RAB HA4 4 in Round LED Downlight Module — 12W / 950–1,060 lm / Selectable CCT / 120V

The RAB HA4 is a 4 in round LED downlight module for the HALED modular recessed lighting system. Delivering 950–1,060 lm at 12W (79–88 lm/W), with field-selectable CCT from 2700K to 5000K, IC rating, airtight construction, TRIAC and 0-10V dimming, and California Title 24 JA8 compliance. Anti-UV metal construction rated for wet locations. Must be paired with a compatible 4 in HALED trim (sold separately) to complete the fixture. For 120-277V applications, order the HAD4/D10 driver separately.

Light Output & Performance

The HA4 delivers 950–1,060 lm at 12W, with efficacy ranging from 79–88 lm/W across the five CCT settings. The 45° optical lens provides uniform light distribution. With a CRI of 90, colors render accurately across all CCT selections. Color temperature is warranted to shift no more than 200K over 5 years per ANSI C78.377-2017.

Electrical & Installation

The HA4 operates at 120V / 60 Hz / 0.11A with a constant current driver. TRIAC and 0-10V dimmable — see the RAB Dimmer Compatibility List for compatible dimmers. PF: 0.9, THD ≤20%. For 120-277V applications, order the HAD4/D10 driver (sold separately). IC rated for direct contact with air-permeable insulation; airtight per ASTM-E283-04. Rated for operation from -4°F to 104°F. Recessed ceiling mount. Requires a compatible 4 in HALED trim to complete the fixture.
