Common Mistakes to Avoid When Buying Lighting Online

Ever unboxed a new light fixture, only to realize it’s way too small, or gives off the wrong kind of light?

You’re not alone. Shopping for lighting online is convenient, but without the right guidance, it’s easy to click “add to cart” and end up with something that doesn’t quite work in real life. From misunderstanding size to ignoring light temperature, small missteps can lead to big regrets.

Here are the most common mistakes we see, and how to avoid them.

1. Not Checking the Fixture Dimensions Carefully

What looks perfect in a product photo may feel tiny (or massive) once it’s in your space.

• Always read the full product dimensions, not just look at the images.

• Use painter’s tape or cardboard to mock up the size on your wall or ceiling before ordering.

📏 Tip: When in doubt, measure your space, then check our sizing guides to choose confidently.

2. Ignoring Ceiling Height and Hanging Clearance

A beautiful pendant or chandelier loses its charm if it hangs too low or disappears into the ceiling.

• Standard rule: leave at least 7 feet of clearance from the floor to the bottom of the fixture in open areas
  

• Over a table or island? Hang it 30–36 inches above the surface.

🪜 Check for adjustable hanging lengths if your ceilings are high, sloped, or vaulted.

3. Mixing Incompatible Color Temperatures

One of the fastest ways to make a space feel disjointed? Mixing warm and cool bulbs.

• Use 2700K–3000K for warm, cozy light in living areas and bedrooms.

• Stick with the same temperature throughout open-concept spaces.

💡 Color consistency creates a smooth visual flow, even between different fixture styles.

4. Choosing the Wrong Fixture Type for the Space

A chandelier in a low-ceiling hallway? A flush mount over a dining table? Sometimes, function gets lost in form.

• Pendant lights are best for islands and smaller focal points.

• Chandeliers shine in dining rooms, stairwells, and entries.

• Flush or semi-flush mounts work best in smaller rooms or ceilings under 8 feet.

🧠 Think about how you use the space, not just how you want it to look.

5. Overlooking the Bulb Type or Dimming Compatibility

Many fixtures are dimmable, but only if you have the right bulbs and switch.

• Double-check what kind of bulb base the fixture uses (E12? E26?).

• Want a dimmable light? Look for “dimmable” LEDs and a compatible dimmer switch.
  

⚠️ And always confirm whether bulbs are included, some fixtures ship without them.

6. Forgetting to Match the Finish Across Fixtures

Even if your styles are slightly different, mixing too many finishes (brushed nickel, matte black, gold, chrome…) in one area can feel visually noisy.

• Choose a consistent finish family throughout connected spaces.

• Brass in the dining room? Try carrying that tone into the kitchen pendants or entryway sconce.

🎨 This one detail can make your whole home feel more polished.

7. Not Thinking About Layered Lighting

Many shoppers focus on the main ceiling fixture and stop there. But good lighting comes in layers.

• Plan for ambient (main light), task (pendants, vanities), and accent (sconces, uplights).

• Each layer plays a role, and helps your home feel cozy, functional, and visually complete.

🪞 Especially in bathrooms and kitchens, layering light avoids shadows and dark corners.

Bringing It All Together

Buying lighting online can feel like a leap of faith, but it doesn’t have to be. With a few extra steps (and a little guidance), you can avoid the most common mistakes and choose fixtures that truly suit your space and style.

When in doubt, check the measurements twice, stay consistent with finishes and temperatures, and think beyond one fixture. The more intentional your choices, the more effortless your home will feel.
