GE F4T5/WW/CB 4W Warm White Fluorescent Light Bulb

The GE F4T5/WW/CB is a 4-watt T5 fluorescent replacement lamp designed for compact fixtures that require a miniature bi-pin G5 base. Operating at a warm white color temperature of 3,000K, it produces 140 lumens of soft, comfortable light that works well in under-cabinet installations, small desk lamps, and accent lighting applications where a gentle glow is preferred over high-output illumination.

With a rated life of 5,000 hours—roughly two years under normal use—this bulb offers dependable performance without frequent replacements. The 4-watt draw makes it extremely energy-efficient, though the trade-off is its limited brightness and a CRI of just 52, which means it won't render colors with the accuracy needed for tasks like artwork or detailed color-critical work. For its intended purpose as a compact, low-power fluorescent replacement, it delivers consistent, warm light at a minimal operating cost.
