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.

Fiecare achiziție redă vederea

Dulora sprijină cu mândrie Fundația Fred Hollows. Fiecare comandă contribuie la finanțarea operațiilor de cataractă și a programelor de îngrijire a ochilor din Australia. O simplă achiziție a unui bec. Un rezultat care schimbă viața cuiva care nu a putut niciodată să vadă clar.

CRI standard 80+

Lumină ternă, spălăcită

Roșul își pierde căldura. Pielea pare palidă. Operele de artă își pierd profunzimea. Camera pare lipsită de viață, indiferent de numărul de becuri folosite.

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.

Caracteristicile produsului

Strălucire clasică în stil incandescent – blândă, confortabilă și primitoare.
Acuratețe ridicată a culorilor – îmbunătățește tonurile pentru un aspect mai bogat și mai natural.

Descriere

Nu orice tub decorativ are nevoie de o tentă chihlimbarie sau de un model vintage. Becul LED reglabil Medium Tube de 4 W, cu soclu E27 și sticlă transparentă, oferă 470 de lumeni de lumină albă caldă la 2700 K prin sticlă clară, într-un soclu E27, înlocuind un bec incandescent tradițional de 40 W cu o redare ultra-precisă a culorilor. Filamentul simplu, neornamentat, de-a lungul tubului transparent de 185 mm oferă exact căldura și vizibilitatea pe care le-ai aștepta de la un filament expus, fără caracterul vintage suplimentar al variantelor spiralate sau chihlimbarii. Beneficiază de o garanție de 3 ani.

Efectul sticlei transparente

Sticla transparentă menține filamentul simplu vizibil pe întreaga lungime de 185 mm a tubului mediu, oferind o strălucire caldă și direcționată, fără modelul spiralat sau tenta chihlimbarie a gamei vintage. Filamentul neornamentat este o alegere de design în sine: mai curat și mai contemporan decât o spirală în stil retro, potrivit pentru corpuri de iluminat suspendate moderne și instalații minimaliste, unde o sursă mai simplă este alegerea potrivită. Când este stins, tubul pare intenționat, nu decorativ, ceea ce îl recomandă pentru corpuri contemporane în care structura este elementul central, iar becul trebuie să o completeze, nu să concureze cu ea. Un variator de intensitate cu tăiere la capătul fazei permite reducerea lină a luminozității.

Unde se potrivește

Corpuri de iluminat suspendate, aplice de perete și lămpi cu design deschis, unde forma specificată este un bec tubular transparent de lungime medie, iar lumina albă caldă simplă este preferată gamei vintage chihlimbarii. În spații de ospitalitate, în șiruri de corpuri suspendate din cafenele și restaurante, precum și în corpurile moderne de iluminat din camerele de hotel care își doresc un aspect curat și uniform al filamentelor în mai multe corpuri, fără caracter retro, acesta este o alegere naturală. Birourile de acasă, camerele de studiu și corpurile suspendate din living, unde cerința este o sursă de lumină simplă, caldă și fiabilă, precum și aplicele de pe holuri sau scări, care au nevoie de o formă tubulară curată fără complexitatea decorativă a unei spirale, sunt aplicații rezidențiale practice. Soclul E27 se potrivește în dulia standard cu filet Edison, utilizată la majoritatea corpurilor suspendate și a lămpilor.

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.
