RAB CR8/E 8 in Round Commercial Downlight — 17/25/31W / Selectable CCT / 120-277V / Integrated Emergency Battery / White

The RAB CR8/E is an 8 in round commercial recessed downlight in white finish with an integrated quick-connect emergency battery, delivering up to 3,500 lumens at 31W with a wide 85° beam angle and 90 CRI. The CR8/E features field-selectable wattage (17/25/31W) and CCT (2700K–5000K) via integrated dipswitches, with universal 120-277V input and dual dimming compatibility (0-10V and TRIAC/ELV). The built-in battery backup provides 90 minutes of emergency operation with no separate bulk battery required — ideal for commercial spaces requiring code-compliant emergency lighting.

Smart & Control Features

The CR8/E dims to 10% on compatible 0-10V and TRIAC/ELV dimming systems. Wattage and CCT are both field-adjustable via integrated dipswitches — select from 17W, 25W, or 31W and from 2700K, 3000K, 3500K, 4000K, or 5000K (default 2700K) at installation. In emergency mode, the fixture operates automatically at a set output level for 90 minutes; the battery recharges fully within 24 hours.

Construction & Design

The CR8/E features a spun aluminum enclosure that maximizes passive cooling, with a spun aluminum smooth splay reflector in white finish and a polycarbonate light diffuser for even, smooth general illumination. Stainless steel spring action clips allow for quick, tool-free installation into ceiling openings from 1/2 in to 2 in thick. Weight: 3.0 lbs (includes integrated battery).

Light Output & Performance

With efficacy up to 113 lm/W (31W), a 90 CRI, R9 > 50, and a wide 85° beam angle, the CR8/E delivers broad, high-quality commercial illumination for large spaces. Color temperature is warranted to shift no more than 200K over five years (<4-step MacAdam Ellipse binning). Rated lifespan: 50,000 hours L70 per IES LM-70.

Electrical & Installation

Operates on 120-277V with a Constant Current, Class A driver integrated on top of the fixture. Connects to junction box (not included) via MC Whip cable. Dimmable to 10% via 0-10V or TRIAC/ELV systems. Spring action clips support ceiling thicknesses from 1/2 in to 2 in. Suitable for remodel direct mount or retrofit into existing commercial downlight housings. IC rated for direct contact with air-permeable insulation; airtight certified (ASTM E283). Operating temperature: -4°F to 104°F.
