Saving Mesh Lights As A Light Preset

Is there a way to save mesh lights as a Light Preset? it keeps saying a light must be selected in scene. I made sure it had luminance, was set up, etc. Saving it as a scene subset didn't work.

No, but Scene Subset (with the emitting objects) should work - what failed when you tried it? If you want to save a preset for the lighting without saving the objects then a Materials preset including the emitting surfaces would be the best choice, or a Shader Preset for each surface if you want to be able to use the settings on different items.
I've used Scene Subsets and it works fine for what I do. As Richard notes, it'll save the geometry for later reuse, and everything else about the emission settings.
To explain why a Light Preset won't work, mesh lights aren't lights to D|S. They're only lights to Iray.
It's the Ghost Lights by Kindred Arts. He said a Scene Subset should work so I tried that yesterday, and no matter what I do it says I must select a light in the scene. They are selected, and I made sure they had luminance assigned (so there were values) No luck. I tried them as Debugs (the light panels showing) and tried them Apply Before Presets (so they were hidden) and Apply Before Presets PLUS luminance. No luck, no luck, no luck- same error message that I have to select a light in the scene. Tried selecting one, tried selecting more than one, no luck.
That's the message you get when saving a Lights preset, not a Scene Subset. Are you sure you were selecting the latter from the File>Save as menu?
Yeah, it's a light preset, not scene subset. I was just getting ready to come back and correct what I said, my first post was correct (that I did this morning, except I was also trying Edit>Duplicate Nodes to hide the hierarchy, THAT won't work as a scene subset.) Can't save as a light preset. I'll just have to settle for the scene subset.
Remember how camera Headlights automatically turn off when you add a real light to the scene — except mesh and environment lights don't turn off the Headlight. This is the same thing, D|S doesn't see these as "real" lights.
Yeah, cute little fakers.
