Lighting a home interior for a high-end commercial can be a complex task, but with the right approach, it can be done to achieve a cinematic look. Here are some tips on how to light a home interior for a high-end commercial:

Use natural light: Natural light can be a great way to create a warm and inviting atmosphere in a home. Use large windows and sliding doors to let in as much natural light as possible.
Use soft light: Soft light is a great way to create a cinematic look in a home interior. Use softboxes, umbrellas, or diffusion material to soften the light and create a warm and inviting atmosphere.
Use practical lights: Practical lights, such as table lamps and floor lamps, can be a great way to add depth and dimension to a home interior. Use dimmable lights to control the intensity of the light and create a sense of atmosphere.
Use color gels: Color gels can be a great way to add mood and atmosphere to a home interior. Use warm colors, such as orange and yellow, to create a warm and inviting atmosphere, and cool colors, such as blue and green, to create a more dramatic and moody atmosphere.
Use backlight: Backlight can be a great way to add depth and dimension to a home interior. Use backlight to create a sense of depth and to highlight certain features of the home.
Use a light meter: A light meter can be a great way to ensure that the lighting in the home is consistent and that the exposure is correct. Use a light meter to measure the light in different areas of the home and make adjustments as needed.

It's important to keep in mind that lighting is a creative process and it's best to experiment with different lighting setups and techniques to achieve the desired look. Also, it's essential to have a good communication with the director, the DP and the gaffer to make sure you are achieving the desired look and mood that they want to convey.
