STILNOVO DIPHY 8172/9090 (54 cm) — Designer LED Pendant with an “Invisible” Diffuser Effect
Stilnovo Diphy 54 cm is a premium Italian LED pendant lamp designed by Mirco Crosatto. Its form recalls a single delicate petal or leaf suspended in mid-air. The most distinctive feature is its visual effect: when the fixture is off, the transparent diffuser is almost imperceptible; when switched on, the lamp becomes an elegant luminous composition with excellent visual comfort. It is an outstanding choice above a dining table, over a kitchen island, for the living room, and for hotel and office interiors.
OptiLight — What Creates the “Almost Invisible” Fixture Effect
In the Diphy collection, the key element is a transparent PMMA diffuser. Its surface features microscopic structures that capture light from the central LED module and guide it along the edges and gentle curves of the shade. As a result:
- when switched off, the lamp maintains an exceptionally light, unobtrusive presence in the space,
- when switched on, you get an even, soft glow rather than a harsh “hot spot,”
- the light remains comfortable in areas where people spend long periods (dining rooms, living rooms, reception areas, meeting rooms).
Versions — Choose Control and Color Temperature
1) Control / Dimming
- 8172 — phase-cut (leading/trailing-edge dimming): designed for classic wall dimmers. In practice, compatibility is crucial—use LED-rated dimmers to reduce the risk of flicker and a limited dimming range.
- 9090 — DALI-Push: intended for smart installations and professional projects. Ideal when you need lighting scenes, consistent control across a facility (offices, hotels, premium apartments), or integration with building automation.
2) Light Color (2700K vs 3000K)
- 2700K: the most atmospheric warm white; ideal for relaxation zones, living rooms, and restaurants.
- 3000K: a more versatile warm white; well suited to dining areas, kitchens, and multifunctional spaces.
In practice, 2700K versions are often also marked with an “M” in the code (e.g., 8172M / 9090M)

Mini-FAQ
Does the Diphy lamp cause glare?
By design, it should not. The diffuser guides and spreads the light so the emission remains soft and comfortable, without a harsh “hot spot.”
Which should I choose: phase-cut or DALI-Push?
Phase-cut is the simplest option for standard residential installations. Choose DALI-Push if you plan on automation, lighting scenes, or a commercial/premium project.
2700K or 3000K — which is better for a dining room?
For dining rooms and kitchens, 3000K is most commonly selected as the more versatile option. 2700K is better if the priority is atmosphere and a warmer, more intimate light.
