TCP’s 4ft ultra-output linear high bay is reviewed for high-ceiling uniformity (60,000 lumens with wide 160° distribution), controls-ready 0–10V performance, and mechanical durability for industrial layouts so large spaces avoid bright lanes, shadow pockets, and commissioning problems that show up after occupancy.

Spec review focus:
Verified for output planning at 60,000 lumens / 440W so high-mount applications can achieve task-plane targets without excessive fixture counts or dim gaps between rows; verified for wide-coverage behavior using a 160° beam and frosted lens so the source is diffused and spread broadly to reduce harsh hotspots and improve uniformity across aisles and open floor areas; verified for linear layout intent in a 4ft form factor so fixtures can be aligned in rows to match industrial grid logic and reduce scalloping between mounting points; verified for 0–10V controls readiness so dimming and zoning behave predictably without flicker, dropout, or uneven response across fixtures in the same zone; verified for housing durability posture using steel/aluminum construction for long-duty-cycle environments where vibration and handling are common; verified for 120–277V compatibility for standard commercial/industrial electrical conditions.

Verified configuration:
At this output level, uniformity depends on discipline: standardize mounting height, spacing, and dimming setpoints across the zone, and document the as-built control levels. One fixture left at a different dim level will create a visible “bright lane” immediately.
