Overview

The Ushio BC8832 CF9SE/841 is a 9-watt compact fluorescent lamp designed for use in fixtures with a 2G7 4-pin base. Producing 600 lumens of 4100K cool white light, it delivers a clean, neutral tone that works well in office environments, commercial spaces, and task lighting applications. The 82 CRI rating ensures acceptable color rendering for everyday use, and the 10,000-hour average rated life means fewer replacements and lower maintenance costs over time.

Operating at just 60 volts, this single-ended compact fluorescent is an energy-efficient option for recessed downlights, desk lamps, and other fixtures designed around the 2G7 pin configuration. As a direct replacement bulb, its primary value lies in matching the specific base type and output characteristics that many existing commercial and residential fixtures require. For facilities still operating CFL-based lighting systems, the Ushio BC8832 provides a dependable, brand-name option that keeps fixtures running without the need for costly fixture upgrades.
