Selecting the Right Bulb

When you’re on the hunt for the perfect bulb to bring natural sunlight vibes into your space, focusing on two key aspects will guide your decision: brightness levels tailored to your room’s surface area, and the comfort of flicker-free, glare-free lighting.

Assessing Brightness Levels and Surface Area

The right brightness level of a bulb is measured in lumens, and finding the ideal one depends on the surface area of your room. A larger room demands a bulb with high lumens to adequately simulate sunlight. For small to medium rooms, a bulb emitting around 800 lumens provides a satisfactory daylight feel similar to what’s described for full spectrum light bulbs.

  • Smaller Rooms (< 50 sq ft): 450-800 lumens
  • Medium Rooms (50-100 sq ft): 800-1,600 lumens
