Linear by Design

The tubular form brings a clean, architectural quality to spaces that demand something beyond the ordinary globe. Elongated, precise, and visually distinctive, it works as a statement piece in bare filament pendants, bathroom mirror bars, and any fitting where the bulb itself is part of the composition.

Where It Belongs

Run three tubular bulbs above a bathroom mirror and the room shifts from functional to considered in a single decision. Line them above a kitchen benchtop or hang a single long tube in a narrow corridor and the effect is the same: clean, architectural, deliberate. Interior designers and hospitality fit-out teams specify the tubular form because it brings a graphic quality to a space that rounder bulbs cannot. It is lighting that communicates that someone thought carefully about every detail.

Sehen Sie den Unterschied, den der CRI macht

Standard CRI 80+

Trübes, ausgewaschenes Licht

Rottöne verlieren ihre Wärme. Die Haut wirkt blass. Kunstwerke verlieren an Tiefe. Der Raum wirkt leblos, ganz gleich, wie viele Glühbirnen Sie verwenden.

Dulora CRI 90+

Noticeably better light

Colours come back to life. Reds stay warm, skin tones look natural, and surfaces take on the depth and texture they were always meant to have. A significant step above what most homes and venues settle for.

Beschreibung

Einige Fassungen benötigen eine Glühbirne mit genügend Volumen, um sich gegenüber der sie umgebenden Leuchte zu behaupten. Die dimmbare 4-W-Vintage-Spiral-LED-Röhrenlampe erzeugt 200 Lumen ultrawarmes Licht mit 2000 K durch bernsteinfarbenes Glas in einer E27-Fassung. Sie ersetzt eine herkömmliche 25-W-Glühlampe und bietet eine besonders hohe Farbwiedergabe. Das breitere Röhrenprofil gibt dem bernsteinfarbenen Glas mehr Raum für den Spiralglühfaden und erzeugt ein tieferes, markanteres bernsteinfarbenes Leuchten als die schlankeren Röhrenvarianten dieser Serie. Mit 3 Jahren Garantie.

Der Bernsteineffekt

Der Spiralglühfaden füllt die breitere Röhre mit einem bernsteinfarbenen Leuchten, das optisch stärker wirkt als bei der schlankeren Röhrenfamilie: eine breitere, reichhaltigere Ausstrahlung kerzenwarmer Helligkeit statt einer schmalen Lichtlinie. Das bernsteinfarbene Glas vertieft den Farbton zusätzlich und erzeugt eine intime Wärme, die satter wirkt als gewöhnliches Warmweiß. Im ausgeschalteten Zustand verleiht das breitere Profil der Lampe ein robusteres, markanteres Erscheinungsbild als den schlankeren Varianten. Das ist besonders bei schwereren Pendelleuchten nützlich, bei denen die Glühbirne den sichtbaren Raum der sie umgebenden Leuchte ausfüllen soll. Ein Phasenabschnittdimmer ermöglicht es, die Wärme bei niedrigeren Einstellungen zu intensivieren.

Der richtige Einsatzort

Markante Pendelleuchten, Leuchten mit sichtbarer Glühbirne und dekorative Wandleuchten, bei denen die Glühbirne mehr optische Präsenz benötigt, als die schlankere Röhrenserie bietet. Restaurants, Bars und Loungebereiche, die mit sichtbaren Glühbirnen eine warme, intime Atmosphäre schaffen, eignen sich ebenso wie Hotelzimmer und Leseecken, in denen die breitere, markantere Form zu einer schwereren Leuchte passt. Zu Hause profitieren Pendelleuchten über einer Kücheninsel oder einem Esstisch, bei denen die Glühbirne selbst die Blicke auf sich ziehen soll, von der zusätzlichen optischen Präsenz. Im Einzelhandel ist sie eine praktische Wahl für Ausstattungen, bei denen eine markantere Design-Glühbirne wichtige Leuchten von einer Reihe benachbarter, schlankerer Röhrenvarianten abheben soll. Die E27 passt in eine standardmäßige Edison-Schraubfassung.

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 countries do you ship to?

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.
