Lithonia LDN Cylinder

LDN Cylinder Series

General illumination cylinders in damp and wet location surface, pendant (stem and cable), and wall mount configurations.

Key Features

• Flexible configurations — The LDN Cylinder line (e.g. 4", 6", 8" versions) supports multiple mounting options (surface-mount, pendant/stem or cable mount, wall mount), making it versatile for different spaces (open ceilings, corridors, lobbies, etc.)
• Wide lumen range & strong output — Depending on model you can get anything from modest to very high light output. For example, the “4-inch” version produces up to ~2,000 lm, while larger 8″ cylinders can deliver up to 20,000 lm — powerful enough to replace high-wattage HID fixtures.
• Good efficacy & glare control — LDN cylinders typically deliver around 75+ LPW (lumens per watt) with a 55° cutoff (reducing glare), enabling efficient, comfortable general illumination.
• Lighting quality options — Available in multiple color temperatures (CCTs, e.g. 2700 K to 5000 K) and CRI choices (e.g. CRI 80 or 90), giving flexibility for different ambient or task-lighting needs.
• Dimming & controls compatibility — Many LDN Cylinder fixtures include dimming drivers (e.g. eldoLED, 0–10 V) and can integrate with the manufacturer’s lighting control ecosystem (e.g. networked controls via nLight), useful for energy savings and smart building integration.
• Wet / damp-location rated — Many versions are rated for damp or wet locations, so they can be used in more demanding environments (garage, covered exterior, etc.) without sacrificing reliability.
• Scalable design for different ceiling heights / spaces — Because of the multiple sizes (4", 6", 8") and lumen packages, LDN Cylinders can be used in everything from office interiors to high-ceiling atria or warehouses — a flexible, scalable choice. Acu

Typical Use

• Commercial interiors (offices, corridors, lobbies): 4" or 6" cylinders give good balance of light and glare control for standard- to mid-height ceilings.
• High-ceiling spaces (retail, atria, warehouses): 8" high-output cylinder variants produce high lumen output — suitable to provide uniform general illumination where traditional HID lights were used.
• Flexible architecture/retrofits: Because of multiple mounting types and wet-location ratings, LDN Cylinders can retrofit older spaces or adapt to varied architectural needs while meeting modern lighting requirements.
• Energy-efficient / controlled lighting: Good efficacy + dimming/controls integration + LED lifespan makes them cost- and energy-efficient for long-term operation.
