Lithonia Lighting STL2 Surface Volumetric LED Wraparound — 20W — 4000K — White

The Lithonia Lighting STL2 20L EZ1 LP840 surface volumetric LED wraparound delivers 2,156 lm at 20W with fixed 4000K light. This 2-foot fixture operates on 120–277V and uses an eldoLED EZ1 driver with 0–10V dimming to 1%. Damp listed and CSA certified to meet U.S. and Canadian standards, its crescent-shaped linear-faceted refractor balances illumination on vertical and horizontal work surfaces.

Performance & Light Output

At 20W, this fixed 4000K configuration delivers 2,156 lm at 107.8 lm/W. The crescent-shaped refractor obscures individual LED images and uniformly washes the fixture surface with light.

The LEDs provide 82 CRI, and the STL is rated for L90 performance at 60,000 hours. Performance values are design or typical values measured under laboratory conditions at 25°C; actual performance may vary with the application and environment.

Electrical

The eldoLED EZ1 driver operates on 120–277V input and supports 0–10V dimming to 1%. The eldoLED driver design provides flicker-free operation, low-current inrush, 89% driver efficiency, and low EMI.

Construction

Housing: Roll-formed code-gauge steel housing with decorative die-cast end caps.

Lens & Optics: Impact-modified linear-faceted refractor with light-diffusing film. An angled mounting surface and crescent-shaped refractor integrate individual LED images. The refractor attaches to the die-cast ends with a hook-and-pin design; injection-molded plastic light traps prevent light leaks between shielding and end plates and center the diffuser on the channel.

Finish: Metal parts are post-painted in white polyester powder coat for smooth, finished edges.

Environmental Listing: Damp listed.

Dimensions & Weight: 22-7/8 × 10-1/8 × 3-7/8 inches (length × width × depth); 8 lb.

Installation & Mounting

Mounting Options: Suitable for unit or row installation with surface or suspended mounting. Individual stem-mounted installations require two single-stem hangers.

Accessories Sold Separately: Suspension hardware is sold separately. For aircraft-cable suspension, one compatible suspension kit is required at each suspension point.

• Aircraft-Cable Suspension: STACG36F1 and STACG36F2, sold separately, are adjustable 36-inch aircraft-cable gripper suspension kits; STACG72F1 and STACG72F2, sold separately, provide 72-inch suspension.
• Dimming Power-Feed Suspension: STACGFD36F1 and STACGFD36F2, sold separately, provide 36-inch adjustable aircraft-cable suspension with a 120–277V power feed for 0–10V dimming; STACGFD72F1 and STACGFD72F2, sold separately, provide 72-inch suspension.

Ceiling Types: F1 kits accommodate most T-bar and screw-slot grid ceiling applications, including on-grid and off-grid installations. F2 kits accommodate recessed or surface-mounted horizontal junction-box applications.

Certifications & Rebates
