## Long description

Osram Dulux S/E 7 W is a compact fluorescent linear bulb with a T12 tube profile and a 2G7 four-pin base. The lamp provides approximately 400 lumens of warm white light (around 3000 K) with a Color Rendering Index (CRI) of 80 and an estimated lifetime of 20,000 hours. Designed for applications that require low power consumption and a linear CFL format, this bulb fits fixtures and luminaires prepared for 2G7 compact fluorescent tubes.
Advantages
The bulb combines low energy use at 7 W with a stable warm-white output suitable for general interior lighting. With a CRI of 80 it renders colours naturally for most everyday tasks. The 2G7 base provides secure mechanical and electrical connection in compatible fixtures, while the T12 form factor allows use where a linear compact fluorescent tube is required. The long rated life reduces replacement frequency compared with standard incandescent lamps.
Suitable for
 Task lighting in offices and workstations
 Retail display cases and shelving illumination
 Corridors, stairwells and communal interior areas
 General-purpose fixtures that accept 2G7 T12 compact fluorescent lamps
