Color Temperature Information

Color temperature refers to the visible color of a white light source, or how the actual light appears to your eye. It is measured on the Kelvin (K) scale, numbered from 1,000 - 10,000. • Warm light is understood to be up to 3000K (ranges from yellow to reddish) • Cool light is typically 3500K – 5000K and will have hues from blue to white.

Lumens

Lumens measure the amount of light produced by a bulb. Put simply, the more lumens a light bulb has, the brighter the light. For lights that are further from the area they are lighting (such as downlights in a 12- foot ceiling) – you will want a higher lumen output to ensure functional illumination. For task applications, higher lumen output is also desired to provide bright, direct light over work areas.

Equivalent Light Output

Pay careful attention to the bulb manufacturer’s caution statements regarding use in enclosed fixtures or dimmer compatibility.
