HALCO 89173 CSDL-8-LS-CS-BT-DDV

Halco 89173 CSDL-8-LS-CS-BT-DDV — 8" Commercial Slim Downlight, Baffle Trim, 18W Lumen & CCT Selectable, 120-277V Dual Dimming

The Halco Commercial Slim Downlight 89173 (CSDL-8-LS-CS-BT-DDV) is an 8-inch canless LED recessed downlight from Halco Lighting Technologies, featuring field-selectable lumen output (1100/1230/1500 lm) and five selectable color temperatures (2700K–5000K). The edge-lit LED engine sits behind a frosted PMMA diffuser with a white baffle trim, and the remote driver box supports both TRIAC/ELV and 0-10V dimming from a single unit. With 90+ CRI, up to 99 lm/W efficacy, 110° wide-flood beam, 50,000-hour L70 life, and ratings for wet locations, IC contact, and air-tight construction, this is the highest-output baffle-trim fixture in the family. cETLus listed, Energy Star certified, Title 24 and JA8 compliant. Not DLC qualified. Verify ceiling cutout (8-1/4"), trim style, and dimming compatibility before ordering.

Technical Specifications

Product Overview

The Halco 89173 is the largest baffle-trim fixture in the Commercial Slim Downlight family, offering an 8-inch aperture with an 18W LED engine that delivers the highest lumen output in the baffle series. The canless form factor uses spring retention clips for housing-free installation with a remote driver box connected by a plenum-rated cord. The larger diameter makes this the appropriate choice for spaces demanding substantial ambient light from individual downlight points.

Field-selectable DIP switches provide five CCT options (2700K, 3000K, 3500K, 4000K, 5000K) and three lumen output levels (1100, 1230, or 1500 lumens at 2700K). At maximum output, delivered lumens range from 1598 lm at 2700K to 1721 lm at 4000K, with efficacy peaking at 99 lm/W. The edge-lit design with frosted PMMA diffuser produces a smooth 110° wide-flood beam. TM-30 metrics (Rf 92, Rg 100) and 90+ CRI confirm strong color quality across all settings.

The dual-dimming driver supports TRIAC/ELV and 0-10V from one unit. As with all fixtures in this family, TRIAC/ELV dimming is limited to 120V input while 0-10V operates across 120-277V — a critical distinction for 277V commercial installations. This fixture is Energy Star certified with Title 24 and JA8 compliance but is not DLC listed, so it should not be specified where DLC qualification is needed for utility rebates. The 8-inch aperture requires an 8-1/4" ceiling cutout; verify this dimension carefully as it may differ from common 8" recessed housing cutouts.

Compatible Applications

• Commercial office spaces — Large open offices, corridors, and lobbies with higher ceiling mounting heights.
• Hospitality — Hotel lobbies, large corridors, and ballrooms.
• Healthcare facilities — Waiting areas, large exam rooms, and corridors.
• Retail — High-ceiling retail floors and showrooms.
• Residential — Large kitchens, great rooms, and open-concept living areas.
• Wet locations — Large bathrooms, covered outdoor ceilings, and soffits.
• Insulated ceilings — IC rated for direct contact with thermal insulation.

Before Ordering — Verify

• Ceiling Cutout: Confirm your ceiling cutout is exactly 8-1/4" (8.25") — this may differ from standard 8" housing cutouts.
• Trim Style: Confirm baffle trim (SKU 89173) is correct — the smooth trim version is SKU 89170.
• DLC Status: This fixture is not DLC qualified — do not specify where DLC listing is required for rebate eligibility.
• Dimming Method: TRIAC/ELV dimming requires 120V input; 0-10V dimming supports 120-277V. Verify your dimmer type and line voltage.
• Ceiling Cavity Depth: Confirm sufficient depth to accommodate the remote driver box.
• New Construction: Rough-in pans (SKU 89129 for adjustable 4/6/8") are sold separately.
• Pack Configuration: Verify the "Pack of 6" option set selection if ordering in bulk vs. single units.

Safety and Installation Guidelines

• Disconnect power at the circuit breaker before beginning installation — do not rely on a wall switch alone.
• IC rated for direct contact with thermal insulation; air tight certified per ASTM E283-2004 to prevent airflow through the fixture.
• Wet location rated — suitable for installation in showers, covered outdoor ceilings, and soffits.
• Do not install in ambient temperatures exceeding 40°C (104°F).
• The remote driver box must remain accessible and must not be buried under insulation or concealed in a manner that prevents service access.
• Use only the provided plenum-rated quick-connect cord between the driver and light engine.
• For 0-10V dimming, ensure proper low-voltage wiring from the dimmer control to the driver's 0-10V input terminals.
• For TRIAC/ELV dimming, verify the dimmer is on the manufacturer's compatible dimmer list — tested models include Lutron DVCL-153PR, CTCL-153PDH, and MACL-153MH.
• Do not modify the fixture, driver, or cord in any way — modifications will void the warranty and certifications.
• This product is mercury-free — no special hazardous waste disposal required at end of life.
