Getting the lighting right in a room can feel a little like Goldilocks: too bright in one spot, too dim in another, until you finally land on light that’s just right. Most lighting mistakes come down to a handful of repeat offenders, and each one has a straightforward fix. Here are the five we see most often, and how to correct them.
1. The Room Feels Uncomfortable
The Culprit: Missing layers of light. Too little, or even too much, of one type of lighting in a room can be uncomfortable. People are remarkably sensitive to light, and harsh or dim spaces can quietly cause discomfort or even anxiety.
The Fix: Every well-lit room draws on three types of lighting working together.
Ambient: Overall, general lighting for the room. Task: Focused lighting for a specific function, like reading or cooking. Accent: Lighting used to highlight or decorate a space.
Layer these three thoughtfully, and a room can shift from bright and functional to soft and atmospheric as needed. Always put hardwired fixtures on a dimmer for that added control. An over-the-table suspension light for ambient lighting, paired with wall sconces for accent, is a favorite designer formula for warming up a space with layers.
2. The Bathroom Is Too Dark
The Culprit: Asking the vanity light to do too much. A good task light at the vanity is essential for grooming, but relying on a single fixture to light the entire room, even a small one, tends to leave the space feeling dark and dingy.
The Fix: Bring in multiple sources of light. A few recessed lights, or a well-placed flushmount or semi-flushmount fixture, will provide the ambient light the rest of the room needs while keeping the vanity bright and functional.
3. You Can't See What You're Cooking
The Culprit: A lack of task lighting. Even well-executed ambient light can leave countertops and work surfaces in shadow, since it’s coming from above or behind you rather than exactly where you need it.
The Fix: Undercabinet lighting is a must for a well-lit kitchen. Focus task lighting on the areas where you actually work, whether that’s a simple line of puck lights or a fully integrated system with added features like outlets or Bluetooth speakers. Undercabinet lighting doubles as soft accent lighting when the kitchen isn’t in active use, a small detail with an outsized effect.
4. The Light Is the Wrong Size
The Culprit: Falling for a fixture without considering scale. An undersized light can feel like an afterthought, while an oversized one looms over the room and pulls attention from everything else.
The Fix: Choose a fixture that suits both your decor and the scale of the room it’s going into. Plenty of formulas exist to help calculate the right size, but one reliable, low-tech method is to mock up the fixture’s dimensions in cardboard first, a trick designers rely on to preview how a shape will actually sit in the room before committing.
5. It's Too Bright in Here
The Culprit: Too many recessed lights. It’s easy to get overzealous with recessed lighting, and too many can leave a living room feeling like a lobby or a hallway lit like a runway.
The Fix: Start with a lighting plan. When remodeling or building, take the time to map out the needs of the space, ideally with input from a lighting specialist who can account for square footage and the lumen output of the fixtures you’re considering. If the lights are already installed, add controls: put them on separate switches so they can be operated independently, or add a dimmer for finer control.

Common Lighting Mistakes FAQ
What is the most common lighting mistake in a home?
Relying on a single light source to do every job in a room is the most common mistake. Expert Tip: layer ambient, task, and accent lighting in every room, and add dimmers so each layer can be adjusted independently.
How many light sources should a room have?
Most rooms benefit from at least three: one ambient source for overall light, one task source for a specific function, and one accent source to add depth. Expert Tip: if a room only has overhead lighting, adding a table lamp or sconce is often the fastest upgrade.
Can a light fixture be too big for a room?
Yes. An oversized fixture can overwhelm a space and draw attention away from everything else in the room. Expert Tip: mock up a fixture’s footprint with cardboard before buying to see how the scale actually reads in the space.
Is it possible to have too much recessed lighting?
Yes, overusing recessed lighting is a common way rooms end up feeling overlit and flat. Expert Tip: build a lighting plan before installation, and put recessed fixtures on a dimmer or separate switch so they’re not your only source of light.
