Where is a 175W IP69K high bay typically specified?
This configuration is commonly specified in washdown production areas, food and beverage processing, cold storage distribution, industrial kitchens, and logistics spaces where fixtures are exposed to aggressive cleaning cycles and frequent material handling activity.
What does IP69K indicate for sanitation and washdown exposure?
IP69K indicates protection for high-pressure, high-temperature washdown. It is used where luminaires may be hit directly by close-range spray during cleaning and where sealing performance must remain stable through repeated sanitation cycles.
How does IK10 rating affect fixture selection in high-traffic facilities?
IK10 is a high impact-resistance rating that is specified where fixtures may be exposed to incidental strikes from carts, pallet movement, tools, or lift traffic. It is used to reduce lens damage risk in high-abuse areas.
What is the luminous efficacy of this 175W fixture?
The fixture produces 24,500 lumens at 175W, which calculates to 140.0 lm/W. Delivered foot-candles depend on mounting height, spacing, reflectances, and any airborne vapor that can reduce light transmission.
How does a 110° beam distribution influence layout and uniformity?
A 110° distribution provides wide coverage with more control than ultra-wide optics. It supports uniform illumination across open floor areas and aisles while limiting spill beyond the target zone. Layout should be verified using the photometric file to confirm the project’s foot-candle and uniformity requirements.
What does a polycarbonate prismatic lens do in a high-bay application?
A prismatic lens diffuses light to reduce high-angle brightness that can contribute to discomfort glare when viewed from the floor or from equipment operating at height. Polycarbonate also supports impact resistance and durability in facilities with repeated washdown and frequent handling activity.
How does CRI 83 impact task visibility compared to baseline CRI 80?
CRI 83 provides incremental improvement in color rendering over CRI 80, which can support identification of labels, safety markings, and color-coded components. For color-critical inspection processes, confirm whether higher CRI or additional color metrics are required by the site specification.
How should 4000K versus 5000K be selected for this fixture?
4000K is commonly selected for general production areas where a neutral appearance is preferred for extended shifts. 5000K is typically selected where higher contrast supports inspection tasks, wayfinding, and camera monitoring consistency.
What does 0–10V dimming enable in industrial control strategies?
0–10V dimming supports integration with occupancy sensors, scheduling systems, and centralized lighting controls. It also supports commissioning trim so light levels can be set to the operational requirement without changing fixture quantities.
What does 120–277V input range support for electrical planning?
The driver supports common commercial and industrial branch circuit voltages, including 277V lighting circuits. This helps standardize specifications across sites and reduces the need for voltage-specific variants.
What does a minimum operating temperature of -40°F indicate?
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 environments. For sites combining cold operation and washdown, confirm installation practices maintain sealing integrity and match manufacturer guidance.
How do 100,000-hour rated life and a 10-year limited warranty affect maintenance planning?
A 100,000-hour rating supports long replacement cycles in extended-hour operations. For maintenance planning, record installed locations, selected CCT, control zoning, and cleaning procedures so replacements match light appearance and electrical behavior over the service term.
What does DLC Premium listing support for project documentation?
DLC Premium listing is commonly referenced for utility rebate qualification and for documentation requiring third-party verification of performance. Confirm eligibility with the local utility program, since program requirements vary by territory.
