LEDVANCE T5 Circular Fluorescent Lamp 22W GZ10q Base (Sold as 12)

OSRAM T5 Circular 22W/865 GZ10q Fluorescent Tube Replacement (Sold as 12)

The OSRAM/LEDVANCE T5 Circular 22W lamp is a specific GZ10q 4-pin fluorescent tube designed for use in specialized ceiling or decorative fixtures that require an internal ballast. It delivers powerful, consistent, and shadow-free illumination across a 360-degree spread.

Critical Replacement Information:

• Like-for-Like Replacement: Fluorescent tubes must be replaced with the same wattage (22W) and base type (GZ10q) to ensure compatibility with the existing control gear/ballast.

• Light Quality: The 865 color code (6500K Cool Daylight) provides a very bright, white light, ideal for workspaces, garages, and commercial areas requiring high visual clarity.

• Dimensions: Features a slim T5 (16mm) tube diameter and approximately 185mm overall diameter.

• Warning: This product contains mercury and must be disposed of safely and responsibly.
