Alabaster lighting has moved from a niche specification choice to one of the most sought-after design decisions in luxury residential and hospitality interiors. Its appeal is straightforward: no other material transforms artificial light the way alabaster does. The stone absorbs, diffuses and re-emits light with a warmth and softness that reads as almost natural — neither harsh nor flat, but genuinely luminous.
But alabaster lighting covers a wide spectrum of products, quality levels and price points. This guide explains what to look for, what to avoid and how to make the right choice for your project.
What Is Alabaster?
Alabaster is a fine-grained natural stone — a form of gypsum — prized since antiquity for its translucency and warmth. When carved thin and backlit, it allows light to pass through while diffusing it completely, eliminating any visible hotspot or harsh point of light. The result is a glow that feels organic rather than artificial.
Because alabaster is a natural material, every piece is unique. The natural veining, colour variation and translucency differ from piece to piece — which is part of its appeal and also something to factor into your specification.
Alabaster vs synthetic alternatives
Some lower-price lighting uses resin or polymer materials described as "alabaster effect" or "stone effect". These are fundamentally different products. Resin diffusers are consistent and predictable but lack the natural variation and warmth of genuine stone. At Araco Interiors, our alabaster lighting — including the full CTO Lighting range and Araco Lumière collection — uses genuine honed alabaster throughout.
Types of Alabaster Lighting
Alabaster pendant lights
The most popular alabaster lighting format. A pendant uses the stone as its primary diffuser — either a solid carved dome, a disc, a cylinder or an irregular organic form — hung from a cable or rod. The stone filters the light source entirely, creating an even, warm glow. Our alabaster pendant collection includes designs from Araco Lumière (Kairo, Vale, Novar, Aven, Sora, Tovi) and CTO Lighting (Lucid, Hepworth pendants, Avalon).
Alabaster wall lights
Wall lights use alabaster as either the primary diffuser or a secondary decorative element mounted on a metal bracket. The stone creates a pool of warm light against the wall surface, functioning simultaneously as a decorative object and a light source. Our alabaster wall light collection includes Araco Lumière designs (Halo, Flux, Beam, Glow, Oryn, Vela, Rune) and CTO Lighting's Gaia, Hepworth wall light and Lucid wall designs.
Alabaster ceiling lights
Close-to-ceiling designs using alabaster as a flush or semi-flush diffuser. Ideal for rooms where a pendant would feel intrusive — lower ceilings, hallways, bathrooms — they provide the warmth of alabaster without the drop. Our Araco Lumière Juno and Loren ceiling lights are available across multiple wattages (12W to 72W) for different room sizes.
Alabaster chandeliers
CTO Lighting's Avalon chandelier is the definitive expression of alabaster in a chandelier format — a ring of honed alabaster, hand-finished in antique bronze or satin brass, that creates cascading warmth in generous spaces. Available in Medium, Large, X-Large and Halo configurations.
How to Specify Alabaster Lighting: 6 Key Questions
1. What size do I need?
For pendant lights, a general rule: the diameter of the alabaster piece should relate to the scale of the space around it. A single pendant above a dining table should be approximately one-third to one-half the width of the table. In a living room, a pendant of 30–45cm diameter suits standard ceiling heights; larger pieces suit double-height or generous spaces.
2. What wattage do I need?
Alabaster diffuses and reduces the effective output of a light source — by approximately 30–40% compared to an open fitting. This means you need a higher lumen output than you might expect. For a dining room pendant, aim for 800–1200 lumens from the fitting. Our Araco Lumière ceiling lights range from 12W (suitable for a small bedroom or bathroom) to 72W (suitable for a generously proportioned open-plan room).
3. Should it be dimmable?
Yes — without exception. Alabaster lighting at full brightness can be very warm and intense in an intimate space. Being able to reduce it to 20–30% in the evenings is what makes it atmospheric rather than overpowering. Many CTO Lighting pieces are available in DALI-A or DALI-B variants for integration with smart dimming systems. Standard LED-compatible trailing-edge dimmers work well with most of our other alabaster pieces.
4. What colour temperature?
Alabaster already produces a warm, amber-toned diffusion regardless of the bulb used. Combining this with a warm white bulb (2700K) creates an exceptionally warm, intimate atmosphere. For most residential settings, 2700K–3000K is correct. For spaces that need more functional light (a studio, a kitchen), 3000K provides warmth without sacrificing colour accuracy.
5. Can I use it in a bathroom?
Many of our CTO Lighting alabaster wall lights — including Hepworth and Gaia variants — are available in IP44-rated versions, suitable for use in bathroom Zone 2. Always confirm the IP rating on the product page or with our team before specifying for a wet room or bathroom zone. Alabaster should not come into direct contact with water.
6. What is the lead time?
Araco Lumière pieces ship from stock in most cases, typically within 5–10 working days. CTO Lighting pieces are made to order with typical lead times of 8–12 weeks. For project planning, confirm lead times with our team before committing to a programme. Our trade team can advise on staggered delivery scheduling for phased projects.
Care and Maintenance
Alabaster is a natural stone and requires appropriate care to maintain its appearance.
- Dusting: Wipe with a soft, dry microfibre cloth. Do not use abrasive cloths or scourers on the stone surface.
- Marks: For light marks on the stone surface, a very slightly damp cloth can be used carefully. Do not use cleaning chemicals, solvents or acidic products on alabaster — they will damage the stone permanently.
- Grease: Avoid touching the alabaster surface with bare hands where possible — skin oils can transfer to the stone over time. Most designers specify a cleaning cloth in the installation room.
- Light source replacement: Follow the manufacturer's guidelines for the specific fitting. Most of our alabaster pieces use integrated LED modules that do not require lamp replacement for the lifetime of the fitting.

Frequently Asked Questions
Is alabaster lighting expensive?
Genuine alabaster lighting represents a significant investment compared to synthetic alternatives — reflecting the cost of natural stone, skilled craftsmanship and precision engineering. Expect to pay £300–£800 for quality Araco Lumière alabaster pieces, and £800–£5,000+ for CTO Lighting designs depending on the collection and complexity. The investment is justified by longevity, uniqueness and the unmatched quality of light the material produces.
Will my alabaster lighting look exactly like the product image?
Because alabaster is a natural stone, each piece will have slightly different veining, colouration and translucency to others from the same collection. This natural variation is part of what makes each light unique. We are happy to share specific images of the available stone upon request for our CTO Lighting pieces.
Can alabaster lighting be used outside?
No — alabaster is not suitable for exterior use. It is a porous stone that will be damaged by moisture, temperature variation and direct exposure to the elements. All our alabaster lighting is specified for interior use only.
What is DALI dimming on CTO Lighting pieces?
DALI (Digital Addressable Lighting Interface) is a professional dimming protocol used in smart lighting systems. DALI-A means the dimming module is concealed within the ceiling cavity (no visible aesthetic change to the fitting). DALI-B means the fitting has a deeper ceiling rose to accommodate the module. Our trade team can advise on the right specification for your lighting control system.
