JOKER - The emergency lighting magazine
Your new reading material about emergency lighting.

With helpful content to standards and regulations, practical tips and impulse contributions.
What’s behind it?
You’re familiar with the Joker in the card pack – it is a trump card that helps the player win because it beats all the others. Not for nothing did we name our trailblazing innovation of 1998 “Joker system”. This world-first made it possible to create the first-ever emergency lighting circuit with three different operation modes (maintained light, switched maintained light and non-maintained light), simplifying installation enormously. This technology has established itself on the market under the term “mixed operation”. The patent – German patent number: DE 19807844, European patent number: EP 0939476 – is one of the most important foundations on which the company’s success is built. That is why we think JOKER is the right name for our magazine.
What do we want to achieve?
With the new magazine, we want to give you practical tips for your day-to-day work and illustrate with concrete examples those system applications that require explanation.
It is intended as a tool for transferring knowledge to all the different sectors involved in emergency lighting – designers, fitters, architects, fire fighters and so on – and to provide stimuli for the industry as a whole. At the same time, we will be using the publication to address topical issues and spark some debates.
