Living Room

Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Timeless returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
