Class Leading 10-Year Warranty
PowerBay CMH is built for endurance, delivering consistent lux output with minimal lumen depreciation and backed by a comprehensive 10-year warranty at ambient temperatures up to +50°C. For continuous operation above +50°C, our engineers can assess the application and operating conditions to optimise performance, service life and warranty.
Adaptive Optics
PowerBay CMH’s adaptive optics and rotational arrays allow each fixture to be reconfigured as layouts, racking, or task requirements change, ensuring optimal performance is maintained as site needs evolve over the fitting’s extended service life.
Emergency Power Options
Choose from a 10–30 W auxiliary driver to reduce UPS load, or a DALI-controlled UPS system assigning selected luminaires to an emergency scene. UPS and DALI emergency systems require appropriately protected power and control circuits.
Serviceable Solution
With the driver remotely mounted and protected from ambient temperatures above +35ºC, typical driver replacement occurs at 100,000+ hours, helping optimise system service life to match the LED’s effective L80 lifetime. The LEDs are engineered for higher ambient temperatures; where the driver is exposed to these conditions, refer to the driver de-rating tables or discuss expected service life with our engineers.

Flexible Installation
CMH mounts flush to PIR-insulated panels, with slotted end plates for precise alignment and optional beam or purlin mounts. Side flashings minimise dust accumulation, with custom profiles available to suit the installation.
Remote Driver Flexibility
Drivers can be located up to 300 m from the luminaire, allowing them to operate in cooler conditions or be grouped in an accessible cabinet for easier maintenance, UPS connection and emergency testing. Where local mounting is preferred, an optional driver enclosure provides secure mounting and conduit connection in complex machine areas.

Engineered for Long Term Performance
Ingress and impact:
With food-grade, impact resistant IP66 polycarbonate lenses, solid steel construction, finished in tough epoxy resin, Powerbay protects against impact, wet and freezing temperatures for the long haul.
Thermal Stability
Extruded aluminium heatsinks and high-density LED arrays minimise thermal gain, delivering reliable performance across a wide ambient temperature range.
Vibration and Shock Protection
EPDM dampers and potted drivers protect the fixture against mechanical stress and preserve structural integrity even when exposed to vibration or unintentional impact.
Serviceable Electronics:
IP67 screw terminal connectors protect against moisture ingress and corrosion, while supporting the service and replacement of key components.
Chemical Resistance:
An optional coating to the PCB protects the LED from corrosive gases, moisture and excessive humidity.
Isolated IP66/IP67 LED drivers:
Our isolated drivers are rated Class 1, Division 2 for Hazardous locations and de-rated to 80% of their maximum power output de-stressing components and ensuring optimum service life and reliability.

Narrow Beam Asymmetric Lenses
Whether lighting from extreme height or pushing light down between narrow spaces or aisles, our asymmetric lenses minimise fixture count and ensure optimum uniformity on both vertical and horizontal planes.
Warehouse Image:
PowerBay 5 (HE Chipset 2020) at 14m delivered highly uniform illumination to floor level in a narrow aisle, resulting in measurable reductions in missed picks for the customer, with improved productivity and safer operation.
(Similar results now possible with PB3-PB4)
AS-Lens 45º x 88º
The AS lens increases vertical push and luminaire spacing, suitable for general application including warehouse and high industrial applications at heights between 15-45m.
AC-Lens 33º x 94º
The AC lens intensifies vertical push, while maintaining a wide beam angle (C0/180) to support wider luminaire spacing, reducing installation and product costs.
Rotational LED arrays with optional snap-in reflectors allow each fixture to be configured from narrow to wide beam angles using a standard lens package. This modular optical system enables on-site adjustment, placing light precisely where it is needed.
If aisle layouts change, are removed, or added to suit a new use, the optics can be reconfigured rather than replaced. This flexibility is essential given the long service life of the fixtures, allowing lighting performance to adapt as operational requirements evolve over time.
Standard Aisle or High Mount
Reflectors to all arrays, no rotation, narrowing the beam angle to push light down towards the floor.
Open Area General Application
Reflectors to the centre with 5º–25º rotation to the outer bars.
Wide Angle Low Mount Height
Outer arrays rotated 25º pushes light out to the side, reducing or increasing the angle to suit requirements.
UFO High-Bay : More lights, dark areas and glare.
Power Bay: Less lights, uniform illumination across the face of the racks.
Benefits of linear arrays
PowerBay’s large linear format distributes light across the full face of the aisle, from floor to upper racking, improving visibility while typically requiring up to 30% fewer luminaires.
Uniform light across the full aisle
Conventional UFO high bays concentrate light beneath each fitting, creating high glare and pronounced dark areas between luminaires across the upper rack faces. This makes loads and racking more difficult for forklift operators to see and work around safely.
PowerBay distributes light along the aisle and across the full height of the racking, providing more uniform illumination with less glare and fewer dark areas where they matter most.
Fewer luminaires. Multiple benefits.
More effective light distribution means fewer luminaires are required. In typical high-bay applications, PowerBay can reduce luminaire quantities by up to 30%, reducing installation costs and the number of fittings and drivers to maintain over the life of the installation.

Eliminating Lost Product in High-Pressure Cold Storage
Seeka operates high-throughput packing and cold-storage facilities for export kiwifruit, avocados, and soft fruit. During peak season, produce is moved rapidly from pre-chillers into storage using forklifts in tight aisles under intense time pressure. Dropped trays don’t just damage fruit — falling produce cascades into lower stacks, causing disruption, loss, and rework.
In 2014, Seeka asked Isollux to upgrade their cool store lighting with a focus on reducing stacking related losses. We specified Light Bay as a one-for-one replacement to minimise cost, and utilised the variable optics to orientate the outer LED arrays toward the rack faces from a central mounting position.
The Result:
With a wide light distribution and fixtures oriented away from forklift drivers’ direct line of sight, illumination levels were lifted to the top of the racks, significantly improving uniformity and light penetration deep into the stacks. Increased background illumination and optimised aiming eliminated glare and retinal flare improving safety and enhancing visibility of the rack face, resulting in a 95% reduction in dropped trays compared with the previous year.
Talk to our team to learn how Isollux can help resolve lighting-related safety and productivity issues in your cold store or ware house operations.
Eliminating Dangerous Glare
Standard UFO high bays concentrate light into a small source, increasing glare. Isollux high bays distribute light across a larger surface to reduce hotspots and improve visual comfort and safety.
Proven Operational Benefits
In high-throughput cold-storage operations, improved visibility delivered by Isollux high-bay lighting has resulted in fewer dropped trays, reduced forklift impacts with lighting, and improved operational flow.
