Fost Large Bulb PET Felt Acoustic Lamp

Introduction

Fost Large Bulb delivers acoustic performance at scale. The 118cm dome addresses noise in open-plan offices, large meeting rooms, and dining areas where standard lighting falls short. Use a single lamp above a conference table or cluster several across an open space. Fits any standard bulb, giving you flexibility in light selection. Available in 11 colours.

Size matters for acoustic control. The 118cm diameter creates enough volume to absorb meaningful sound levels in spaces where multiple conversations happen simultaneously. Position above large tables where noise concentrates, or distribute across ceiling areas that need broader acoustic treatment.

Available in 11 Colours
