The Complete Bulb Guide: How to Choose the Right Bulb for Every Fixture

The Right Bulb Makes All the Difference

You can have the most beautiful lamp in the world, but pair it with the wrong bulb and the effect falls flat. Too bright, too cool, the wrong fitting, or the wrong shape — bulb selection is one of the most overlooked aspects of interior lighting. This guide covers everything you need to know.

Understanding Bulb Fittings

Before anything else, you need to know your fitting type:

• E27 (Edison Screw) — The most common fitting. Used in floor lamps, table lamps, and pendant lights
• E14 (Small Edison Screw) — Smaller version, used in candelabra and decorative fixtures
• GU10 — Twist-and-lock fitting, used in recessed spotlights and track lighting
• B22 (Bayonet) — Push-and-twist fitting, common in ceiling lights

Choosing the Right Bulb Shape

Bulb shape affects both the light distribution and the aesthetic of your fixture:

• A-shape (standard) — The classic bulb shape. Versatile and widely compatible
• Globe (G-shape) — Round, decorative. Beautiful in exposed fixtures and bathroom mirrors
• Candle (C-shape) — Elegant, tapered. Perfect for chandeliers and wall sconces
• Edison filament (ST64, G95) — Vintage aesthetic with visible filament. Ideal for industrial and rustic interiors
• Reflector (R-shape) — Directional light. Used in spotlights and recessed fixtures

Lumens vs Watts: Think Brightness, Not Power

With LED bulbs, watts no longer indicate brightness — lumens do. Here's a quick reference:

• 250–450 lumens — Soft accent lighting, bedside lamps
• 450–800 lumens — Standard room lighting, equivalent to a 60W incandescent
• 800–1600 lumens — Bright task lighting, kitchens, home offices
• 1600+ lumens — High-output lighting for large spaces

Smart Bulbs: Control Your Light from Anywhere

Smart bulbs connect to your home Wi-Fi and can be controlled via app, voice assistant, or automation schedules. Key benefits include:

• Adjust brightness and color temperature without a dimmer switch
• Set schedules — lights that turn on at sunset and off at bedtime automatically
• Create scenes — save your favorite lighting settings for different moods
• Compatible with Alexa, Google Home, and Apple HomeKit

Lamp Shades & Accessories: The Finishing Touch

The right lamp shade transforms a bare bulb into a design feature. Consider:

• Drum shades — Clean, modern, diffuses light evenly in all directions
• Empire shades — Classic tapered shape, directs light downward
• Coolie shades — Wide, flat profile, maximizes light spread

Shade material matters too — fabric shades create a warm, soft glow, while metal and glass shades produce a crisper, more directional light.
