What are the differences between LED tubes?

LED tubes are great to plug & play alternatives to old fluorescent tubes. These innovative solutions offer significant savings on energy costs, which can reach up to 70% on most occasions. However, due to the vast supply of LED tubes, finding the solution that is right for us can sometimes be difficult. But reading this short blog, you can easily find the right LED tube.

What are the differences between T8 and T5 tubes?

Crest LED offers LED alternatives for both T8 (TL-D) and T5 (TL5) tubes. The main differences between these two types of tubes are the diameter and the attachment. The T8 tubes have a diameter of 28 mm and a G13 attachment, with the feet, 13 mm apart. The T5 tubes instead have a diameter of 16 mm and a G5 attachment, with a distance between the two pins of 5 mm.

What kind of driver do I need?

Conventional or electromagnetic ballast (EM)

This type of driver is commonly found in old luminaires equipped with a conventional starter. It is very easy to recognize as it produces a slight but constant hum. Furthermore, when the tubes are turned on, the light emitted suffers an initial flicker. Tubes compatible with conventional transformer (EM) can be distinguished by the presence of a single blue ring at the end of the tube. When replacing the old tube to switch to the LED, it is necessary to remove the old starter and install the specific one for LED solutions.

Electronic ballast (HF)

This transformer technology does not require the use of a starter. All LED tubes compatible with light fixtures equipped with electronic drivers have a double blue ring at one end. It is important to remember that all T5 tubes are compatible only with electric drivers (HF).

Universal ballast (UN)

The universal tubes are compatible with all types of transformers, thanks to the modern integrated multi-function technology. Universal LED tubes (UN) can be applied to luminaires with conventional (EM), electronic (HF) or directly to the mains voltage. This type of LED tubes is characterized by 3 blue rings at the end of the tube and is the ideal solution when using different types of transformers.
