Atta C35 4W E14 Filament Bulb: Vintage Style Meets LED Technology
The Atta C35 4W E14 is a beautifully crafted LED filament bulb that brings vintage charm to modern lighting. Unlike standard opaque LEDs, filament bulbs feature exposed LED filaments arranged in decorative patterns inside a clear glass envelope.
When illuminated, these filaments glow with a warm, inviting light that mimics the appearance of traditional incandescent bulbs. When off, the bulb’s internal structure adds visual interest to any fixture.
This combination of nostalgic design and contemporary LED technology makes the Atta filament bulb a popular choice for interior designers and homeowners seeking characterful lighting.
Atta C35 4W E14 Filament Bulb: Understanding the Code
The product name contains important specifications that help identify the correct bulb for your needs.
C35 refers to the bulb shape and size. “C” stands for candle or conical shape, and “35” indicates the diameter in millimetres (35mm). This classic candle shape is designed to resemble traditional flame-tip candles.
4W indicates the power consumption is just 4 watts. Despite the low wattage, it produces ample light for decorative and ambient applications.
E14 specifies the base type. E14 is a small Edison screw base, approximately 14mm in diameter, commonly used in smaller light fittings, chandeliers, and decorative lamps throughout Europe and many other regions.
Atta C35 4W E14 Filament Bulb: Light Output and Quality
The Atta C35 4W E14 filament bulb delivers warm, inviting illumination perfect for creating comfortable living spaces.
Light Output: Approximately 400 lumens, equivalent to a traditional 40-watt incandescent bulb . This provides gentle ambient lighting ideal for living rooms, bedrooms, and restaurants.
Color Temperature: Warm white at 2700K, producing a cozy, yellowish glow similar to traditional incandescent lighting . This creates a relaxing atmosphere that flatters skin tones and interior decor.
Beam Angle: 360-degree illumination ensures light radiates in all directions, filling the room evenly without dark spots . This omnidirectional characteristic makes filament bulbs excellent for open fixtures.
Color Rendering: CRI (Color Rendering Index) typically above 80, ensuring colors appear natural and true to life . Good color rendering is essential for spaces where accurate color perception matters.
Atta C35 4W E14 Filament Bulb: Energy Efficiency
Despite its vintage appearance, the Atta filament bulb incorporates advanced LED technology for exceptional energy efficiency.
The 4-watt power consumption represents approximately 90% energy savings compared to a traditional 40-watt incandescent bulb . This significant reduction lowers electricity bills without compromising on light quality.
LED filaments use Chip-on-Glass (COG) technology, where LED chips are mounted directly onto a glass substrate . This allows the filaments to be thin, flexible, and arranged in attractive patterns while maintaining excellent thermal performance.
The efficiency means these bulbs generate minimal heat, making them safer for use in enclosed fixtures and reducing the load on air conditioning in warm weather.
Atta C35 4W E14 Filament Bulb: Applications
The decorative nature of the Atta C35 filament bulb makes it particularly suitable for fixtures where the bulb is visible.
Chandeliers: The candle shape and clear glass enhance traditional and modern chandelier designs, adding elegance and sparkle.
Wall Sconces: Open-fronted sconces allow the bulb’s filament to become part of the decorative scheme.
Pendant Lights: Single or multiple pendants benefit from the vintage aesthetic, creating statement features in kitchens and dining areas.
Table and Floor Lamps: Lamps with clear glass shades or open designs showcase the bulb’s character.
Bathroom Vanities: Multiple bulbs above mirrors provide functional lighting with decorative appeal.
Commercial Spaces: Restaurants, cafes, bars, and hotels use filament bulbs to create welcoming, atmospheric environments .
Atta C35 4W E14 Filament Bulb: Dimmability
Many C35 filament bulbs are available with dimming functionality, offering greater control over lighting levels .
Dimmable versions allow adjustment of brightness from 0% to 100%, enabling you to create the perfect ambiance for any occasion. From bright illumination for tasks to soft, romantic lighting for evenings, the flexibility enhances any space.
It is essential to use compatible dimmer switches designed specifically for LED loads. Traditional dimmers designed for incandescent bulbs may cause flickering or limited dimming range.
If dimming is not required, non-dimmable versions offer a cost-effective alternative while maintaining the same aesthetic appeal .
