What does T8 mean in fluorescent lighting?

This name has to do with the diameter of the tube, which is 8/8 inch (28 millimetres). Another important feature of fluorescent lighting in T8 format is the G13 fitting, which consists of two pins 13 millimetres apart. Hence the name G13.

What is the difference between T8 and T5 tubes?

The biggest technical difference is in the diameter. You can see from this that T5 tubes are narrower, with a diameter of 5/8 inch (about 1.5 centimetres), compared to the 8/8 inch of the T8 tube. There are also differences in the length of these two types of fluorescent lighting. The most common sizes of T8 tubes are 60cm, 90cm, 120cm and 150cm. In T5 tubes are 55 cm, 85 cm, 115 cm and 145 cm. Furthermore, T8 fluorescent tubes are suitable for both conventional (with starter) and electronic ballasts (without starter), while the T5 tubes work only on electronic ballasts.

Can you still buy conventional fluorescent tubes?

Yes, TL lighting is still available on our website. However, all fluorescent tubes are being phased out. For T8 fluorescent tubes, it applies that they may no longer be produced from September 2023. From that date, these fluorescent lights will therefore be available at Lampdirect as long as stocks last.

What is the function of a starter in fluorescent tubes and when do I need it?

A starter can be seen as a kind of 'starter motor', which ensures that a T8 tube lights up when the light switch is turned on. At the bottom of the starter there are two pins. As soon as more than 200 Volt is applied, a kind of gas discharge is created in the starter, which works as a kind of lighter for the fluorescent tube. You need a starter when your T8 tube works on a conventional ballast. You can check this by checking whether your current fluorescent tube has a starter. On the other hand, it is always indicated on the ballast what type it is. If it says HF, it is an electronic ballast and you do not need a starter. Is it marked EM/AC/Mains on the ballast, then it is a conventional ballast and you will need a starter. You can use a Philips S2 starter for TL lamps of 18W (60cm) and the Philips S10 starter for all other wattages and lengths.

Why do fluorescent tubes flicker when starting up?

This is because the starter and the conventional ballast need a few seconds to get the light from the fluorescent tube to full strength when starting up. Does the light blink continuously? Then the ballast (or some parts of it) has become too hot and you should replace this part. Tip: LED tubes are flicker free and give 100% light instantly. This means that you will not be bothered by your eyes or suffer from headaches/migraines.

How long does a T8 (TL-D) tube last on average?

On average, T8 fluorescent lamps last about 10,000 hours. Converted this is about 3 years, when the light is on for 60 hours a week. A life of 10,000 hours seems a lot, but compared to LED fluorescent tubes it is not much, because these now last more than 60,000 hours!

Are T8 tubes economical?

In general, T8 fluorescent lighting is not very economical. This is primarily because the light shines 360 degrees around. This is not very efficient, because lighting the ceiling is not necessary. This means that during its lifetime unnecessary power is lost. Furthermore, there is mercury in fluorescent tubes, which is bad for the environment. When a fluorescent tube breaks, toxic mercury vapours can be released.

Where can old fluorescent tubes be handed in?

You can always hand in your old or superfluous fluorescent lighting at the recycling centre in your town/city. Almost all raw materials of a fluorescent tube can be reused. Also, the mercury that is still in the lamp is processed in a responsible and environmentally friendly way. Talking about sustainability: the best alternative to fluorescent tubes is LED tubes!

Is it easy to replace a T8 fluorescent tube with LED?

Absolutely! LED fluorescent tubes are available in the same sizes and are also suitable for both conventional and electronic ballasts. Would you like to switch from fluorescent tubes to LED? Check the size of your current fluorescent lamp and what ballast it works on. When it comes to a LED tube for a conventional ballast, we always deliver a LED starter with your new product! The biggest advantages of LED fluorescent lighting are:

  • An energy saving of over 70%
  • LED fluorescent tubes last 5 times longer on average
  • Less costs for maintenance & replacement
  • More efficient and narrower degree beam
  • No start up time and flicker free 
  • Instant 100% light
  • Better for the environment: less CO2 emissions
  • Contains no toxic substances and is not fragile

Is it better to replace a complete fluorescent fixture or just the individual fluorescent tubes?

We recommend replacing the entire fixture with an energy-efficient LED variant. The best example is the installation of a LED panel (60x60cm, 30x120cm). If you prefer to replace only the fluorescent tubes for LED tubes, you can of course do that too. When you replace the entire fixture for a LED fixture, you have the advantage that you have replaced everything at once. Suppose you leave your old fixture hanging and it breaks down after some time, then you will still have to buy a new one.
