The LEDVANCE OSRAM L 40W/865 G10Q is a single-ended round fluorescent lamp with a G10Q base. It produces extremely uniform illumination without shadows, making it well suited to general-purpose lighting in large spaces that require consistent, glare-free coverage.

The 865 designation confirms a colour rendering index group of 1B (Ra: 80–89) and a daylight colour temperature of 6500K. It is dimmable and operates across ambient temperatures from -20 to +45°C, covering refrigerated storage through to hotel lobbies, warehouses, and supermarkets.
