The largest bulb in the range, Sphere IV is an impressive technical and aesthetic achievement. The deliberately oversized form and perfectly spherical shape make it a design feature to be celebrated, while representing the impressive engineering feat involved in its creation. Characterised by its Dim to Warm and flicker free behaviour, it offers warm and ambient light when dimmed down from 100-0%. The dimensions are Ø 15 x H 19 cm. This bulb is equipped with Dim to Warm technology, allowing for a smooth transition between 2000-2800K, while maintaining excellent colour rendition. It offers high-quality comfort, allowing for both functional lighting for working and a very warm amber atmosphere in the evening. The white sphere shape is ideal for modernising your lighting fixtures.
