Calcedonia Alabaster Tube Wall Sconce
Calcedonia Alabaster Tube Wall Sconce
The Calcedonia is an alabaster tube wall sconce — two slim natural-stone tubes set above and below a round backplate, offset for a quiet, architectural rhythm. The translucent alabaster glows warm from a built-in LED, showing the natural veining in the stone. With a copper-tone metal frame, it suits a bathroom, a hallway, a bedside wall, or either side of a mirror. Available in three heights.
Offset stone tubes
Two slim alabaster tubes sit above and below the backplate, offset for a calm, architectural look.
Natural alabaster glow
Translucent stone glows warm from within and shows natural veining; each tube varies.
Built-in warm LED
An integrated warm-white LED lights both tubes — no bulbs to buy or fit.
Three heights
15.7″, 19.7″, or 23.6″ tall, each Ø2.4″ — pick the scale that fits your wall or mirror.
Copper-tone frame
A copper-tone metal backplate and collars warm the natural stone and read soft against the glow.
Default configuration
Two offset alabaster tubes on a round copper-tone metal backplate, lit by a built-in warm-white LED. Hardwired, AC 110–240V. Choose 15.7″, 19.7″, or 23.6″ tall.
Light source — integrated LED
The tubes are lit by a built-in warm-white LED, so there are no separate bulbs to buy or fit. The warm light brings out the natural veining in the alabaster. If a module ever needs service, we'll help — just email us.

- Hardwired wall sconce — we recommend a licensed electrician; shut off power at the breaker before wiring.
- The round backplate covers a standard wall junction box; confirm your box placement and height before install.
- The LED is built in (warm white) — there are no bulbs to install; just hardwire and mount.
- Handle the alabaster tubes by the metal collars, not the stone, and seat them gently; natural stone can chip if knocked.
- Wipe the stone and frame with a soft, dry cloth; avoid water, harsh cleaners, and abrasive pads on the natural alabaster.
- Alabaster is a natural stone, so the veining, tone, and translucency vary from piece to piece; the photograph shows a representative sample.
Does the Calcedonia take bulbs, or is the LED built in?
The LED is built in — a warm-white integrated LED lights both alabaster tubes, so there are no separate bulbs to buy or fit. The warm light brings out the natural veining in the stone. If a module ever needs service, we can help with replacement parts.
What sizes does it come in?
Three heights: 15.7″, 19.7″, and 23.6″, each about 2.4″ in diameter. The shorter size suits a bedside or powder room; the taller sizes flank a mirror or fill a hallway wall. All three use the same copper-tone frame and built-in LED.
Is the stone real, and why does each one look different?
The tubes are natural alabaster, a translucent stone. Because it's natural, the veining, tone, and how the light passes through vary from piece to piece — that variation is the character, not a flaw. The photograph shows a representative sample.
Can I use it in a bathroom?
It suits a powder room or over a mirror in a dry or lightly humid spot. Keep it away from direct water and shower spray, and have a licensed electrician confirm placement meets local code for the room. Wipe the stone with a dry cloth only.
What is the warranty and support?
2-year warranty on the frame and wiring. Because the LED is built in, there are no bulbs to replace; if a lit module ever needs service, we'll help with replacement parts. Email support replies within one business day.
Sizing & questions
Every piece is made to order in our own atelier — here is what most clients ask before choosing theirs.
How do I clean the alabaster and copper frame?+
Wipe both with a soft, dry cloth. Avoid water, harsh cleaners, and abrasive pads on the natural stone. Handle tubes by the metal collars, not the stone itself.
Do I need an electrician to install this?+
Yes, we recommend a licensed electrician. Hardwired installation requires shutting off power at the breaker. The round backplate covers a standard wall junction box.
Will the alabaster veining look the same as the photo?+
Each piece of alabaster is natural stone, so veining, tone, and translucency vary. The photo shows a representative sample; your sconce will have its own unique character.

Lighting is more than just functional—it’s a defining element of your home’s design. Choosing the right size fixture ensures both visual balance and proper illumination. In this guide, we’ll show you how to determine the ideal fixture size for your space, plus expert tips for chandeliers, pendants, flush mounts, sconces, and more.
1. How to Calculate the Perfect Fixture Diameter
Selecting the correct fixture size starts with your room’s dimensions. A fixture that’s too small or too large can disrupt the balance of your space. Use this simple formula to find the right diameter:
Step 1: Measure the room’s length and width (in feet).
Step 2: Add the two numbers together.
Step 3: Convert the total from feet to inches — that’s your ideal fixture diameter.
Example:
For a 12 x 14 ft room → 12 + 14 = 26 → Ideal fixture diameter ≈ 26 inches.
2. Determining Fixture Height
Ceiling height plays an important role in choosing fixture proportions.
Formula:
Room height (in feet) × 2.5–3 = Fixture height (in inches)
Example:
For a 10 ft ceiling → 10 × 2.5–3 = 25–30 inches fixture height.
3. Ideal Hanging Heights
- Dining Table: 32–36 inches above the tabletop.
- Kitchen Island: 32–36 inches above the countertop.
- General Rooms: Keep at least 7 feet clearance from the floor to the bottom of the fixture.
For multiple pendants, each should be roughly ¼ the length of the surface below and evenly spaced.
5. Room-by-Room Tips
Living Room
Use chandeliers or pendants as statement pieces scaled to the room size. Add table or floor lamps for layered lighting and cozy ambience.
Dining Room
Choose a chandelier ½ to ⅔ the width of your table. For long tables, consider two or three smaller pendants spaced evenly.
Kitchen
Hang pendants 32–36 inches above the island for balanced task lighting. Add under-cabinet lighting to brighten work areas.
Bedroom
Use flush or semi-flush fixtures for soft ambient light. Pair with bedside lamps or sconces placed at eye level when seated.
Bathroom
Mount vanity sconces 65–70 inches from the floor, one on each side of the mirror to avoid shadows. Use flush mounts for even overhead lighting.
6. Mirror Light Size Guide (Above-Mirror Installation)
Choosing 2-Head or 3-Head Fixtures:
- Mirrors up to 50 inches wide: A 2-head fixture provides clean, balanced illumination.
- Mirrors over 50 inches wide: A 3-head fixture offers more even light distribution.
- Extra-wide mirrors: You may install two 2-head fixtures spaced evenly for better symmetry and coverage.
Installation Height:
- Mount the fixture approximately 4–6 inches above the mirror.
- Always center the fixture with the mirror for visual balance.
7. Ceiling Height Guide
- Low Ceilings (≤8 ft): Use flush or semi-flush mounts.
- Standard Ceilings (9–10 ft): Ideal for chandeliers and pendants.
- High Ceilings (10+ ft): Choose taller, statement fixtures that draw the eye upward.
Rule of Thumb: Allow 2.5–3 inches of fixture height per foot of ceiling height.
Final Thoughts
Choosing the right light fixture size means balancing scale, height, and function. By following these simple calculations and room-specific tips, you’ll ensure every space feels perfectly lit and visually balanced.
