Replacement for Satco S8421 - 32W, Daylight, Linear T8, 2-Pin Base

This 32-watt 48-inch (4-foot) T8 linear fluorescent tube replaces the Satco S8421. The T8 profile (1-inch diameter) offers improved efficiency over older T12 tubes while fitting modern electronic ballast systems. Featuring a G13 medium bi-pin base (the standard connection for linear fluorescent tubes), it's designed for drop-in replacement in commercial, industrial, and residential fixtures.

Output of 2800 lumens provides strong, effective illumination for most commercial and residential applications. The 5000K daylight color temperature produces light that feels energizing and alert - close to natural midday sunlight. This makes it well-suited for art studios, photography, task lighting, and color-critical work environments. The 85 CRI delivers noticeably better color accuracy than standard commercial lamps - a worthwhile upgrade for retail, healthcare, and residential applications where appearance matters.
