Know before you buy
The 2200K option provides a very warm, amber glow similar to candlelight, which is ideal for creating a cozy, intimate atmosphere. The 2700K option offers a slightly cooler, more neutral 'warm white' light that is better suited for functional tasks or spaces where you want a brighter, more energizing feel.
The Kilter S14d bulb is designed with signature Tala dimming technology, making it compatible with most leading-edge and trailing-edge dimmers. However, for the smoothest performance without flickering, we recommend using a high-quality LED-compatible dimmer.
The soft-frosted finish is designed to diffuse the light, reducing glare and creating a softer, more even glow. While it slightly softens the output compared to a clear bulb, it maintains a consistent 375-lumen brightness while eliminating harsh hotspots.
No, this bulb is rated for indoor use only. While it features an IP54 ingress protection rating, it is not designed to withstand direct exposure to the elements in outdoor environments.
A CRI of 95 means this bulb renders colors much more accurately than standard LEDs. It ensures that wood tones, fabrics, and paint colors in your room look vibrant and true to life, rather than washed out or distorted.
Yes, the tubular shape is specifically engineered to minimize shadowed endpoints, which is a common issue with traditional bulbs. This ensures a more uniform spread of light along the length of the bulb, making it perfect for sconces or exposed fixtures.
