Holophane Wall Light — prismatic glass refraction, rotary socket switch, four premium finishes
Holophane is a specific type of prismatic glass engineered to refract and redistribute light in controlled, textured patterns — it is not simply frosted or ribbed glass. The prismatic surface breaks the light into soft, layered pools that play across surrounding walls and ceilings, creating an atmospheric effect that plain glass shades cannot replicate. This makes the fitting as much a decorative object as a light source. The rotary switch is integrated directly into the E27 socket — you turn the knob near the bulb fitting to switch the light on and off independently of your wall switch, which is useful for bedside or reading use. The E27 socket accepts bulbs up to 40 W maximum — do not exceed this rating. For the best visual effect with the prismatic glass, a warm filament LED at 2700 K is strongly recommended — the prismatic refraction is most visible and attractive with a point-source bulb rather than a diffuse LED. The bulb is not included. The vertically adjustable arm allows you to tilt the shade to direct the light and refraction pattern. This is a hardwired fitting — installation by a qualified electrician is recommended.
The four finish options suit different interior palettes: Brushed Steel is the most neutral and works across the widest range of interiors; Matte Black is the boldest and suits industrial and contemporary spaces; Brushed Brass adds warmth and suits heritage, mid-century, and eclectic interiors; Polished Steel is the most reflective and suits contemporary and minimalist spaces where a high-shine metallic accent is wanted. All four share the same Holophane prismatic glass shade. Mount this light in a hallway, beside a bed, in a living room, or in a study where the prismatic light effect can be appreciated on surrounding walls.

Common questions
What is Holophane glass and how does it differ from regular glass?
+
Holophane is a specific type of prismatic glass engineered to refract and redistribute light in controlled, textured patterns. Unlike frosted glass (which simply diffuses light) or plain glass (which transmits it directly), Holophane prismatic glass breaks the light into soft, layered pools that play across surrounding walls and ceilings. The effect is most visible and attractive with a warm filament LED at 2700 K, which acts as a point light source and maximises the prismatic refraction.
Is a bulb included, and which bulb works best?
+
No — the bulb is not included. The fitting uses an E27 socket with a maximum rating of 40 W. For the best visual effect with the Holophane prismatic glass, a warm filament LED at 2700 K is strongly recommended — the prismatic refraction is most visible with a point-source bulb. A diffuse LED will reduce the prismatic effect. Do not exceed the 40 W maximum.
How does the rotary switch work?
+
The rotary switch is built into the E27 socket — turn the small knob near the bulb fitting to switch the light on and off independently of your wall switch. The wall switch must be in the “on” position for the socket switch to function. This is particularly useful for bedside or reading use where you want individual control without getting up.
Which finish should I choose?
+
Brushed Steel is the most neutral and versatile — suits the widest range of interiors. Matte Black is the boldest and suits industrial and contemporary spaces. Brushed Brass adds warmth and suits heritage, mid-century, and eclectic interiors. Polished Steel is the most reflective and suits contemporary and minimalist spaces where a high-shine metallic accent is wanted. All four share the same Holophane prismatic glass shade.
Does it need to be hardwired or does it plug in?
+
This is a hardwired wall fitting — it connects directly to your wall wiring and does not plug into a socket. Installation by a qualified electrician is recommended. All mounting hardware is included in the box.
