Understanding Vanity Light Bulbs Sizes

Vanity light bulbs sizes are typically measured in inches, with the most common sizes ranging from 3 to 6 inches in diameter. The size of the bulb directly influences the amount of light it produces and the area it covers. Larger bulbs generally provide broader and more intense light, while smaller bulbs offer focused, targeted illumination.
