Where is an IP20 linear strip fixture typically specified?
This fixture is commonly specified for dry, interior commercial spaces such as warehouses, back-of-house retail, distribution aisles, maintenance rooms, and general industrial circulation areas where a sealed vapor tight housing is not required.
How do the selectable wattage settings change layout and inventory planning?
Selectable wattage lets one fixture cover multiple lumen targets without changing the housing. For contractors, that can reduce SKU count on a project and allow field tuning after install if the initial foot-candle readings come in high or low.
What light output range does the 50W/60W/70W configuration provide?
The lumen packages span 6,500 lumens at 50W, 7,800 lumens at 60W, and 9,100 lumens at 70W. Use the IES file to confirm delivered illuminance based on mounting height, spacing, and surface reflectances.
What is the luminous efficacy at each wattage setting?
At 50W and 6,500 lumens, efficacy is 130 lm/W. At 60W and 7,800 lumens, efficacy is also 130 lm/W. At 70W and 9,100 lumens, efficacy remains 130 lm/W, which helps keep performance consistent when field-adjusting output.
How does a 120° beam angle behave in open warehouse ceilings?
A 120° distribution supports broad coverage and overlap between fixtures, which helps maintain uniformity across aisles and open work areas. Spacing-to-mounting-height ratios should be verified with photometrics for the target work plane.
What does a polycarbonate frosted lens do for visual comfort and glare control?
A frosted polycarbonate lens diffuses the LED source to reduce high-angle brightness and soften the appearance of the emitter when viewed from normal walking angles. In utility spaces, it also provides a durable lens option where incidental contact can occur.
How is 0–10V dimming typically used with linear strip fixtures?
0–10V dimming is commonly paired with occupancy sensors in intermittently used areas and with scheduling for after-hours setback. It also supports commissioning trim so installed light levels match the lighting schedule and reduce unnecessary wattage on the circuit.
What does “color selectable” mean for a project spec?
Color selectable means the fixture can be set to 3500K, 4000K, or 5000K in the field. This supports standardizing a luminaire family across different zones while still matching color temperature requirements by space type.
When is 3500K selected versus 4000K or 5000K?
3500K is commonly selected for retail back rooms and mixed-use spaces where a warmer neutral appearance is preferred. 4000K is frequently used for general warehouse and support areas. 5000K is specified where higher contrast supports inspection tasks, label visibility, and camera monitoring consistency.
What does “damp location” cover for this fixture class?
Damp location rating supports installation in areas subject to humidity and non-corrosive condensation, such as covered entry corridors or utility rooms. If the space is exposed to direct water spray or washdown, a wet-location rated sealed fixture is typically specified instead.
How does DLC Premium listing affect project documentation and rebates?
DLC Premium listing is commonly used to support utility rebate applications and to provide third-party verification of luminaire performance. Rebate eligibility depends on local utility rules, so confirm program requirements for paperwork and installation details.
What does ETL listing indicate for safety compliance?
ETL listing indicates the fixture has been evaluated to applicable safety standards for North American installations. For submittals, include the listing details along with voltage range, control method, and environmental rating.
How does the -4°F minimum operating temperature impact cold-weather installations?
-4°F supports operation in unconditioned spaces in cold climates and in facilities where the interior can drop near freezing during off-hours. For colder environments such as freezers, select products with lower minimum ambient ratings.
How should 100,000-hour rated life and a 10-year limited warranty be handled in maintenance planning?
Document the selected wattage and CCT setting by zone so replacements match the original commissioning. For long-cycle projects, keep the submittal package, fixture schedule, and purchase records organized, since warranty claims typically require proof of purchase and basic installation details.
