GE SG_B001MUTPKI_US F8T5/CW Fluorescent Tube Bulb

The GE F8T5/CW is an 8-watt straight T5 fluorescent tube rated at 4,100K and 400 lumens — a compact, low-wattage light source designed for the specific physical constraint of T5 fluorescent fixtures where larger tube formats simply don't fit. The T5 designation (5/8-inch diameter) is a physical standard, not a performance tier, and the F8 prefix confirms the 8-watt power consumption. At 4,100K, the output falls in the cool white range — clean and neutral enough for task work, but without the daylight-spectrum rendering that higher color temperature sources provide. The CRI of 60 is the most significant limitation for any application beyond basic utility illumination: colors rendered under this tube will appear noticeably muted and shifted relative to their actual appearance under a high-CRI source.

This tube serves a specific replacement market: T5 fluorescent fixtures in older commercial, industrial, or appliance lighting applications where a compatible tube is needed and the performance limitations are acceptable given the application. Under-cabinet kitchen lighting, appliance interior lighting, display case illumination in non-color-critical retail, and supplemental task zones are appropriate environments. The 5,000-hour rated lifespan and GE's production quality deliver consistent output over that period without significant lumen depreciation variance. For applications where accurate color rendering matters — photography, video, art, or retail display of color-sensitive merchandise — this tube's CRI 60 rating disqualifies it, and a high-CRI LED alternative should be specified instead.
