Commercial Downlight Round LED

The CDL houses a spun aluminum reflector finished in a shadow-free haze that distributes light evenly while minimizing visible hot spots. The aluminum housing serves double duty as a heat sink, drawing heat away from the LED engine to help maximize rated life. Trim rings are offered in black, white, haze, and rosé finishes across round open and round wall wash trim shapes, with mounting diameters scaled to each trim size for a clean, flush fit against the ceiling plane.

Installation is handled through durable spring clips that allow fast, tool-minimal flush mounting directly into an existing ceiling opening — ideal for remodel work where a new construction frame kit isn't practical. For ground-up construction, an optional new construction frame kit can be ordered separately and installed ahead of drywall, with or without an integrated junction box and whip. The fixture is damp location listed, extending its use beyond dry interior ceilings alone.

The CDL operates on field-selectable wattage output — 10/15/20W, 27/34/40W, or 40/50/60W depending on the output tier selected — at line voltages of 120–347V for the FS1, FS1C, and FS2 tiers and 120–277V for the FS3 tier, with a power factor greater than 0.9. Delivered lumens and efficacy scale with the selected wattage, ranging from roughly 800 to over 6,000 lumens at efficacies between 75 and 109 lm/W depending on output and trim configuration. Color temperature is field selectable across three settings per tier — 3000K/3500K/4000K for FS1, FS2, and FS3, or 3000K/4000K/5000K for FS1C — with a minimum CRI of 80. The fixture is 0-10V dimmable, dimming continuously down to 10% for the FS1, FS1C, and FS2 output tiers or down to 1% for the FS3 tier, with beam angles varying by trim from roughly 57° for standard round distribution up to 77° for wall wash configurations. 

Part of the Candela Lighting downlight family: The CDL Commercial Downlight Round LED shares its field-selectable output platform with the CDLSQ Commercial Downlight Square LED, giving specifiers a matched round-and-square pairing from Candela Lighting. Both fixtures use the same FS1, FS2, FS3, and FS1C output modules, so a project can mix round and square trims throughout a space while keeping light output and color temperature consistent from room to room.

Choosing an output tier: The CDL's FS1 and FS1C tiers suit lower ambient lighting needs such as guest rooms, corridors, or accent applications, while FS2 steps up to typical open-office and retail illumination levels. FS3 is the highest-output tier, sized for larger spaces or higher ceilings where greater lumen density is needed, and is available exclusively in the 6-, 8-, and 10-inch sizes. Matching the tier to the space avoids over- or under-lighting a ceiling plane and keeps energy use proportionate to the application.

Choosing a color temperature: Each output tier offers three field-selectable CCT settings, so the same fixture can be dialed toward a warmer, more residential feel or a cooler, more task-oriented feel without changing hardware. Warmer settings tend to suit hospitality and residential-adjacent spaces, while cooler settings are often preferred in retail and office environments where visual clarity is the priority.

New construction vs. remodel installation: The CDL's spring-clip mounting allows it to be installed directly into an existing ceiling opening for remodel projects, with no frame kit required. For new construction, the optional frame kit — available with or without an integrated junction box and whip — should be set ahead of drywall to establish the rough-in opening. Confirm which approach fits the project timeline before specifying accessories.

Dimming compatibility: The CDL's 0-10V driver has confirmed compatibility with a range of commercial dimming and control systems, including Leviton IP710-DL and IP710-LF, Lutron PowPak 0-10V Dimming Module and Diva-Dvtv, Hubbell NX Distributed Room Controller, Cooper Greengate Room Controller, nLight nPP16D, and WattStopper DLM. Confirm dimmer compatibility with the project's electrical contractor prior to installation, particularly when specifying the FS3 tier's 1% dimming floor.

Emergency lighting option: For applications requiring code-compliant emergency egress lighting, an external 120-277V emergency LED driver can be added, providing up to 120 minutes of illumination in the event of a power failure. Emergency drivers are ordered as separate accessories and should be specified early in the project to confirm ceiling space and wiring requirements.

Ordering logic: The CDL SKU follows the format CDL-[Size]-[Trim]-[Output], for example CDL-4-ROW-FS1 for a 4-inch round open white trim at the FS1 output tier. Frame kits and emergency drivers are ordered as separate accessory SKUs under the same CDL family prefix.
