POWERBAY | CMR
PowerBay CMR is a surface-mount LED high bay for cold stores and blast freezers.
Built for food-grade applications, PowerBay CMR offers a remote-mount driver for easy long-term maintenance and a choice of optics for installation at heights of up to 16 m.
Easy Installation in Blast Freezers
CMR mounts flush to PIR-insulated panels.
Slotted end plates ensure precise alignment, while insulated bolts prevent thermal transfer and seal the penetration to protect the vapour seal.
The CMR’s remote driver sits above the ceiling, removing unnecessary thermal load on HVAC, simplifying installation and providing easy access for long-term maintenance.

Built for Harsh Conditions
Engineered for harsh industrial environments, PowerBay CMR combines IP66 ingress protection with IK10 impact resistance and food-grade polycarbonate lenses.
Broad Range of Ambient Temperatures
Designed for continuous operation in extreme cold environments down to −25°C as standard, with short-duration exposure at higher ambient temperatures to support maintenance.
Class Leading 10 Year Warranty
PowerBay CMZ is built for endurance, delivering steady lux output with minimal lumen depreciation and backed by a comprehensive 10-year warranty.
Adaptive Optics
PowerBay CMR’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
Driver replacement at 100,000 hours extends service life to match the LED’s maximum lifetime, with spare parts available for repairs if accidental damage occurs.

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.
Built in Driver Protection:
All our drivers feature multiple layers of protection with auto-restart. So you can be sure your investment is protected. Standard features include:
- Under Voltage Protection [UVP]
- Over Voltage Protection [OVP]
- Short Circuit Protection with auto recovery [SCP]
- Over Temperature Protection [OTP]
- Surge Protection [DM 6kV, CM 10kV]
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.
