Keep The Light On

A Ghostlight burns in empty theatres as a beacon against the dark and as a promise to soon retake the stage.

We will all return to the stage. Until then, GLP will keep its own Ghostlight burning for all of you.

About the Ghostlight.


Theatrical folk are a superstitious lot. Wishing actors a broken leg (don't ever tell them "good luck") or avoiding whistling backstage are just a sampling of the multitude of time-honored theatre traditions.

But the Ghostlight , a single bulb left burning whenever a theatre is dark, is one superstition that's also proven itself a modern theatre necessity.

About Ghosts and Safety

For the spirits of the theatre a Ghostlight should always burn in an empty theatre at night. This Ghostlight serves to illuminate the stage so that the theatre spirits can do their performances and bring their long gone great moments back to the stage. - This shall prevent the theatre spirits from disturbing regular performances with their pranks.

But there is also a little less romantic explanation for the ghostlight: Safety.
That light ensures that no one takes an accidental tumble off the stage into the orchestra pit when working late.

But the Ghostlight also sets a sign: We'll be back!

Our Ghostlight stands for the promise to retake the stages again. So that we and the whole event industry can again do what is our passion and what our hearts beat for as soon as possible!

And GLPs hearts beat for: LICHT!


It is hard for me to put into words what I am feeling after countless conversations with friends, business partners and employees.

How I would have liked to meet you at one of the canceled shows instead of having to write these lines.

But one thing is clear: the GLP family is standing together and we will also face this global crisis together. Even if it is currently still very difficult to predict how this "dynamic situation" will develop, we have implemented all the necessary measures to continue to be there for you and to maintain our service level. In the past few days we have focused on ensuring consistently good accessibility and making almost all of our employees fully capable of working from home. The expression “digitalisation” has become reality almost overnight.

No matter what restrictions may come next: we will be with you for as long as possible.

I personally wish for all of us that we will remain hopeful and that we will rise above the bitter situations that are probably unavoidable. I hope and trust that we will be helped by the strong sense of community that I feel everywhere.

GLP announces 12-Month

Global Extension of Product Warranties

GLP lives up to #KeepTheLightOn

German based automated lighting manufacturer GLP (German Light Products), has taken an unprecedented step in its determination to support customers during the ongoing COVID-19 pandemic.

Today it announced an automatic 12-month product warranty extension for any GLP product whose original warranty was due to expire between April 1, 2020 and March 31, 2021. The company has been using the hashtag #keepthelighton (and #KTLO) since the beginning of the pandemic, and is living up to this motto by taking this important decision.

“GLP recognises and understands that the vast majority of our products have been sitting idle for many months, and will continue to do so in anticipation of their next call to duty,” declared Udo Künzler, managing director of GLP GmbH. “Therefore, we wanted to make a full show of support to our loyal customers, whose livelihoods depend on those fixtures being used.”

The year-long extension is being applied to every product within the GLP portfolio. Furthermore, in order to simplify the process, this extension has already been registered through every GLP office and those of their distributors. Customers need take no action in order to ensure that the extension will be applied – it’s already been done.

“As a global manufacturer, supporting our customers and our products around the world is of paramount importance to us,” continued Udo Künzler. “Whilst the pandemic continues to wreak havoc amongst our users, we wanted to bring a level of reassurance that they are not going to lose out on warranty status through the time that products are not being actively used.”

Any questions regarding this policy should be directed to the local GLP office, or GLP distributor.
