units, garages, patios and commercial premises.

IK05 Impact Resistance

The HILUME incorporates a tempered glass diffuser providing an IK05 impact rating.

This adds mechanical protection to the front of the fitting and contributes to its suitability for residential, commercial and industrial exterior environments.

Tempered Glass Diffuser

The use of tempered glass provides a durable front surface while helping the fitting produce broad, practical illumination.

Combined with the 100° beam angle, the diffuser helps distribute light effectively across the target area.

This makes the HILUME particularly useful for vehicular and pedestrian access areas where broad, consistent illumination is required.

Pre-Drilled Adjustable Mounting Bracket

Robus has designed the HILUME range with straightforward installation in mind.

The fitting features a pre-drilled angled mounting bracket, allowing mounting positions to be marked and drilled before the floodlight is secured.

The bracket provides 180° adjustment, enabling the luminaire to be aimed towards the required area after installation.

This provides excellent flexibility for wall washing, signage, driveways, yards, pathways and general exterior security lighting.

Prewired with 1 Metre Rubber Flex

The RHL5040P-04 comes prewired with 1 metre of rubber flex.

The factory-fitted cable can be terminated into an appropriate external junction box, removing the need to unnecessarily open the floodlight housing during normal installation.

This helps reduce the possibility of compromising the factory-sealed IP protection through on-site cable termination inside the luminaire.

Stainless Steel Screws

The HILUME is supplied complete with stainless steel screws, providing durable components suited to exterior environments.

Together with the die-cast aluminium body, powder-coated finish, IP65 construction and tempered glass diffuser, these details contribute to a robust floodlight designed for demanding outdoor applications.

Wide Operating Temperature Range

The RHL5040P-04 is specified for operation across an ambient temperature range of -20°C to +40°C.

This broad operating range makes it suitable for typical UK seasonal conditions, from cold winter temperatures through to warmer summer weather.

Ideal for Commercial & Industrial Security Lighting

The higher-output RHL5040P-04 is particularly useful where motion-activated lighting is required across larger exterior spaces.

Commercial premises can use the floodlight around entrances, yards, car parks and service areas, while industrial sites can use it for access routes, workshop exteriors and other suitable outdoor locations.

PIR activation helps provide useful illumination when movement is detected without requiring the fitting to operate continuously throughout periods when the area is unoccupied.
