Spec-reviewed for commercial installs

Brandon Waldrop

Lead Commercial Lighting Specialist • Spec Verification + Project Documentation

TCP’s 4ft 220W linear high bay is reviewed for high-bay uniformity (30,500 lumens with 160° distribution), site consistency (4000K or 5000K options), and industrial reliability (IP65 + 0–10V controls readiness) so warehouse rows stay evenly lit without bright lanes, mixed-tone aisles, or dimming instability.

Spec review focus:
Verified for output planning at 30,500 lumens / 220W so higher mounting heights can maintain practical task-plane illumination without dim pockets between rows; verified for wide-coverage behavior using a 160° beam and frosted lens so light spreads broadly and diffuses glare, reducing harsh hotspots and improving uniformity down aisles; verified for environment posture with an IP65 rated housing so dust and moisture exposure doesn’t compromise reliability in industrial spaces and covered exterior conditions; verified for CCT discipline with availability in 4000K or 5000K so phased installs and future replacements don’t create mixed-tone rows across the same sightline; verified for 0–10V controls readiness so dimming and zoning behave predictably without flicker, dropout, or uneven curves across fixtures; verified for service-life posture with a 50,000-hour rated life for predictable maintenance cycles; verified for 120–277V compatibility for common commercial/industrial electrical conditions.

Verified configuration:
Choose one CCT per area and document it (example: “Pick module: 4000K throughout warehouse”). If dimming is used, standardize the same driver family + dimming setpoints per zone—mixed control levels are the fastest way to create visible bright lanes.
