How to make light active only in editor?

Our game tone is rather dark, it’s going to be in underground. There will be just couple of small light sources. My problem is that I would like to have some general light that is visible only when designing level and can be easily turned on/off so level designer doesn’t need to focus his eyes too much and trying to see in darkness.

I have been fiddling with various settings, but so far I had no luck to manage that. I would expect that “Actor hidden in game” actually does that, but apparently it’s just about that symbol of it, not actual actor itself.

Is this possible somehow please?

I would click on the light you want to turn off and open the level blueprint. Right click in the level blueprint and you will see “create reference to point light”, or whatever kind of light you are using. Drag off of that and type in destroy actor. link all of that with event begin play. You can click on every light at one time and when you right click it will give you the option to create a reference for all of the lights.

Thank you very much, it works greatly!
