IEC/EN 62776 standard – safely connect LED tubes directly to 230 V
IEC EN 62776 defines all technical and safety-related requirements that must be met when replacing double-capped fluorescent lamps (G5 and G13) with LED tubes in existing systems. The standard describes how retrofitting must be carried out correctly, which components need to be decommissioned, and how standards-compliant operation with an LED tube directly connected to 230 V is ensured. For companies, the standard provides a binding framework for continuing to use existing luminaires and fixtures while upgrading to an efficient, low-maintenance, and future-proof LED lighting system.

What does the IEC/EN 62776 standard regulate?
IEC/EN 62776 is the key product safety standard for the 1:1 replacement of T5 and T8 fluorescent tubes with LED tubes using the same bases (G5/G13). It covers the following aspects:
- electrical safety
- interchangeability
- permitted operating conditions
- mandatory temperature range between –20 °C and +60 °C
- test procedures under real operating conditions
Since 1 December 2015, the standard has been mandatory throughout the EU for all T5 and T8 LED retrofit tubes.
Objective of the standard:
The standard ensures that the transition from fluorescent lamps to LED lamps is carried out using safe LED products and under defined replacement conditions.
The standard distinguishes between two product groups:
Double-capped LED retrofit lamp (for CCG/VVG luminaires)
1:1 replacement without modifying the luminaire. The starter is replaced with a dummy, electrically bypassing the CCG/VVG.
- No intervention in the luminaire
- Fast and easy renovation
- Operation directly at 230 V after conversion
Double-capped LED conversion lamp (for ECG luminaires)
In this case, the ECG is converted in accordance with EN standards and the control gear is removed. The conversion must be carried out by a qualified electrician.
- ECG is decommissioned once by a qualified electrician
- Operation directly at 230 V after conversion
Why EVGs should be eliminated – LED tubes connected directly to 230 V
ECGs and CCGs originate from fluorescent lighting technology and are unnecessary for LED systems. They frequently cause malfunctions, energy losses, and failures. In a standards-compliant retrofit, they are bypassed; the LED tube takes over all functions via its integrated driver.
Weak points of external control gear
- switching cycles / flicker
- voltage surges
- uncontrolled start-up sequences
- additional power losses
- high failure rates
ECG conversion according to EN standards for G5 and G13 sockets without control gear
Advantages of direct connection to 230 V
- less electronics → fewer potential failure points
- lamp replacement without a qualified electrician
- no ECG losses → higher efficiency
- flicker-free, stable light
- standards-compliant retrofit according to EN 62776 and preservation of CE conformity
- decades of reliable operation based on an international standard
