What mounting options are available for this LED floodlight?
The floodlight can be mounted using either a slipfitter or trunnion mount, allowing for flexible installation based on the site’s needs and orientation. Ensure the mounting hardware is compatible with your installation location.
What are typical IESNA-style footcandle targets for applications with this floodlight?
Footcandle targets depend on fixture layout, mounting height, and spacing. Typical maintained illuminance values for outdoor or commercial spaces include:
- Parking lots: 5–20 fc average
- Perimeter or drive lanes: 5–15 fc average
- Pedestrian walkways: 10–20 fc average
- Accent or site feature lighting: 20–40 fc average
How is LPD (Lighting Power Density) calculated for this floodlight?
LPD is calculated by dividing the total wattage by the area (W/ft²). For this fixture:
- Connected load per fixture: 100W or 140W depending on selection
- Installed LPD = (Quantity × Wattage) ÷ Area (ft²)
What control features are supported by the 0–10V dimming option?
The 0–10V dimming feature allows the fixture to adjust light output based on occupancy sensors, time schedules, or centralized control systems. This feature helps optimize energy consumption by reducing output when the area is unoccupied.
What CCT and CRI are available and suitable for outdoor use?
This fixture offers selectable color temperatures (CCT) of 3000K, 4000K, and 5000K, with a CRI of 80+. 3000K provides a warm, balanced light ideal for general outdoor lighting, while 5000K offers higher contrast and clarity for security or detailed outdoor spaces.
What are the environmental and weather ratings for this floodlight?
The floodlight is rated IP65 for dust and water resistance and is wet-location listed, ensuring its durability in challenging outdoor environments such as parking lots, walkways, and outdoor security areas.
What certifications are included with this fixture?
This LED floodlight is UL Listed, FCC Compliant, and DLC Premium Listed, which is essential for rebate programs in certain areas. Always check for rebate eligibility based on DLC listing and local requirements.
What are the dimensions, finish options, and warranty details?
The fixture comes in a choice of Bronze or White finish with dimensions of 12.05" W × 6.72" D × 16.85" H. It includes a 5-year warranty, and the rated life is 50,000 hours for long-term performance.
What is the minimum operating temperature and how is the fixture suitable for extreme conditions?
The fixture is designed to operate in temperatures as low as -40°F, making it suitable for a wide range of climates, including cold weather environments often encountered in outdoor lighting applications.
