Two different versions of LED lamps in linear tubes can be found in the market: retrofit and
conversion.
•
Retrofit LED lamps are lamps which can be inserted in an existing luminaire without modification. This operation has the character of maintenance.
•
A conversion LED unit is a lamp which requires changes in the luminaire components. In
this case safety requirements have to be checked in a different way taking into consideration thermal and electrical behaviour of the new components, and the possibility that the user will insert again a tubular fluorescent lamp.

Led light tubes are the first and so far the only LED lamps format, which has received international harmonized standard. IEC approved E N 62776 – the standard for many years after twisting in mid-December 2014.

Standardization allows for traditional T8 fluorescent tubes are compatible with LED light tubes. In addition, the standard defines the characteristics of LED light tube, so that they are compatible with each other.

The new standard of the old fluorescent lighting tubes can be exchanged with one of led light tube. The standard also defines the characteristics required of a light pipe, such as mechanical strength, physical dimensions and electrical characteristics.
