Introduction: Custom LED high bay specifications for cold storage and foundry projects become workable when the fixture schedule ties zone temperature, mounting height, control plan, and surge exposure to one configurable platform.
Freezer aisles and foundry bays look like opposite projects on paper, but the same procurement question returns: which options must be fixed before the purchase order is issued? In a cold room, the engineer manages -40°C starts, condensation during door cycles, and sealed optical assemblies. On a foundry floor, the same engineer manages 70°C ambient heat, radiant load, dust, vibration, and switching surges from large drives. A high bay chosen only by wattage and lumen output leaves those conditions unresolved. The practical answer is a configuration list: 200W or 340W, 4000K or 5000K, 110° beam spacing, 0-10V or DALI dimming, optional PIR coverage, and 10KV standard or 20KV optional surge protection.
Cold storage and foundry zones change the custom brief by changing the operating window, the failure mode, and the maintenance consequence. A freezer aisle may run at -40°C with frost, condensation during warm-up, and limited air movement around the fixture. A foundry bay may hold 70°C, with radiant heat, dust, vibration from cranes and conveyors, and electrical noise from large drives. The brief should mark those conditions zone by zone before wattage is chosen. The IRON MAN II No. HBI02 is built as a single fixture family for both environments: 120-277V input, -40°C to 70°C operating range, IP66 and IK08 protection, UL Listed, and a 5-year warranty. The configurable items are 200W or 340W, 4000K or 5000K, 110° beam, 0-10V or DALI dimming, optional PIR, and optional 20KV surge over 10KV standard. A useful brief also records mounting height, aisle width, rack face height, ambient extremes, and whether the area is washed down. In a cold room, lens access and condensation control matter because maintenance may require door time and product protection. In a foundry, dust and radiant heat change cleaning intervals and fixture placement. The same fixture family can serve both, but the option set should differ by zone. A 200W unit at 34,000 lm can fit a lower freezer aisle where spacing is tight; a 340W unit at 54,400 lm can reduce fixture count over a high foundry bay, provided thermal margin is checked. That tradeoff belongs in the brief, not in a last-minute substitution.
Power, CCT, and beam angle should be selected together because each changes the others. A higher-wattage fixture in 70°C ambient has less thermal margin than the same fixture at 25°C, while a wide beam at high mounting height can thin out illuminance unless spacing and aiming are planned with the rack layout. The custom schedule should show model, CCT, beam, mounting height, and target task or aisle illuminance for each zone.
At -40°C, cold-start behavior, material contraction, and condensation are the practical concerns. Sealed IP66 construction and a driver rated for the low end of the operating range keep the fixture stable through door cycles and defrost periods. At 70°C, thermal headroom becomes the limiting factor. The LED and driver must reject heat into air that is already hot, so a 340W fixture that runs comfortably in a 25°C warehouse needs more careful thermal design in a foundry. L70B50 50,000 hours at 25°C is a nominal rating; higher ambient temperatures will change lumen maintenance and driver life in ways that depend on the actual installation. Choose 200W, model LED-FX16HBR200 at 34,000 lm and 170 lm/W, when mounting heights are moderate, aisles are tight, or more fixtures should share the light for better vertical illuminance. Choose 340W, model LED-FX16HBR340 at 54,400 lm and 160 lm/W, when high ceilings make fixture count and maintenance access the larger cost. The tradeoff is not simply more light; more watts in a hot zone can reduce thermal margin and may call for wider spacing, better ventilation, or a lower-wattage layout with more fixtures.
4000K and 5000K are the available CCTs, and the choice should follow the task. In a foundry, 4000K gives a slightly warmer light that can reduce harsh contrast on hot metal surfaces while CRI above 80 supports reading tags, gauges, and safety markings. In cold storage, 5000K often improves contrast on white frost, pallet labels, and stainless surfaces. Neither CCT substitutes for illuminance planning. The 110° beam distributes light across the floor and lower rack faces from high ceilings, but at 10–15 m mounting heights spacing and aiming determine whether the result is uniform or patchy. A narrower beam might seem to push more light down, yet it can create hot spots under each fixture and leave aisle edges dim. A wide 110° pattern paired with the right spacing usually supports safer vertical surfaces, such as rack labels and equipment controls, without the glare that comes from concentrating output. For inspection areas, place fixtures to light the task plane rather than the floor alone; for freezer aisles, align spacing with door positions and rack faces so frost does not hide labels. The CCT and beam choice should be reviewed with the same layout drawing used for spacing.
Dimming, sensing, and surge protection are separate configuration lines. Both 0-10V and DALI dimming are supported on the IRON MAN II. 0-10V is an analog control that many facility teams already use for simple dimming and time or daylight scheduling. DALI is an open digital protocol used in industrial projects to address, group, and monitor luminaires on a control bus. DALI support and DALI certification are different scopes; the fixture is UL Listed, and DALI certification is not claimed. Cold-storage-specific and foundry-specific certifications are also not claimed; the basis for extreme-temperature use is the stated -40°C to 70°C operating range and IP66/IK08 construction. If the specification calls for DALI, confirm the control architecture, addressing plan, and gateway compatibility with the supplier before ordering. The optional PIR sensor adds motion-based control. PIRs detect changes in infrared radiation from a moving body across the sensor's detection zones, so they suit low-traffic aisles, corridors, and back-of-house foundry areas where lights would otherwise run continuously. When specifying PIR, confirm mounting height, expected coverage, and whether the sensor's field of view matches the fixture layout; in freezer rooms, plan for lens access and condensation. Surge protection is another order-time decision. The fixture ships with 10KV surge protection as standard, and a 20KV upgrade is available as an option. Industrial power systems include switching surges from large motors, compressors, cranes, and VFDs; IEEE C62.41.2 provides a framework for classifying surge environments and protection levels. For a foundry or cold storage site with heavy inductive loads or a history of driver failures after storms, mark the affected feeders for the 20KV option and keep 10KV standard on less exposed circuits. The project brief should identify which zones get 0-10V, which get DALI, which get PIR, and which get the surge upgrade. Optional features are selected at order, so a zone-by-zone matrix prevents a standard fixture from arriving where an upgraded unit was intended.
Cold storage and foundry projects can use one high bay family when the brief separates zone conditions from fixture configuration. Confirm 200W or 340W per zone, 4000K or 5000K, 110° beam spacing, 0-10V or DALI dimming, optional PIR coverage, and 10KV standard or 20KV optional surge protection. The IRON MAN II No. HBI02 covers -40°C to 70°C and 120-277V, is UL Listed, carries IP66 and IK08 protection, and provides a 5-year warranty. The result is a schedule that installation crews can follow: cold rooms may favor sealed 200W units with 5000K and PIR in low-traffic aisles, while foundry bays may favor 340W units with 4000K, wider spacing, and 20KV surge on exposed feeders. Share mounting height, zone temperatures, washdown exposure, and control plan to request a quote and confirm MOQ, price, lead time, and any project-specific documentation. The final deliverable is a configuration list per zone, not a single fixture count.
A：Cold storage projects can specify 200W or 340W power, 4000K or 5000K CCT, and the 110° beam angle to match aisle width and rack height. The 200W LED-FX16HBR200 produces 34,000 lm, and the 340W LED-FX16HBR340 produces 54,400 lm. The fixture family covers -40°C operation with IP66 and IK08 protection, 120-277V input, and 0-10V or DALI dimming. Optional PIR sensors are useful for low-traffic freezer aisles, and the 20KV surge upgrade is available on top of standard 10KV protection for sites with exposed feeders.
A：Start with the work surface and mounting height. 4000K gives slightly warmer light and less harsh contrast on hot metal, while 5000K gives a crisper look for inspection areas. CRI above 80 supports reading tags and safety markings. The 110° beam works well from high ceilings, but spacing and aiming decide whether the floor and equipment faces stay evenly lit without glare.
A：Both 0-10V and DALI dimming are supported. DALI runs as an open digital protocol for grouping and control across industrial lighting circuits, and the exact control architecture is worth checking for the project. An optional PIR sensor is available for motion-based switching in low-traffic zones. Surge protection is 10KV as standard, with a 20KV option for feeders that see heavy switching or storm exposure.
