49W T5 High Output fluorescent tube with a G5 bi-pin base, producing approximately 4,300 lumens of neutral 4000K Cool White (840) illumination. The Osram LUMILUX T5 HO 49W/840 combines a slim 16mm profile with powerful linear light output, making it ideal for offices, retail spaces, workshops, commercial interiors, industrial areas, and compatible T5 HO fluorescent fittings.
What it is
The T5 HO 49W G5 840 Fluorescent Lamp is a slim High Output (HO) linear fluorescent tube designed for professional and commercial lighting applications where strong, uniform illumination is required.
Its T5 construction measures approximately 16mm in diameter, while the G5 bi-pin base provides connection to compatible T5 lamp holders. The 49W HO format has a nominal tube length of approximately 1449mm, providing substantial linear illumination while retaining the narrow profile characteristic of T5 technology.
The 840 colour designation indicates a 4000K Cool White colour temperature with a colour rendering index in the 80+ range. This produces a clean, neutral white light well suited to workplaces, shops, offices, workshops, and other professional environments.
As part of Osram’s T5 HO (High Output) family, the 49W lamp is designed to produce greater light output than the similarly sized T5 HE lamp. It requires compatible 49W T5 HO electronic control gear and must not be connected directly to the 220–240V mains supply.

Key Benefits
- 49W T5 High Output (HO) fluorescent technology
- Approximately 4,300 lumens
- 4000K Cool White illumination
- 840 colour designation
- Good CRI 80+ colour rendering
- Slim T5 / approximately 16mm diameter construction
- G5 bi-pin base
- Approximately 1449mm nominal tube length
- Strong light output from a slim linear lamp
- Uniform light distribution
- Suitable for commercial and industrial environments
- Excellent lumen output for professional lighting applications
- Established Osram LUMILUX fluorescent technology
The High Output (HO) T5 platform is designed for applications where greater illumination is required from a slim fluorescent tube. This makes the 49W version particularly useful in larger commercial and industrial installations where both compact luminaire dimensions and strong light output are important.
Safety Compliance
- Use only with compatible 49W T5 HO electronic control gear
- Do not connect directly to the 220–240V mains supply
- Confirm 49W rating, G5 base and tube length before replacement
- Do not substitute a 35W T5 HE simply because it is approximately the same physical length
- T5 HE and T5 HO lamps have different electrical operating characteristics
- Isolate the electrical supply before installation or replacement
- Handle the glass tube carefully
- Avoid excessive pressure on the G5 pins
- Fluorescent lamps contain a small amount of mercury and should be disposed of through an appropriate recycling facility
- Not interchangeable with T8 G13 fluorescent tubes
