How to Choose the Right Light Bulb (2026 Guide)

TL;DR – Quick Answers

• Lumens = Brightness. Ignore wattage equivalents.
• 2700K for cozy living spaces, 5000K for task areas.
• Choose CRI 90+ for natural color and visual comfort.

Step 1: Lumens – The Most Important Number

Lumens measure brightness. The higher the lumens, the brighter the bulb.

For most American homes, a standard 800–900 lumen bulb replaces a traditional 60W incandescent.

Step 2: Kelvin (CCT) – Warm or Cool?

For cozy spaces, browse our Warm White Lighting Collection.

For ultra-warm ambiance, see our Amber Light (2000K) Collection.

For task and workspace brightness, explore Daylight 5000K Bulbs.

Step 3: Choose the Right Shape

The bulb shape affects both aesthetics and compatibility.

Step 4: CRI – Why It Matters

CRI (Color Rendering Index) measures how naturally colors appear under light.

For best results in living spaces, choose bulbs with CRI 90+.
