Types of Light Bulbs, Light bulb bases and Light bulb sizes
Understanding the right bulb for your fixture is essential when shopping for lighting. Light bulbs come in various types, each with distinct characteristics, base styles, and sizes that determine compatibility and performance.
Common Light Bulb Types
Incandescent bulbs produce warm, soft light and are ideal for creating ambient atmospheres. They're affordable but less energy-efficient than modern alternatives.
LED bulbs are the most energy-efficient option available today. They last significantly longer, run cooler, and come in a wide range of colour temperatures to suit any space.
Halogen bulbs offer bright, crisp light and are commonly used in task lighting and accent applications. They're more efficient than traditional incandescent bulbs.
Fluorescent bulbs provide excellent energy efficiency and are often found in commercial and kitchen settings. They're available in various colour temperatures.
Understanding Light Bulb Bases
The base of a bulb determines how it fits into your fixture. Common base types include screw bases (E26 and E27 for standard fixtures), bayonet bases (B22 and BA15), and pin bases (GU10 and G9) used in spotlights and decorative fixtures.
Light Bulb Sizes
Bulb sizes are typically measured by diameter in millimetres or eighths of an inch. Standard household bulbs are usually A19 or A21, whilst smaller decorative bulbs like candle-shaped (C7 or C35) and globe-shaped (G25 or G40) options add character to vintage and mid-century fixtures.
