54W T5 High Output fluorescent tube with a G5 bi-pin base, producing up to approximately 4,750 lumens of bright 6500K Daylight (865) illumination. The Osram LUMILUX T5 HO 54W/865 combines a slim 16mm profile with powerful linear light output, making it ideal for offices, workshops, industrial facilities, commercial interiors, car parks, and compatible T5 HO fluorescent fittings.
What it is
The Osram LUMILUX T5 HO 54W G5 865 Fluorescent Lamp is a slim High Output (HO) linear fluorescent tube designed for professional, commercial, and industrial lighting applications requiring strong, evenly distributed illumination.
Its T5 construction measures 16mm in diameter, while the G5 bi-pin base provides connection to compatible T5 lamp holders. The lamp body is approximately 1149mm long, with an overall length of approximately 1163mm depending on the measurement reference.
The 865 colour designation indicates a 6500K Cool Daylight colour temperature with a colour rendering index of CRI ≥80. This creates a crisp daylight appearance particularly suited to workspaces, industrial environments, workshops, and other areas where clear visibility is important.
As part of the T5 HO (High Output) family, the 54W lamp is designed to produce substantial light output from a relatively compact tube. Osram/LEDVANCE specifies optimum luminous performance at an internal luminaire temperature of approximately 35°C. The lamp requires compatible electronic control gear (ECG) and is not designed for direct mains connection.
