I've created a lightchain. For that lightchain I need a point light at every "bulb", as an emitting material is too weak of a lightsource. To achieve this I have created an array of planes that follows the curve of said lightchain.They are within the lightbulbs and they are hidden as shown in the instancing tab of the screenshot. Each plane instances a single point light.
The problem is, that the original point light can not be hidden in the render, without the instanced lights also being hidden. 
The only way I can get this to work as I want it to, is in the viewport (render preview). By simply hiding the original light in the outliner. Trying to do this in the render disables not only it, but also every instanced light. Meaning either all of them, including the origin, or none of them are shown in the render.
I can not move the original light, as that changes the position of the instanced lights. How do I fix this? The only other way I came up with is to make the instances real just before rendering, and then hide the original lamp, but that is more of a workaround than a solution to the problem.

1$\begingroup$ Hello :). Just place the original light into a separate collection which you then disable (uncheck the box). $\endgroup$– jachym michalApr 12, 2021 at 15:34

$\begingroup$ did you ever try to use emit material with strength 100 and set check to bloom? If this is not light enough i cannot help you.... $\endgroup$– ChrisApr 12, 2021 at 15:35

$\begingroup$ Unclamping indirect light should make emissive materials better, I think $\endgroup$– Allen SimpsonApr 12, 2021 at 15:39

$\begingroup$ @Jachym Michal I tried putting it in a seperate collection, but that just disables all the lights. $\endgroup$– PoppiApr 12, 2021 at 15:45

$\begingroup$ @Chris As far as I know bloom isn't available in cycles, right? only through glare in the compositor. $\endgroup$– PoppiApr 12, 2021 at 15:48

I've found the solution for this. Move the origin of the parent object where you instanced the light. This way the original light will move following the origin of the parent but the instanced light will stay in place.
