Standard CRI 80+Reds lose their warmth. Skin looks pallid. Artwork loses depth. The room feels lifeless regardless of how many bulbs you use.
Dulora CRI 90+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.

Not every decorative tube needs an amber tint or a vintage pattern. The dimmable 4W Medium Tube LED Bulb E27 Clear delivers 470 lumens of 2700K warm white light through clear glass in an E27 fitting, replacing a traditional 40W incandescent with ultra-high colour accuracy. The plain, unembellished filament along a 185mm clear tube gives exactly the warmth and visibility you'd want from an exposed filament, without the added vintage character of the spiral or amber variants. Backed by a 3-year warranty.
The Clear Glass Effect
Clear glass keeps the plain filament visible along the full 185mm of the medium tube, giving a warm, directional glow without the spiral pattern or amber tint of the vintage family. The unadorned filament is its own kind of design choice: cleaner and more contemporary than a period-styles coil, at home in modern pendant designs and minimalist fixtures where a simpler source is the right call. Switched off, the tube looks deliberate rather than decorative, which suits contemporary fittings where the hardware is the statement and the bulb is meant to complement rather than compete. A trailing-edge dimmer lets brightness pull back smoothly.
Where It Belongs
Pendant fittings, wall sconces, and open lamp designs where a clear tubular bulb of medium length is the specified shape and a plain warm white is preferred over the amber vintage range. In hospitality, café and restaurant pendant runs and modern hotel room fixtures wanting a clean, consistent filament look across multiple fittings without period character are a natural setting. Home offices, studies, and living room pendants where a simple, warm, dependable light source is the brief, and hallway or stairway sconces wanting a clean tubular shape without the decorative complexity of a spiral, are practical residential applications. The E27 fits the standard Edison screw socket used in most pendant and lamp fittings.
LED brightness is measured in lumens, not watts. Here's a quick conversion guide:
All Dulora product pages list wattage and lumen output so you can choose the perfect brightness for your needs.
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.
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.
Colour temperature refers to the warmth or coolness of light, measured in Kelvins (K):
Choose based on the mood you want to create and the purpose of the space.
Dulora offer bulbs in all standard base types, ensuring compatibility with most fixtures. Common bases include:
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.
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.
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.
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.
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.
