Buying Guide
Key considerations when choosing small bathroom bulbs:
- Fixture size and base compatibility: Measure the socket (E26, E12, G9, etc.) and the bulb diameter to ensure a proper fit in tight spaces.
- Color temperature: For bathrooms, 2700K–5000K covers warm to daylight tones. Choose 2700K for a cozy look around mirrors; 5000K for makeup tasks or high-contrast visibility.
- Brightness and CRI: Look for higher lumens for vanity areas and CRI 80+ for accurate color rendition, which helps in grooming and makeup.
- Energy efficiency and lifecycle: LED bulbs save energy and reduce frequency of replacements, especially in hard-to-reach fixtures.
- Dimmability: If fixtures include dimmers, ensure bulbs are dimmable and compatible with the dimmer type to avoid flicker or buzzing.
- Glass and safety: Frosted or clear bulbs affect glare. Frosted options can reduce harsh reflections in bathrooms with shiny surfaces.
