Technical Specifications

Minor note: this item's spec sheet lists “Style: Traditional,” while the 2700K and 3000K siblings (S21324, S21325) list “Style: Transitional” despite being otherwise spec-identical. Likely just an inconsistency in Satco's own internal data rather than a real design difference; not reflected as a meaningful spec above.

Product Overview

The Satco S28485 is an 11.5W LED A19 bulb on a GU24 twist-lock base, with a frosted plastic lens and a high CRI of 90+ for accurate color rendering. It delivers 1,100 lumens at 4000K (Cool White) with a wide 220° beam angle for broad, even light distribution.

This lamp is dimmable on 120V circuits using phase-cut (Triac-type) dimmers, and is rated for damp locations and totally enclosed fixtures. It is cULus Listed and carries a 5-year limited warranty.

This SKU is part of Satco’s 90 CRI, CEC/Title 20-compliant A19 line, and is explicitly California Title 24 Listed — approved for sale in California energy-code-regulated projects. The GU24 base’s twist-lock design prevents standard screw-base (E26) bulbs from being installed in fixtures designed for high-efficacy-only lamps, a common requirement in California new construction and renovation.

Compatible Applications

• Indoor residential and commercial lighting — General-purpose GU24 fixtures.
• Totally enclosed fixtures — Approved for use where airflow is restricted.
• California Title 20/24-regulated projects — New construction and renovation requiring compliant, high-efficacy GU24 lamps.
• Damp locations — Covered outdoor fixtures and humid indoor spaces (not for direct wet exposure).

Before Ordering — Verify

• Base Type: This is a GU24 twist-lock base, not a standard E26 medium screw base — confirm the fixture has a GU24 socket before ordering.
• Dimmer Compatibility: Compatible with 120V phase-cut (Triac-type) dimmers only — confirm dimmer type before specifying for a dimmed application.
• Color Temperature: Confirm 4000K is correct — this 90 CRI/CEC-T20 GU24 family also includes: S21324 (2700K), S21325 (3000K), S28485 (4000K).
• CRI / Compliance Tier: This is the 90 CRI, CEC/Title 20-compliant tier. Satco also offers a lower-cost, non-T20, 80 CRI GU24 version in this same wattage class (items S29814 at 2700K and S29804 at 4000K) for projects that don't require CA compliance — confirm which tier the project needs.
• Fixture Rating: Damp location rated — not for direct wet/outdoor exposure despite being enclosed-fixture approved.
• Voltage: Confirm the application is 120V.

• Disconnect power before installing or replacing this lamp.
