Bright Ideas Gone Wrong: Lighting Mistakes To Avoid When Renovating

March 27, 2026

Lighting is an essential element to consider when renovating. It is key to conjuring up the right atmosphere and for improving the functionality of rooms. There are a few classic blunders that people make when installing new lighting. Here are a few of the common mistakes that you should aim to avoid: 

The right lighting does not just illuminate a space—it defines how it feels.

Mistake #1) Only installing one big light

One overhead light is rarely enough to sufficiently illuminate a room. This is particularly the case when planning a kitchen remodel – a single bulb typically is not enough to brighten up all the recesses and corners of this room. Think about areas where additional task lighting is necessary such as countertops, desks and reading areas. Adding lighting around mirrors is also recommended for clearly seeing one’s reflection, while strategically placed uplights can add atmosphere. 

Mistake #2) Hanging pendant lights too high/low

The height at which you hang pendant lights is important to consider. Hang these lights too low in walkways and people will bump their head on them. Hang them too high, and it reduces their eye-catching suspended look. When placing pendant lights over dining tables or kitchen islands, aim to hang the light 30 to 36 inches above – this illuminates the surface without obstructed people’s eyelines. 

Mistake #3) Getting the color temperature wrong

Lighting can vary in color temperature from a warmer yellow light to a cooler blue light. Many people overlook color temperature and use the wrong toned bulbs in the wrong areas. While it is personal preference as to which lighting you prefer, most people find warmer lighting more relaxing and better for areas where you want to create comfort (like bedrooms and living rooms), while cooler lighting is more functional and better for areas of productivity (like kitchens and workshops). 

Mistake #4) Wiring in new lights incorrectly

Poorly installed lights may not only encounter faults, but could be a safety hazard. In most cases, you should avoid installing new lights yourself if you do not have electrical training. It is much safer to hire an electrician to make sure each light is properly installed so that you do not accidentally start a fire.

Mistake #5) Not using waterproof bathroom lights

Installing lighting in the bathroom? Make sure to consider the IP rating (the level of water protection) of the lights you install. Forgetting about this could lead to fires or electric shocks. IP44 is the minimum standards recommended in bathrooms, while wet areas like showers need lighting with an IP65 rating at least. 

Mistake #6) Ignoring natural light

Artificial lights are not the only way to illuminate a home. Improving natural light within your home could help to improve your mood and general health – we need sunlight exposure during the day to stimulate production of vitamin D. When planning to completely remodel rooms, consider whether you can install skylights or add glass doors to let in more light. When it comes to windowless internal rooms, you may be able to knock down internal walls or add windows above internal doors to help sunlight access these inner spaces.
