What does T4 mean in fluorescent tube?

Fluorescent tubes come in a range of different sizes, that are distinguished by the ‘T number’. There are 4 main types of fluorescent tubes that you can use to brighten your environment, these are T2, T4, T5 and T8. The difference between these is the diameter of each tube. In this case, the T4 in fluorescent tubes means that they have a diameter of 13mm. Just because they have a standard diameter, doesn’t mean that they also have a standard length. T4 fluorescent tubes can come in a range of different lengths, and still be known as T4. If you don’t think that a 13mm diameter will work in your application you can choose one of the different sizes, all of which we stock at BLT Direct. If you want a smaller diameter, you can choose a T2 tube, or if you would prefer a light fitting with a wider diameter, you can choose a T5 or T8 tube which are 15mm and 26mm respectively.

Are fluorescent tubes being phased out?

Recent policies have outlined the phasing out of fluorescent lighting, this started with the ban on halogen lights that begins in September 2021. This will be closely followed by a gradual reduction in the production of fluorescent lighting through 2021 and 2022. Fluorescent lights are being phased out in favour of more energy-efficient alternatives such as LED lights. By phasing out these products, the government hopes to cut down on emissions and save consumers on their energy bills. You will notice fluorescent tubes starting to be replaced by LED tubes in the future as they are long-lasting and require a lot less energy to emit light. LED is already quite a popular choice among consumers due to the lower costs it takes them to run and their positive impact on the environment. No matter if you choose to stick with your T4 fluorescent tube lights for now, or decide to switch to LED options, you’ll find a complete and comprehensive collection of products at BLT Direct that are high-quality and affordable.

Are T4 and T5 bulbs interchangeable?

Unfortunately, T4 and T5 fluorescent bulbs are not interchangeable due to the difference in thickness. T4 tubes are 13mm wide, and T5 tubes are 15mm wide, they also require different wattages to power and emit light. There are also many different brands of fluorescent tubes that may offer different sizes and shapes. At BLT Direct, we sell a range of T4 and T5 fluorescent tubes that are fit for any space. So even though you can’t use them interchangeably, you still have plenty of choices.

What length is a T4 fluorescent tube?

At BLT Direct we have a wide range of T4 fluorescent lights in several different sizes to meet all of our customer’s needs. Our lengths start from 218mm to fit small areas like cabinets and workstations, all the way up to 747mm which are perfect for installing in larger rooms and spaces. When browsing our selection of T4 tubes, if you know what size you require, you can filter the search results by length to make sure you’re selecting the correct T4 tube light for your intended purpose.

Can you replace T4 fluorescent tubes with LEDs?

If you’re currently using fluorescent tubes in your home or office, you can switch to LED lights if you’d prefer. To do this, you will have to replace the whole fitting as LED T4 tubes are not available to purchase. You will need to check the length of your space and find a similar size slimline small LED fitting to put in its place. If you’re unsure of the fitting you need to replace your T4 tubes, please get in touch with a member of our customer service team.
