4W and 8W Filament Bulbs

4W and 8W filament bulbs utilize LED technology. Their design mimics the shape of traditional incandescent filaments, creating a unique decorative effect. These bulbs typically offer a warm color temperature of around 2700K, creating a soft, atmospheric light suitable for residential or commercial spaces. Encased in a transparent or translucent glass shell, the LED filaments within deliver 360-degree illumination, ensuring uniform light distribution. Their color rendering index typically exceeds 80, effectively reproducing the colors of objects. The 4W model delivers approximately 380 lumens, while the 8W model reaches 760 lumens. Users can choose the appropriate wattage based on their lighting needs. These bulbs typically feature standard E27 or B22 bases, compatible with most conventional fixtures and offering easy installation. Their lifespan typically ranges from 15,000 to 30,000 hours.
