80W T5 High Output fluorescent tube with a G5 bi-pin base, producing approximately 6,150 lumens of neutral 4000K Cool White (840) illumination. The Philips MASTER TL5 HO 80W/840 combines a slim 16mm profile with powerful linear light output, making it ideal for commercial, industrial, retail, warehouse, workshop, and other compatible high-output T5 lighting installations.
What it is
The Philips MASTER TL5 HO 80W G5 840 Fluorescent Lamp is a slim High Output (HO) linear fluorescent tube designed for professional applications requiring substantial light output from a compact T5 lamp.
Its T5 construction measures approximately 16mm in diameter, with a G5 bi-pin base at each end for installation into compatible T5 lamp holders. The 80W version has a nominal tube length of approximately 1449mm, making it a long-format high-output lamp for larger commercial and industrial luminaires.
The 840 colour designation indicates a 4000K Cool White colour temperature with colour rendering in the CRI 80+ range. This provides a clean, neutral-white appearance suited to workplaces, retail areas, workshops and other environments where good visibility and practical general illumination are important.
As an 80W T5 HO lamp, it is designed to produce substantially greater light output than lower-wattage High Efficiency T5 lamps of similar dimensions. It requires compatible 80W T5 HO electronic control gear (ECG) and must not be connected directly to the 220–240V mains supply.

Safety Compliance
- Use only with compatible 80W T5 HO electronic control gear
- Do not connect directly to the 220–240V mains supply
- Confirm 80W rating, G5 base and physical tube length before replacement
- Do not substitute a lower-wattage T5 lamp simply because its physical dimensions appear similar
- 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 recycled through an appropriate lamp recycling facility
- Not interchangeable with T8 G13 fluorescent tubes
- Suitable for compatible 80W T5 HO G5 fluorescent luminaires
- Confirm 80W wattage, G5 base, tube length and ballast compatibility before installation
