Collingwood launches configurable Tri Bay high-bay range

## Original Article
Collingwood Lighting has introduced its Tri Bay high-bay luminaire range for warehouses, factories, logistics buildings, and other industrial spaces requiring adaptable light distribution.

The range includes selectable optics for contrasting layouts. A 100-degree beam is intended for open areas, while a 30-degree by 90-degree distribution directs light along warehouse racking and narrower aisles.

Lumen output can also be adjusted, allowing one product configuration to serve several mounting heights or illumination requirements. This reduces the number of separate stock-keeping units required by wholesalers, installers, and maintenance teams.

Plug-in control options include passive infrared sensing, microwave sensing, daylight linking, and wireless control. Accessories include wire guards, anti-glare honeycomb mesh, and refractors, enabling the fitting to be adapted for different environments and visual requirements.

Tri Bay has been designed as a compact, lightweight fitting suitable for installation by one person. Its driver can be removed for replacement, reducing the need to discard the complete luminaire where the power supply fails before the LED assembly.

Collingwood gives the fitting a rated life of 100,000 hours to L70. The L70 figure identifies the point at which expected lumen output has declined to 70% of its initial level under defined test conditions. Actual service life will still depend on ambient temperature, switching frequency, contamination, installation, maintenance, and driver performance.

High-bay lighting design extends beyond choosing a wattage. Mounting height, racking position, surface reflectance, task requirements, uniformity, glare, emergency provision, and future changes to the building layout all influence the number and position of luminaires.

A wide beam can provide effective coverage in an open production or storage area, yet may direct excessive light onto the tops of racking. Narrow asymmetric optics can distribute light more effectively along vertical aisles, reducing wasted output and improving illuminance at working level.

Selectable output provides additional flexibility during commissioning. The same fitting can be reduced where measured illuminance exceeds the design requirement or increased where mounting height and surface conditions produce lower results. Settings should be documented so that maintenance or replacement work does not leave neighbouring luminaires operating at inconsistent outputs. Adjustable products still require a formal lighting design, calculation, and commissioning process.

Occupancy controls can reduce energy consumption in intermittently used aisles or storage zones. Microwave sensors may detect movement through some lightweight materials and provide broad coverage, while passive infrared devices respond to changes in thermal radiation within their field of view. Selection depends on mounting height, layout, traffic, temperature, and the likelihood of unwanted operation. Poor positioning can produce nuisance switching, delayed activation, or areas in which movement is not detected reliably.

Daylight linking can reduce output near rooflights or glazed façades, although sensors must be positioned and commissioned to prevent unstable dimming or uneven lighting. Wireless controls can simplify zoning and later reconfiguration, but radio performance, cyber security, access permissions, and long-term support still require attention.

The range arrives as connected lighting, emergency systems, standards, and sustainability become increasingly interdependent. These themes also form the basis of the LIA TECH-X technical programme for the lighting sector.

A replaceable driver can extend installation life where spare parts remain available and the luminaire body, optics, seals, and LED modules remain serviceable. The environmental benefit depends on whether the fitting can be dismantled practically and whether compatible replacement components remain identifiable several years after installation.

Industrial environments expose luminaires to dust, vibration, impact, temperature variation, moisture, and cleaning regimes. Wire guards or other accessories may be required where mechanical damage is possible, while corrosion resistance must be matched to the actual atmosphere.

Emergency-lighting design remains separate from normal occupancy control. Sensor-based switching must not interfere with required emergency operation, and maintained or non-maintained emergency fittings must be tested, recorded, and maintained under the applicable system design.

A five-year luminaire warranty and two-year on-site warranty support the range, subject to Collingwood’s conditions. Specifiers will still need to compare photometric files, control compatibility, environmental ratings, emergency options, installation details, and maintenance requirements against each project.

Tri Bay consolidates optics, output, and control choices within a configurable industrial range. That flexibility can simplify procurement and accommodate building changes, provided each setting is selected and commissioned against measured requirements.
