IP65 Holophane glass — all bathroom zones, outdoor-capable, double insulated
IP65 is a significantly higher protection rating than the IP44 found on most bathroom pendants — it means the fitting is fully dust-tight and protected against water jets from any direction. In practice, this means it can be installed directly above a shower or bath (zone 1), in a steam room, or in a covered outdoor area such as a porch or sheltered terrace. The Holophane glass is a prismatic design originally developed for railway and industrial use — the internal prisms refract and distribute the light more evenly than a plain glass shade, reducing glare while maintaining good light output. Choose clear Holophane for a more industrial, visible-prism look; choose opal for a softer, more diffused result. The fitting is double insulated (no earth connection required), which simplifies installation in older properties where an earth wire may not be present. Seven finishes cover a wide range of interior and exterior palettes — Natural Brass is a distinctive option not found in most other fittings in this range. Dimmable with a compatible E27 dimmer switch and dimmable bulb. Hardwired; professional installation required.
The 30cm shade suits smaller bathrooms, shower rooms, and compact outdoor areas. The 40cm is better for larger bathrooms, open-plan wet rooms, or as a statement outdoor fitting above a door or in a porch. Both sizes work well in multiples.

Common questions
Can this be installed directly above a shower or bath?
+
Yes — the IP65 rating makes it suitable for all bathroom zones, including zone 1 (directly above a shower tray or bath). This is a higher rating than the IP44 required for zones 2 and 3. Always confirm zone compliance and wiring requirements with your electrician before installation.
What is Holophane glass and how does it differ from plain glass?
+
Holophane glass has internal prismatic ridges that refract and distribute light more evenly than a plain glass shade. This reduces glare and spreads the light across a wider area. It was originally developed for railway and industrial use where reliable, glare-free light distribution was essential. The prismatic pattern is also visually distinctive — it catches the light and creates a subtle texture on the shade surface.
Should I choose clear or opal Holophane glass?
+
Clear Holophane shows the prismatic pattern more visibly and gives a slightly more industrial, vintage look — the bulb is partially visible through the glass. Opal Holophane diffuses the light more completely for a softer, more even glow. Choose clear for a more characterful, industrial aesthetic; choose opal if you prefer a cleaner, more diffused result.
What does double insulated mean for installation?
+
Double insulated means the fitting does not require an earth (ground) wire connection — it has two layers of insulation instead. This simplifies installation in older properties where an earth wire may not be present in the ceiling rose. Your electrician will confirm the wiring requirements for your specific installation.
Does this need a qualified electrician to install?
+
Yes. This is a hardwired ceiling fitting — it connects directly to your ceiling wiring with no plug. A qualified electrician is required for safe installation, particularly in bathroom and outdoor locations where moisture protection and zone compliance must be verified.
