The number of wall lights needed in a room depends on various factors, including the room size, layout, desired lighting effect, and personal preference. As a general rule of thumb:

Accent Lighting: For accent lighting or decorative purposes, one or two well-placed wall lights can add a touch of elegance and create a focal point.

Ambient Lighting: If you're using wall lights as a primary source of ambient lighting, consider spacing them evenly around the room. Two to four sconces can provide sufficient illumination, depending on the room size.

Task Lighting: In areas where specific tasks are performed, such as above a vanity or a reading nook, one or two wall lights can provide targeted lighting for those activities.

Ultimately, the ideal number of wall lights will depend on your personal preference, the functionality of the space, and the overall lighting plan for the room. It can be helpful to experiment with different configurations or seek advice from a lighting professional to determine the best placement and quantity for your specific needs.

The rules for wall lights, or sconces, can vary depending on personal preference and the specific needs of your space. Here are some general guidelines to consider:

Placement: Mount wall lights at eye level or slightly above in living rooms and hallways. In bathrooms, position them at a height that complements the vanity or mirror.

Spacing: Place sconces about 6 to 8 feet apart for even light distribution, but adjust as needed based on fixture size and desired effect.

Dimmers: Install wall lights with dimmers for brightness control and ambiance.

Style and Coordination: Choose wall lights that complement your room's design and coordinate with other fixtures.

Electrical Safety: If unsure, consult a professional electrician for proper installation and adherence to safety codes.

Remember, these are general guidelines, and it's essential to adapt them to your specific space and preferences.

In many cases, a combination of upward and downward lighting can provide a balanced and versatile lighting scheme. It allows you to have ambient lighting with upward fixtures and targeted lighting with downward fixtures. Experimenting with different lighting options and seeking professional advice can help you make an informed decision that suits your space and lighting needs.
