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.

看看 CRI 带来的差异

标准显色指数 CRI 80+

暗淡、褪色的光线

红色失去温暖感。肤色显得苍白。艺术品失去层次感。无论使用多少灯泡，房间都显得毫无生气。

Dulora CRI 97+

Rich, accurate light

Every hue appears exactly as intended. The same room, transformed. Not brighter, but alive. This is what your space was always meant to look like.

描述

这款管状灯泡专为注重光质的场景打造。可调光 4W E27 透明管状 LED 灯泡通过 E27 灯头和透明玻璃，提供 470 流明的 2700K 暖白光，以超高显色准确度替代传统 40W 白炽灯。食物看起来更加新鲜，织物色彩保持真实，肤色呈现温暖自然、更加衬肤的效果，而不会像在较低品质的光线下那样显得失真。提供 3 年质保。

透明玻璃效果

透明玻璃让灯丝沿灯管清晰可见，但这款灯泡真正区别于其他管状灯泡之处，在于光线本身对周围环境的影响。在普通 LED 替代品下可能略显暗淡或偏移的色彩，在这里都能保持完整色调；这种差异在食物准备、纺织和手工制作，以及更关注肤色准确度的更衣区或化妆台等环境中最为明显。

关闭电源后，外露灯丝仍让灯管呈现简洁、精确的外观，适合用于灯泡始终可见的开放式吊灯或电器灯座。配合后沿调光器，亮度可平滑降低，并在每个亮度档位上始终保持稳定的色彩准确度。

适用场景

适合用于需要准确辨别食物色泽的抽油烟机和厨房灯具，需要在人工照明下准确还原肤色的更衣室和化妆区，以及需要准确匹配线材、颜料或织物颜色的艺术、手工和缝纫工作室。在商业环境中，它适用于商用厨房照明、食品展示柜、摄影工作室、餐饮场所备餐区和零售环境；在这些场景中，真实呈现产品色彩是切实需求，而不是次要考量。E27 灯头适配大多数吊灯、电器灯具和台灯所使用的标准爱迪生螺口灯座。

灯泡形状

The description of the general appearance of a lamp/bulb consists of a letter(s) followed by a number. The letter indicates the shape of the bulb, and the number relates to the diameter of the bulb in millimetres. For example, a standard household bulb is the A60. The bulb is "A" shape, and the diameter would be 60 millimetres.

T30
输入电压

This voltage specification denotes the voltage level required for the LED bulb to operate correctly.

220-240 Volt
功率

A rating, expressed in watts, indicates the rate at which a lamp consumes energy. Also known as wattage value.

4W
亮度

A lumen measures the amount of visible light emitted by a source per unit of time. It indicates the brightness or illumination power of lamps and lighting systems.

470 lumens
色温

An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four-digit number followed by (K), such as 2700K. High temperatures indicate white, "cooler" colours, while lower temperatures indicate yellower, "warmer" colours. Some typical Kelvin temperatures are 2700K (warm white) and 4000K (natural white).

2700 Kelvin
显色指数（CRI）

The Colour Rendering Index is an international system that rates a lamp's ability to render objects colours. The higher the CRI (based upon a 0-100 scale), the richer and more accurately the colours appear. CRI differences among lamps are not usually visible unless the difference is more than 3-5 points.

97+
可调光

Indicated whether a product can be dimmed in conjunction with a suitable dimmer control.

Yes, with most incandescent and LED dimmers.
护眼

Eye comfort measures how stable and consistent a bulb's light output is. Even when invisible to the naked eye, flickering light can cause headaches, eye strain, and fatigue, particularly during extended periods of reading, working, or relaxing at home. Dulora's dimmable globes are independently tested by TÜV Rheinland and meet internationally recognised low-flicker standards at full brightness. For the best experience, pair with a quality LED dimmer, as flicker performance can vary depending on the dimmer used.

Low Flicker (Pst LM < 1.0 at full load, TÜV Rheinland tested)
白炽灯等效功率

The wattage value of an incandescent lamp of similar brightness.

25W
玻璃表面处理

Frequently Asked Questions

Why should I choose CRI 95+ LED bulbs over standard CRI 80?

Standard bulbs often make interiors look grey or "muddy" because they lack depth in the colour spectrum. Our CRI 95+ collection provides "True Colour" light that is almost indistinguishable from natural daylight, making your furniture, artwork, and skin tones look vibrant and accurate.

Do these high CRI bulbs have a high R9 value for reds?

Yes, our CRI 95+ range is specifically engineered with high R9 values, which is the specific metric for rendering deep reds. This is essential for bringing out the rich grain in timber flooring and ensuring skin tones look healthy rather than washed out under artificial light.

Are these high-quality LED bulbs flicker-free?

Absolutely. We use advanced constant-current drivers within our bulbs to ensure a flicker-free performance that is gentle on the eyes. This reduces the risk of eye strain and headaches, which are common issues with cheaper, low-quality LED alternatives.

Will these CRI 95+ bulbs work with my existing dimmer switches?

These bulbs are fully dimmable and designed to be compatible with most modern trailing-edge LED dimmers. To ensure the smoothest dimming range without buzzing, we always recommend checking that your dimmer switch is rated for low-wattage LED loads.

Can I use these bulbs in art galleries or high-end retail displays?

Yes, our CRI 95+ collection is the preferred choice for galleries and boutique retail where colour precision is non-negotiable. The high fidelity ensures that products and paintings are viewed exactly as the artist or designer intended, with no artificial colour shifting.
