To begin, it is essential to consider any specific lighting needs in the room. For example, if there is a mantlepiece or a painting that you wish to highlight, wall wash lights can be used to create a dramatic effect. Additionally, rooms with wet areas such as showers or steam rooms may require specialized trims that are suitable for these conditions.

To create an effective lighting layout for your 12×12 room, start by measuring the dimensions of the space. Use grid paper or a similar tool to create a scaled drawing of the room. Take into consideration any shelves, workspaces, counters, or other areas that may require task-oriented lighting. This will help you visualize the placement of the can lights and ensure that they are evenly distributed throughout the room.

A general rule for spacing the lights is to divide the height of the ceiling by two. This will provide a rough estimate of how far apart the lights should be placed. However, for areas that require task-oriented lighting, such as kitchens and bathrooms, careful consideration of where the lights are aimed is necessary. This will help create efficient lighting without overloading the room or causing excessive shadows.

## Task-Oriented Lighting Considerations For Kitchens And Bathrooms

When it comes to task-oriented areas like kitchens and bathrooms, proper lighting is essential. In these spaces, it is important to consider where the can lights are aimed to ensure optimal illumination for specific tasks such as food preparation or grooming.

In kitchens, it is recommended to place the can lights above workspaces, countertops, and other areas where task lighting is required. This will help create a well-lit environment that facilitates cooking and meal preparation. Additionally, it is important to consider the color temperature of the bulbs used in these areas. Cooler color temperatures, such as daylight or cool white, are typically preferred as they mimic natural daylight and provide better visibility.

Likewise, in bathrooms, the placement of can lights should be carefully considered to ensure proper lighting for grooming activities. Aim the lights towards the vanity mirror to minimize shadows on the face and provide even illumination for tasks such as shaving or applying makeup. Adding additional ceiling lights or sconces near the shower area can also help create a well-lit space.

• Place can lights above workspaces, countertops, and other areas where task lighting is required
• Consider using cooler color temperatures for better visibility
• Aim the lights towards the vanity mirror in bathrooms to minimize shadows on the face
• Add additional ceiling lights or sconces near the shower area for a well-lit space.
