Descripción
Una bombilla GLS con algo que contemplar. La bombilla LED GLS regulable de 4 W con filamento Quad Loop B22 en Extra Warm ofrece 240 lúmenes de luz extra cálida de 2200 K con una forma de bombilla clásica equipada con un filamento decorativo de cuatro bucles, sustituyendo a una bombilla incandescente tradicional de 25 W con una precisión cromática ultraalta y un funcionamiento sin parpadeos con reguladores de corte de fase descendente. Cuenta con una garantía de 3 años.
El efecto del vidrio transparente
El filamento de cuatro bucles es el elemento distintivo de esta bombilla. Mientras que una GLS transparente estándar presenta una disposición lineal de segmentos de filamento, el diseño Quad Loop organiza cuatro espirales luminosas dentro del vidrio transparente, creando una fuente de luz más compleja y visualmente interesante que se aprecia claramente desde cualquier ángulo. Cuando está encendida, las cuatro espirales brillan juntas con una intensa calidez de 2200 K, y cada una contribuye a una calidad estratificada y tridimensional que un solo filamento no puede reproducir. Con niveles bajos de regulación, los bucles individuales siguen diferenciándose y el carácter ámbar de la luz se intensifica, por lo que esta bombilla aprovecha mejor un regulador que un filamento estándar.
Apagada, la disposición de cuatro bucles permanece claramente visible dentro del vidrio con su característico patrón de cuatro puntos, un detalle refinado que luce bien en cualquier luminaria abierta o portalámparas de bayoneta expuesto donde la bombilla esté siempre a la vista.
Dónde encaja
La GLS B22 de 4 W con filamento Quad Loop en Extra Warm es ideal para luminarias abiertas en las que la bombilla queda visible y se puede apreciar el detalle del filamento: lámparas colgantes sobre mesas de comedor, lámparas de pie con pantallas abiertas o de estructura de alambre, luminarias con portalámparas expuesto en salones y recibidores, y accesorios de estilo vintage en los que la complejidad del Quad Loop aporta interés visual con cualquier nivel de brillo. En entornos de hostelería, es adecuada para vinotecas, lámparas colgantes de cafeterías, comedores íntimos de restaurantes y habitaciones de hoteles boutique, donde la profundidad extra cálida de 2200 K y el carácter decorativo forman parte del concepto. El casquillo de bayoneta B22 es compatible con uno de los tipos de portalámparas más utilizados en instalaciones residenciales y comerciales.

Frequently Asked Questions
Frequently Asked Questions
How bright are Dulora bulbs?
LED brightness is measured in lumens, not watts. Here's a quick conversion guide:
- 2-3W LED ≈ 25W incandescent (200-300 lumens)
- 4-5W LED ≈ 40W incandescent (400-500 lumens)
- 6-8W LED ≈ 60W incandescent (650-800 lumens)
- 7.5-10W LED ≈ 75-100W incandescent (900-1200 lumens)
- 11-12W LED ≈ 100-125W incandescent (1300-1500 lumens)
All Dulora product pages list wattage and lumen output so you can choose the perfect brightness for your needs.
What is the lifespan of Dulora bulbs?
Dulora bulbs are designed for over 25,000 hours of use. If you use your light for an average of 3 hours per day, your LED bulb could last over 22 years. This exceptional longevity significantly reduces the frequency of replacements compared to traditional incandescent bulbs, which typically last only 1,000-2,000 hours. Note that all LED bulbs' light output gradually decreases over time, a phenomenon known as lumen depreciation.
Are Dulora bulbs dimmable?
Yes, most Dulora bulbs are dimmable, allowing you to create the perfect ambience for any occasion. Look for the "dimmable" specification on the product page. For optimal performance, we recommend using LED-compatible dimmers. Some older dimmer switches may cause flickering or buzzing with LED bulbs. If you experience any issues, please contact our customer support team for assistance.
What is colour temperature, and which should I choose?
Colour temperature refers to the warmth or coolness of light, measured in Kelvins (K):
- Ultra & Extra Warm (2000K-2200K): This calming light creates a relaxing ambiance, similar to the warm glow of candlelight.
- This calming light gives off a warm glow, similar to candlelight. However, because it is such a soft light, it may not be suitable for activities that require focus, such as reading.
- Warm White (2700K-3000K): This colour creates a cozy, inviting atmosphere similar to traditional incandescent bulbs. It is ideal for living rooms, bedrooms, and dining areas.
- Natural White (3500K-4000K): Provides a balanced, neutral light perfect for kitchens, offices, and workspaces.
- Cool White (5000K-6500K): This colour delivers a crisp, energising light similar to daylight. It is best for task lighting, garages, and areas requiring detailed visibility.
Choose based on the mood you want to create and the purpose of the space.
Are Dulora bulbs compatible with my existing fixtures?
Dulora offer bulbs in all standard base types, ensuring compatibility with most fixtures. Common bases include:
- E27/ES: Standard Edison Screw, the most common base type (27mm diameter)
- B22/BC: Bayonet Cap, standard in many regions (22mm diameter)
- E14/SES: Small Edison Screw, used in chandeliers and smaller fixtures (14mm diameter)
- B15/SBC: Small Bayonet Cap, used in smaller fixtures (15mm diameter)
- E12/SES: Mini Edison Screw, used for chandeliers and small fixtures from the US (12mm diameter)
Check your existing bulb's base type and match it with the corresponding Dulora product. If unsure, take a photo of your current bulb base and contact our customer service team for assistance.
Can Dulora bulbs be used in enclosed fixtures?
Some Dulora bulbs can be used in enclosed fixtures, but not all. Look for the "enclosed fixture compatible" specification on the product page. Enclosed fixtures trap heat, which can shorten LED lifespan if the bulb isn't designed for such applications. Our enclosed fixture-compatible bulbs feature enhanced heat dissipation technology to maintain performance and longevity even in enclosed environments. For fixtures without proper ventilation, we recommend choosing bulbs specifically rated for enclosed use.
What is the difference between clear, frost, opal, and porcelain LED bulbs?
- Clear LED bulbs have a transparent glass covering that showcases the filament inside, creating a decorative, vintage appearance. They produce more directional light and create beautiful shadow patterns.
- Frost, opal, and porcelain LED bulbs diffuse light, reducing glare and distributing illumination evenly. These bulbs are ideal for ambient lighting and minimising shadows when fabric or glass shades are used. Frosted bulbs allow good light transmission but with slightly visible LED filaments. Opal and porcelain bulbs provide uniform light diffusion and better LED concealment. Opal bulbs have a shiny finish, while porcelain bulbs have a matte finish.
Choose clear bulbs for decorative fixtures where the bulb is visible and frosted, opal or porcelain bulbs for everyday lighting where comfort and light distribution are priorities.
How much energy do Dulora bulbs save compared to traditional bulbs?
Dulora bulbs use up to 90% less energy than traditional incandescent bulbs while providing the same brightness level. For example, a 6.5W GLS LED bulb produces the same light as a 60W incandescent bulb. This significant energy reduction translates to lower electricity bills and a smaller carbon footprint. Over the bulb's lifetime, you can save hundreds of dollars in energy costs per bulb.
What is your warranty policy?
Dulora bulbs come with a comprehensive warranty against manufacturing defects. Most of our products carry a 2-year warranty, while premium lines may offer extended 3 to 5-year coverage. If your product fails during the warranty period under regular use, we'll replace it free of charge. Simply contact our customer service team with your order number and a description of the issue. Our no-quibble guarantee ensures a hassle-free experience if you encounter any problems.
