Which? tests revealed a problem with Verbatim's Classic LEDs

LED light bulb manufacturer Verbatim (owned by the Mitsubishi Group) has withdrawn stock of its Classic A 6W and 9W LED light bulbs after Which? tests revealed that some bulbs failed to conform to EU safety regulations.

In our tests, the Classic GLS LED light bulbs failed an electrical strength test that forms part of the European standard for electrical safety. 

This means that the LED light bulbs pose a slightly increased risk of electric shock under certain conditions.

Verbatim acts on Which? LED light bulb safety findings

We notified Verbatim of this result immediately and asked it to explain our findings. We also notified Trading Standards. 

As a result, Verbatim has conducted an internal investigation and made a number of changes, including:

• withdrawing and destroying affected stock across Europe

• making improvements to the design of the light bulb

• introducing more stringent quality control processes and additional electrical strength testing

• adding extra safety advice and instructions on packaging.

Verbatim Quality Manager, Ian Rainsford, said: 'While the vast majority of tested lamps were fully compliant with EN 62560: 2013 and EN 60598-1 :2008 norms, a very small number of lamps were not. 

'We do not consider any lamps to present a danger to users. However, if they wish to return them to us, we will of course replace them.'

Best Buy LED lights

We think this is a great result for consumers, and we’re pleased that Verbatim has taken our findings seriously and been swift to act, withdrawing affected stock and taking steps to prevent a reoccurrence.

Our stringent lab tests check every light bulb for safety, including risk of electric shock and electrical strength (how resistant the bulb is to things like power surges).

We also check if bulbs live up to their claims for brightness, colour temperature and lifetime, so you aren’t left disappointed by a dud, or have to traipse back to the shops earlier than you expected.
