28W T5 High Efficiency fluorescent tube with a G5 bi-pin base, producing approximately 2,400 lumens at 25°C of bright 6500K Daylight (865) illumination. The Osram LUMILUX T5 HE 28W/865 provides efficient, uniform linear lighting for offices, retail spaces, workshops, commercial interiors, schools, and compatible T5 fluorescent fittings.
What it is
The Osram LUMILUX T5 HE 28W G5 865 Fluorescent Lamp is a slim High Efficiency (HE) linear fluorescent tube designed for professional and commercial lighting applications where efficient, evenly distributed illumination is required.
Its T5 construction measures approximately 16mm in diameter, with a G5 bi-pin base at each end. The lamp itself is approximately 1149mm long, making it a common T5 format for offices, shops, schools, commercial buildings, and industrial lighting installations.
The 865 colour designation indicates 6500K Daylight illumination with a colour rendering index of CRI 80+. This produces a crisp, cool daylight appearance particularly suited to workspaces and environments where clear visibility is important.
As a T5 HE (High Efficiency) lamp, it is designed to maximise lighting efficiency rather than the higher lamp loading of T5 HO systems. It requires compatible electronic control gear (ECG) and must not be connected directly to the 220–240V mains supply.
