What facility types specify a 240W IP69K high bay with IK10 impact protection?
This configuration is commonly specified in washdown production areas, food and beverage processing, cold storage distribution, industrial kitchens, and high-abuse logistics zones where fixtures can be exposed to aggressive cleaning and mechanical impact from carts, lift traffic, or material handling.
What does IP69K indicate in terms of washdown exposure?
IP69K indicates protection for high-pressure, high-temperature washdown. It is specified where luminaires may be hit directly by close-range spray during sanitation cycles and where sealing performance must hold up to repeated cleaning.
How does IK10 impact rating apply to a high-bay luminaire?
IK10 is a high impact-resistance rating used where fixtures may be struck by equipment, tools, or incidental contact in industrial environments. In high-bay applications, it is often specified to reduce lens damage risk in areas with frequent material handling.
What does 33,600 lumens at 240W translate to in efficacy?
The fixture produces 33,600 lumens at 240W, which calculates to 140.0 lm/W. Maintained workplane results depend on mounting height, spacing, reflectances, and any airborne vapor or particulate that can reduce delivered light.
How does a 110° beam distribution affect spacing and uniformity at typical high-bay mounting heights?
A 110° distribution provides wide coverage with more control than ultra-wide optics. It supports uniform illumination across open work areas and aisles while limiting excessive spill beyond the target zone. Final spacing should be validated using the project photometric layout to meet foot-candle and uniformity requirements.
What does a polycarbonate prismatic lens do compared to a clear optic?
A prismatic lens uses controlled diffusion to spread light and reduce high-angle brightness that can cause discomfort glare in open-floor areas. Polycarbonate also supports impact resistance and durability in spaces where cleaning cycles and incidental contact are common.
How does CRI 83 differ from standard CRI 80 in industrial task environments?
CRI 83 provides incremental improvement in color rendering over CRI 80, which can help with label identification, color-coded wiring recognition, and visual differentiation of materials in production areas. For color-critical inspection, confirm whether higher CRI or additional color metrics are required by the process specification.
How should 4000K versus 5000K be selected for this high-output high bay?
4000K is commonly selected for general production areas where a neutral appearance is preferred for extended shifts. 5000K is often selected where higher contrast supports inspection tasks, wayfinding, and camera monitoring consistency.
What does 0–10V dimming support in large facilities with varying occupancy?
0–10V dimming supports integration with occupancy sensors, scheduling, and centralized lighting control systems. It also supports commissioning trim so installed light levels can be set to the operational requirement without changing fixture quantities.
What does 120–277V input range support for electrical standardization?
The 120–277V driver supports common commercial and industrial branch circuit voltages, including 277V lighting circuits. This can reduce voltage-specific variants across facilities and simplify procurement.
What does a minimum operating temperature of -40°F indicate for cold storage deployment?
A -40°F minimum operating temperature indicates the LED system and driver are rated for cold starts and continuous operation in freezer and cold storage environments. For facilities combining cold operation and washdown, confirm installation details maintain sealing integrity and match manufacturer guidance.
What does DLC Premium listing support for rebates and documentation?
DLC Premium listing is commonly referenced for utility rebate qualification and for documentation requiring third-party performance verification. Confirm eligibility with the local utility program, since program rules vary by territory.
How should 100,000-hour rated life and a 10-year limited warranty be used for maintenance planning?
A 100,000-hour rating supports long replacement cycles in facilities that operate extended hours. For planning, document installed locations, control zoning, and the selected CCT so any future replacements match light appearance and control behavior. Retain submittals and photometric files to keep layout performance consistent over the service life.
