Assessing suitable household lighting primarily involves three aspects:

Color Temperature Color temperature refers to the color of light, indicating its visual warmth or coolness. For instance, 3000K closely resembles natural light:

• Warm Light: Suitable for relaxing and cozy environments like bedrooms.

• Cool Light: Ideal for study and work areas such as offices.

TIPS: Recommended color temperatures for different areas:

• Bedroom: 2700-3000K

• Living Room, Dining Room: 2900-4100K

• Kitchen: 2700-4100K

• Bathroom: 3000-6000K

Color Rendering Index (CRI) This index measures the quality of light sources:

• LED: 70-90Ra

• Energy-saving bulbs: 80-90Ra

• Daylight/Incandescent bulbs: 100Ra

• Recommended CRI for dining rooms, bedrooms: ≥80Ra

• Recommended CRI for work areas: ≥90Ra

Generally, household lighting aims for a CRI of 80-90Ra.

Types of Light Fixtures Each type of light fixture serves different purposes:

Ceiling Lamps

• Single-head ceiling lamps: Suitable for bedrooms, dining rooms.

• Multi-head ceiling lamps: Used in living rooms, can also be suitable for bedrooms.
