35W T5 High Efficiency fluorescent tube with a G5 bi-pin base, producing approximately 3,300 lumens of neutral 4000K Cool White (840) illumination. The Philips MASTER TL5 HE 35W/840 combines a slim 16mm profile with efficient linear light output, making it ideal for offices, retail spaces, schools, workshops, commercial interiors, and compatible T5 fluorescent fittings.
What it is
The Philips MASTER TL5 HE 35W G5 840 Fluorescent Lamp is a slim High Efficiency (HE) linear fluorescent tube designed for professional lighting applications where efficient, uniform illumination and long operating life are required.
Its T5 construction measures approximately 16mm in diameter, while the G5 bi-pin base provides connection to compatible T5 lamp holders. The 35W HE format has a nominal lamp length of approximately 1449mm, making it a common long-format T5 lamp for offices, retail environments, schools, commercial buildings, and other professional installations.
The lamp produces approximately 3,300 lumens with a 4000K Cool White colour temperature. Its 840 colour designation indicates a colour rendering index in the 80+ range, providing a clean, neutral white appearance with good colour rendering for everyday commercial and professional environments.
As part of the Philips MASTER TL5 HE range, this lamp is designed primarily around high luminous efficiency. It requires compatible electronic control gear (ECG) and is not intended for direct connection to the 220–240V mains supply.
