See the Difference CRI Makes
Standard CRI 80+Dull, washed-out light
Reds lose their warmth. Skin looks pallid. Artwork loses depth. The room feels lifeless regardless of how many bulbs you use.
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.


Product Features
Description
Description
Soft, even warmth along a mid-length tube, with nothing visible inside. The dimmable 4W Medium Tube LED Bulb E27 Matte Finish delivers 260 lumens of 2700K warm white light through a matte white coating in an E27 fitting, replacing a traditional 25W incandescent with ultra-high colour accuracy. The diffused glow spreads evenly across the full 185mm of the tube without any hotspot or visible internal component. Backed by a 3-year warranty.
The Matte Finish
The matte coating conceals the LED array completely, spreading light across the medium-length tube in a consistent wash without any hotspot or glare. The diffused glow is quieter than the clear glass alternatives in this range: warmth that fills the fitting rather than projecting from it, reading as restful and settled rather than sparkling. Switched off, the smooth white tube looks clean and considered in any open fitting, with none of the visible filament character of the clear or amber variants in this family.
A trailing-edge dimmer lets brightness step back smoothly with flicker-free performance. The 185mm length suits fittings where the compact short tube would look underscaled but the full 290mm of the long porcelain version would be too dramatic.
Where It Belongs
Pendant fittings, open wall sconces, and table lamp designs where a medium-length diffused tube suits the scale of the fitting and a gentle, glare-free glow is preferred over any visible filament detail. In hospitality, boutique hotel corridors and café environments building a calm, understated atmosphere are natural settings. Bedroom and living room pendants where a softly diffused glow suits everyday evening use, nurseries and children's rooms wanting a soft non-distracting light source, and hallway fittings running for long evening hours without glare are practical residential applications. The E27 fits the standard Edison screw socket used in most pendant and lamp fittings.

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 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.
