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
The right shape opens up fittings that a standard globe will never fit. The dimmable 4W Tubular LED Bulb E14 delivers 400 lumens of 2700K warm white light through clear glass, replacing a traditional 40W incandescent with ultra-high colour accuracy and smooth, flicker-free performance on a trailing-edge dimmer. It brings the same warmth and colour quality to E14 fittings that most LED options simply won't reach. Backed by a 3-year warranty.
The Clear Glass Effect
Clear glass keeps the compact filament visible along the full length of the tube, throwing a warm, even glow in all directions rather than from a single concentrated point. The narrow profile opens up appliance housings and compact decorative sockets that a rounded bulb shape couldn't enter, and the exposed filament still gives the fitting a neat, deliberate appearance even in open housings where the bulb is always on show. Switched off, the unlit filament reads as finished rather than blank, which matters in appliance housings and open decorative sockets where the bulb is visible around the clock.
Dimmed on a trailing-edge dimmer, the warm golden glow steps back smoothly without any flicker, useful in appliance sockets and compact bedside fittings where full output isn't needed after dark.
Where It Belongs
Range hoods, refrigerator interiors, under-bench appliance housings, sewing machines, and compact laundry fittings where the E14 socket and slim profile are specified. In residential use, slim decorative wall sconces, picture lights, and narrow pendant fittings where a rounded bulb would be too wide for the housing are a natural fit. Commercially, it suits food display cabinets, commercial kitchen extraction units, and compact hospitality fittings that need warm, colour-accurate light in a smaller, slimmer format than a standard bulb allows. The E14 fits the small Edison screw socket common in compact appliances and decorative fittings across all markets.

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.
