What types of facilities specify an NSF-rated 100W high bay?
This configuration is commonly specified in food processing and packaging areas, cold storage, breweries, dairies, commercial kitchens, and sanitation-controlled production spaces where fixtures must support hygiene protocols and frequent cleaning.
What does IP69K indicate for washdown exposure?
IP69K indicates the luminaire is protected for high-pressure, high-temperature washdown. This rating is specified where fixtures can be hit directly by aggressive cleaning spray at close range as part of routine sanitation cycles.
How does the wet-location rating relate to sanitation environments?
Wet-location rating supports installation where the fixture can be exposed to direct moisture. In washdown spaces, it is used alongside the IP rating to address both moisture exposure and sealing performance during cleaning.
What does 14,000 lumens at 100W translate to in efficacy?
The fixture produces 14,000 lumens at 100W, which calculates to 140.0 lm/W. Maintained workplane results depend on mounting height, spacing, and the reflectance characteristics of the room surfaces.
How does a 115° beam distribution affect spacing and uniformity?
A 115° distribution provides wide coverage for open production floors and aisle layouts. It supports uniform illumination across the work plane while maintaining optical control so spacing can be optimized without creating strong hot spots directly under each fixture. Layout should be confirmed using the photometric file for the project’s target foot-candles.
Why specify a polycarbonate shatterproof lens in food and washdown areas?
Polycarbonate shatterproof lenses are specified where lens breakage must be avoided over product lines and packaging stations. Polycarbonate also supports impact resistance in environments with lift traffic, frequent handling, and repeated cleaning cycles.
How should 4000K versus 5000K be selected in production and cold storage spaces?
4000K is commonly specified where a neutral appearance is preferred for extended occupancy and general production. 5000K is typically selected where higher contrast supports inspection tasks, label reading, and camera performance.
What does 0–10V dimming support in multi-shift operations?
0–10V dimming supports integration with occupancy sensors, scheduling controls, and centralized lighting control systems. It also supports commissioning trim so installed light levels can be aligned to the operational requirement without changing fixture quantity.
How does 120–277V input range affect electrical planning?
The 120–277V driver supports common commercial and industrial branch circuit voltages, including 277V lighting circuits. This can reduce voltage-specific variants across projects and simplify standardization.
What does the -40°F minimum operating temperature indicate for cold environments?
A -40°F minimum operating temperature indicates the driver and LED system are rated for cold starts and continuous operation in freezer and cold storage conditions. For facilities that combine cold operation with washdown, confirm installation practices maintain sealing integrity and match manufacturer guidance.
What does DLC Premium listing support for rebate documentation?
DLC Premium listing is commonly referenced for utility rebate qualification and for submittals that require third-party verification of performance. Confirm eligibility with the local utility program, since requirements vary by territory.
What should be recorded for service planning based on rated life and warranty?
The fixture is rated for 50,000 hours and includes a 5-year limited warranty. For service planning, document the selected CCT, dimming control zoning, and any washdown procedures so replacements match light appearance, electrical behavior, and sanitation requirements.
