HALCO 89171 CSDL-4-LS-CS-BT-DDV

Halco 89171 CSDL-4-LS-CS-BT-DDV — 4" Commercial Slim Downlight, Baffle Trim, 13W Lumen & CCT Selectable, 120-277V Dual Dimming

The Halco Commercial Slim Downlight 89171 (CSDL-4-LS-CS-BT-DDV) is a 4-inch canless LED recessed downlight from Halco Lighting Technologies, featuring field-selectable lumen output (660/820/1075 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 93 lm/W efficacy, 110° wide-flood beam, 50,000-hour L70 life, and ratings for wet locations, IC contact, and air-tight construction, this fixture delivers versatile, high-quality illumination for commercial and residential spaces. cETLus listed, Energy Star certified, Title 24 and JA8 compliant. Not DLC qualified. Verify ceiling cutout (4-5/16"), trim style, and dimming compatibility before ordering.

Technical Specifications

Product Overview

The Halco 89171 is a 4-inch commercial slim LED downlight designed for fast, housing-free installation in both new construction and retrofit applications. Its canless form factor uses spring retention clips to grip the ceiling opening directly, eliminating the need for a separate recessed housing or junction box enclosure. The LED engine and driver are housed in separate components — the light engine sits in the trim housing while the driver occupies a remote box connected by a plenum-rated quick-connect cord, allowing flexible placement within the ceiling cavity.

This fixture offers two levels of field selectability via DIP switches: a five-position CCT switch (2700K, 3000K, 3500K, 4000K, 5000K) and a three-position lumen output switch (660, 820, or 1075 lumens at 2700K). Actual lumen output at the highest setting varies by CCT, ranging from approximately 1082 lm at 2700K up to 1167 lm at 4000K per the manufacturer's photometric data. The edge-lit LED design paired with the frosted PMMA diffuser and baffle trim produces a wide-flood 110° beam with smooth, even distribution and minimal glare. The 90+ CRI and strong TM-30 fidelity scores (Rf 91, Rg 98) ensure accurate color rendering across commercial and residential environments.

The dual-dimming driver supports both TRIAC/ELV and 0-10V protocols from the same unit, which simplifies stocking and specification. However, an important caveat applies: TRIAC/ELV dimming is limited to 120V input, while 0-10V dimming operates across the full 120-277V range. Installers must verify their dimmer type and line voltage before wiring. This fixture is not DLC qualified, so it should not be specified where DLC listing is required for utility rebate eligibility. Rough-in pans for new construction are sold separately and are not included.

Compatible Applications

• Commercial office spaces — Conference rooms, open offices, corridors, and lobbies.
• Hospitality — Hotel guest rooms, lobbies, hallways, and common areas.
• Healthcare facilities — Patient rooms, hallways, exam areas, and waiting rooms.
• Retail — Display accent lighting and general ambient illumination.

• Wet locations — Bathrooms, showers, covered porches, and soffits.
• Insulated ceilings — IC rated for direct contact with thermal insulation.

Before Ordering — Verify

• Ceiling Cutout: Confirm your ceiling cutout is exactly 4-5/16" — this fixture requires a specific opening size and is not adjustable.
• Trim Style: Confirm baffle trim (SKU 89171) is correct — the smooth trim version is SKU 89168.
• 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 89104, 89129) 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.
