Philips LED bulbs are extremely durable and consume significantly less energy than conventional light sources. Color temperature: Light can have different color temperatures, which are measured in Kelvin (K). Bulbs with a low Kelvin value produce a warm, calming light, while bulbs with a higher Kelvin value produce a cool, invigorating light. CRI: The Color Rendering Index (CRI) describes the effect of a light source on color output. Natural sunlight has a CRI of 100. The CRI of Philips LED bulbs is always above 80, ensuring natural color representation. LED technology saves up to 90% energy compared to a traditional incandescent bulb. It pays for itself quickly and saves you real money year after year. Additionally, it contributes to environmental protection. With its attractive design and familiar shape, this energy-saving LED bulb is the perfect sustainable replacement for traditional incandescent bulbs.
