LA Lighting WSE251 Sensor Controlled LED Wraparound — 4000 lm Nominal — 4000K or 5000K — White

The LA Lighting WSE251-4-4L-MSPCSD(LW)-DRDM-UNV-1/840 and WSE251-4-4L-MSPCSD(LW)-DRDM-UNV-1/850 sensor controlled LED wraparounds offer a 4,000 lm nominal package in separate fixed 4000K and 5000K versions. Both use 120–277V input, a 0–10V dimming driver, and an integrated PIR motion sensor with photocell. UL listed for the USA and Canada and suitable for damp locations, these white fixtures hold the light off when sufficient ambient light is present and increase or decrease illumination in response to motion when ambient light is low.

Performance & Light Output

At 4000K, the standard-efficacy 4,000 lm nominal, 4-foot system-data entry lists 26.7W, 3,631 lm, and 136.0 lm/W. Its fluorescent equivalents are 1-F54T5HO or 2-F32T8. These delivered-output and power figures apply to the 4000K configuration.

Both offered color packages provide 80+ CRI. Service life is greater than 50,000 hours at L70. System data is based on 120V input; actual performance may differ with the installation environment and application.

Smart & Control Features

Both offered SKUs include the MSPCSD(LW) PIR motion sensor with photocell and wide sensor lens.

• Ambient-Light Response: Holds the luminaire off when sufficient ambient light is present, regardless of motion.
• Motion Response: When ambient light levels are low, increases or decreases illumination in response to motion.
• Wide Coverage: Cone-shaped LW sensor lens supports 8–10 ft mounting heights with coverage specified as 6× mounting height.

The integrated sensor is part of these two configured fixtures, rather than a separately ordered sensor accessory.

Electrical

The DRDM driver operates on 120–277V input and provides 0–10V dimming. High-efficiency drivers are coupled with long-life LEDs.

Construction

Housing: Aluminum housing with riveted end plates and side knockouts for 1/2-inch conduit.

Lens & Optics: Snap-on frosted acrylic radial lens.

Finish: Pre-painted baked white polyester finish with a minimum reflectance of 86%.

Environmental Sealing: Neoprene gasketing on the end caps; suitable for damp locations. The standard-efficacy 4000K system-data entry lists an ambient range of −4°F (−20°C) to 95°F (35°C).

Dimensions: The 4-foot model measures 52 × 6 × 4⅝ inches (length × width × height).

Installation & Mounting

Mounting Layout: The 4-foot backplate drawing shows 48-inch on-center mounting dimensions. This is a fixture mounting dimension, not spacing between luminaires.

Conduit Access: Side knockouts accommodate 1/2-inch conduit.

Sensor Mounting Height: The included LW sensor lens is specified for 8–10 ft mounting heights, with coverage specified as 6× mounting height.

Certifications & Rebates

• UL listed for the USA and Canada; suitable for damp locations.
• Made in the USA.
• BAA compliant.

Typical Applications

• Stairwells: Integrated PIR sensing increases or decreases illumination in response to motion when ambient light is low.
• Parking Structures: Suitable for damp locations, matching this manufacturer-listed application.
• Passageways: The LW sensor lens supports 8–10 ft mounting heights with wide sensor coverage.
• Workrooms: Fixed 4000K or 5000K options provide 80+ CRI.
• Restrooms: The integrated photocell holds the luminaire off when sufficient ambient light is present, regardless of motion.
