The 8.5W LED ES GLS Bulb is a premier lighting solution designed to bring modern clarity and exceptional energy efficiency to your home or office. Engineered as a direct, high-output replacement for traditional 60W incandescent lamps, this bulb provides a crisp 806-lumen output while consuming significantly less power. Its classic "General Lighting Service" (GLS) shape ensures it fits perfectly into existing Large Edison Screw (E27) fixtures, making it an effortless upgrade for those seeking professional-grade illumination without the high utility costs.

This versatile bulb features a 4000K cool white color temperature, which is ideal for environments that require high visibility and a neutral, invigorating atmosphere.
