Fluorescent tubes are a type of light bulb or lamp that use fluorescence to produce visible light. It is important to remember that fluorescent tube lights require a ballast to supply enough voltage to start the lamp and then to regulate the supply to operate the light safely. To learn more about fluorescent lights, please see our [fluorescent tubes guide](/web/content/discovery/ideas-and-advice/fluorescent-tubes-guide).

At RS, we have fluorescent tube lights in straight and circular variations that are available in a range of lengths, diameters and colour tones. Our curated range features products from industry-leading brands including Osram, GE, Sylvania and our own RS PRO.

### Standard Fluorescent Tubes Sizes:

Fluorescent tubes are widely available in standard sizes known as T2, T4, T5, T8 and T12, with these sizes referring to the diameter of the bulb. Each standard size is available in different wattages, colours and lengths to suit every application.

- T2 fluorescent tubes have a 7 mm diameter and are used within display cabinets for retail applications or in the home.
- T4 fluorescent tubes feature a 12mm diameter and are most commonly used for kitchen worktops.
- T5 fluorescent tubes have a 16 mm diameter and are used within offices, warehouses and kitchens. T5 tubes have a distinct advantage as they can be continuously installed in series.
- T8 fluorescent tubes have a diameter of 26mm and are suited to larger environments and would typically be found in supermarkets, warehouses and hospitals.

### Why should I pick a fluorescent tube?
- Fluorescent tubes are a cheap and efficient way of generating light. Fluorescent light fixtures can cost more to install than incandescent options, however, they are more energy-efficient. They use less energy and are more cost-efficient to run.
- When choosing a fluorescent tube, you must consider the luminosity (measured in lumens - lm) each bulb offers. The higher the number of lumens, the brighter your bulb will be.
- Another benefit to choosing a fluorescent tube is the distribution of light, as fluorescent tubes diffuse light evenly.

### Warning:

If a lamp breaks, you should ventilate the room for 30 minutes before removing the parts (preferably with gloves on). The parts should be taken for recycling at your local waste facility.



Linear fluorescent tubes are types of gas-discharge lamps that use electricity, mercury, inert gases and a phosphorus coating to produce a visible light.

Circular Fluorescent Tubes | RS

Circular fluorescent tubes are a popular choice for lighting designers, particularly in architectural and ceiling light fittings. They are an energy saving and compact light source designed for shallow and slender recessed ceiling and wall-mounted light fixtures, offering the same benefits as linear fluorescent tubes in a more compact, circular shape as opposed to a longer strip light that it may not be possible to accommodate in the intended space.Circular fluorescent tubes are popular for the particular aesthetic advantages they can provide. With an average life of around 10000 hours, it is a long time before your fluorescent bulbs will need replacing. They are often used in spaces in which flush light fittings are often found, such as bathrooms and kitchens, and other spaces in which a protrusive light fitting may post a health and safety risk, such as in busy corridors or areas of high foot traffic. These light fittings are also commonly as outdoor and security lights as their long life ensures they will last for a long time.Being a fluorescent light source, these lamps are energy efficient and cost effective when compared to a conventional lighting solution.
