Technical FAQ Deep-Dive
What are the electrical and photometric specifications for this mini LED flood light?
This Keystone Technologies knuckle-mount LED flood light is selectable between 15W, 20W, or 25W, producing 1,998–3,292 lumens. It operates on 120–277V, supports 0–10V dimming, and provides 80+ CRI. Color temperature is field-selectable.
What mounting options and controls are available?
This fixture includes a knuckle mount for adjustable aiming and a built-in photocell for dusk-to-dawn operation. Ensure the mounting surface and arm can support the weight and intended orientation.
What IESNA-style footcandle targets are typical for this light?
Illuminance depends on mounting height and spacing. Typical maintained values include:
- Walkways or small area flood: 5–15 fc average
- Accent lighting or small wall washes: 10–20 fc average
- Exterior stair or ramp zones: 5–10 fc average
Footcandle targets should always be confirmed using a photometric layout for spacing, tilt, and reflectance.
How is LPD (Lighting Power Density) calculated for this fixture?
LPD = total connected load ÷ area (W/ft²). For example:
- Connected load per fixture: 15–25W depending on selection
- Installed LPD = (Quantity × Selected Wattage) ÷ Area (ft²)
Dimming reduces energy use during low-activity periods but does not affect code-calculated LPD, which is based on connected wattage.
Which environmental ratings support outdoor use?
This fixture is IP65-rated and suitable for wet locations, withstanding wind-driven rain and splashes. Ensure seals and mounting interfaces are maintained for long-term performance.
What certifications and listings apply?
UL Listed and DLC Premium Listed, supporting eligibility for rebate programs and compliance verification on submittals.
What are the physical dimensions and finish options?
The fixture measures 6.02" W × 7.24" D × 8.17" H. Finish options include Bronze or White, allowing coordination with architectural or site conditions.
What minimum operating temperature and warranty are provided?
This flood light is rated down to -40°F and includes a 5-year warranty. Use this information to plan lifecycle energy performance, maintenance schedules, and replacement cycles.
