Classic LED E27 Lamp. With LED lamps, you save energy and get long-lasting, high-quality light. An LED lamp can shine for up to 22 years. LEDs therefore only need to be replaced rarely. They consume up to 90% less energy than classic incandescent bulbs. Philips LED lamps are also more comfortable for the eyes, as they meet the strict EyeComfort* criteria regarding flicker, stroboscopic effects, and glare. - Energy efficiency class: E - Lamp base: E27 - Protocol: None - Smart Home: Not compatible - Color temperature Kelvin: 4000 K - Total power: 13 W Energy Efficiency Class EPREL: Products with the EU energy label are registered in the EPREL database (European Product Registry for Energy Labelling) and thus meet the legal minimum requirements of the EU Ecodesign Regulation. If energy consumption exceeds the specified reference value, the product may not be registered in EPREL or placed on the market. Products of energy efficiency class A have particularly low energy consumption compared to other devices in the same product group. This reduces the environmental impact associated with the use phase, particularly energy demand and resulting emissions. Information on measurement methods and energy consumption... Filament Bulbs: Looks like an incandescent bulb, consumes as little as an LED. Filament bulbs are based on LED technology: they resemble classic incandescent bulbs but are much more energy-efficient. Unlike other LEDs, filament bulbs have a similar beam characteristic to conventional incandescent filaments, meaning they emit light almost omnidirectionally. The light spectrum of the filament lamp is quite continuous and shows no prominent peaks of individual colors. Furthermore, heat generation is so low that you can easily touch the glass bulb even after prolonged operation.
