Both versions share the same ∅ 12 cm wall footprint and projection — only height differs:

Compact (H 40 cm): powder rooms, hallways, narrow walls, accent placements where you want the Art Deco silhouette without it dominating.
Tall (H 60 cm): bathroom vanities, formal entries, staircase walls, larger spaces where the verticality reads as a statement.

Wall sconces typically center at ~165 cm / 65″ from the floor, but vanity placement is often closer to ~152 cm / 60″ — measure to your eye level for the best result.

Yes — the Pillar is rated for indoor wet-area bathroom installation. That said, install it outside the immediate splash zone (not directly above the shower head, not where it can be sprayed by the showerhead or tub faucet). Best placement is flanking a vanity mirror, on a hallway leading into the bathroom, or above a vanity counter where it stays dry. Confirm exact local code requirements with a licensed electrician.

One E14 small Edison screw bulb (LED recommended; not included) sits behind the reeded glass column. For the most striking Art Deco look, choose a candle-tip ("torpedo") bulb in warm color temperature (2700K-3000K) — the slim shape complements the vertical reeded refraction.

Dimmable when paired with a dimmable E14 LED bulb and an LED-rated wall dimmer.

Hardwired wall mount — connects to a standard wall junction box behind the brass rectangular backplate. Requires an external wall light switch for on/off control (not included). Professional electrician recommended, especially for bathroom installations where local wet-zone codes apply.
