Lighting plays a crucial role in shaping the look, feel, and functionality of any home. While it’s often overlooked in the early stages of design or renovation, proper lighting can dramatically transform a space. However, many homeowners make avoidable errors that result in dark corners, harsh glare, or an overall lack of ambience.
In this article, we’ll explore the most common lighting mistakes in home design and how you can steer clear of them to create a warm, practical, and visually appealing environment.

1. Relying on a Single Overhead Light
One of the most common lighting mistakes is using just a single ceiling light to illuminate an entire room. While an overhead fixture provides general light, it often fails to reach corners or highlight specific areas.
How to fix it:
Layer your lighting using a mix of ambient, task, and accent lighting. Floor lamps, table lamps, wall sconces, and LED strip lights can add depth and flexibility to any room.
2. Ignoring Task Lighting in Functional Areas
Functional zones like kitchens, bathrooms, and home offices need focused lighting to support daily tasks. Relying on ambient lighting alone can cause shadows and eye strain.
How to fix it:
Install under-cabinet lights in the kitchen, mirror lighting in bathrooms, and desk lamps in workspaces to ensure proper visibility and efficiency.
3. Using the Wrong Colour Temperature
Choosing bulbs with the wrong colour temperature is another frequent lighting error. A cool white bulb in a cosy bedroom, for example, can make the room feel cold and uninviting.
How to fix it:
Understand the difference between warm white (2700K–3000K) for relaxing spaces, and cool white (4000K–5000K) for functional areas like bathrooms and kitchens. Choose lighting that matches the room’s purpose.
4. Poor Lighting Control
Not being able to adjust light levels depending on the time of day or activity is a common mistake. Bright lighting at all times can feel harsh, while dim lighting may not be practical.
How to fix it:
Add dimmer switches where possible, or consider smart lighting systems that let you control brightness and colour via an app or voice command.
5. Neglecting Natural Light
Blocking out natural light with heavy curtains or poor furniture layout can make your home overly reliant on artificial lighting.
How to fix it:
Maximise natural light by keeping windows clear, using sheer curtains, and placing mirrors strategically to reflect daylight. This not only saves energy but also boosts your mood and wellbeing.
6. Wrong Size or Placement of Fixtures
Oversized chandeliers in small rooms or poorly placed wall lights can throw off the balance of a space and make it feel awkward.
How to fix it:
Measure your space before selecting fixtures, and consider proportions carefully. Place lights at eye level where appropriate, and use multiple smaller fixtures rather than one large one for more even coverage.

7. Skipping Accent Lighting
Accent lighting is often overlooked, yet it plays an essential role in adding character and highlighting architectural features, artwork, or décor.
How to fix it:
Incorporate spotlights, wall washers, or LED strips to highlight design elements. This brings dimension and personality to your interior.
