## Long description

Synergy21 S21-LED-BS00072 is a T8 LED bulb that delivers 3,400 lumens from 20 W of input power. The lamp produces cool white light at a correlated colour temperature of 6100 K with a Colour Rendering Index (CRI) of 80, a beam angle up to 140° and an estimated lifetime of 35,000 hours. It is designed for use in tubular T8 fittings and operates from a wide mains range of 100–240 V at 50–60 Hz, providing high-brightness, energy-efficient illumination for commercial and industrial environments.
Advantages
The Synergy21 T8 LED bulb offers high luminous efficacy by converting 20 W of input power into a strong 3,400 lm output, reducing energy consumption compared with traditional fluorescent T8 tubes. With a 6100 K cool white output and CRI 80, the lamp maintains acceptable colour reproduction for tasks requiring clear, bright light. A long rated lifetime of 35,000 hours and a wide beam angle (up to 140°) deliver long service intervals and broad area coverage, while compatibility with standard tubular T8 fittings simplifies installation and replacement.
Suitable for
 Commercial premises such as retail spaces and offices requiring bright cool white lighting
 Industrial environments and workshops where high lumen output and durability are needed
 Storage areas, corridors and utility rooms where wide beam distribution is beneficial
