Hi There,
I am having the most bizarre problem. For some reason, the artificial lights I have inserted into my revit 2014 model do not register when I go to render. If i am in plan view, I can select the light fitting, and it comes up with the option to add it to a group etc (so it registers that it is a light fitting). However, when I go to a camera view and open the rendering dialog box, I set the lighting setting to interior sun and artificial and try to click on the 'Artificial Lights' tab to turn them on, nothing happens. Nada. Nix. The lighting dialog box should pop up so I can select the lights to be switched on but nothing happens.
I used the exact same light fitting in a different project and it worked just fine.
Does anyone have any suggestions on how I might fix this?

This is probably either a light fixture problem - a lens around the light source is a solid instead of transparent material or the light is above the ceiling and does not cut a hole in the ceiling. << I bet it is a material issue.

I have checked the materials and the lens is transparent, and the light fitting is cutting correctly (and as I said I have used that exact family before and it worked perfectly). I even tried with a completely different fitting and had the same result.

Using the same fitting before doesn't matter if it was a different version of Revit or even just a different project so heed the warning....
I re-read your question ....The Artifical Lights is not greyed out or is it black with a blue border?

The Artificial Lights button in the rendering dialog box is the normal grey colour, not ghosted or black. When I click it, it goes blue and then pulses blue, but no lighting dialog box comes up.

Lets determine if it is your program or your project. Open the sample project that comes with 2014 and goto the 3D View and render dialog... what happens these? Does the light settings work? If so, then something is wrong with your file or lights. If not, then your Revit may be corrupted.

In the sample project, the Artificial Lights button works as it should, so Revit is not corrupted. What could be the problem with the project that this is happening?

Create a new project and place one of these lights - what happens....?
BTW - Are you using design options?

In the new project, all lights work normally. I am not using design options.

Well I managed to sort the issue in a very round about way. I just started a new project and linked the original project to that. Then the lights registered and rendered normally (thank goodness!). I'm still not quite sure what might have caused the original problem, but at least there was a work-around.

I'm having this same problem - (I've tried everything!) how did you link a new file to your old one?

It sounds like you need to make a lighting link to turn them on I had the same issue a while back and learned to link them together. Click the render button in the ribbon then in that window click artificial lights after you have one of the artificial light selections picked sun and artificial etc.. By default all of your lights that it recognizes show up in an ungrouped folder, click new name it lighting link, then one at a time move all of your lights to the new lighting link folder using move to group. once they are all in the grouped folder lighting link click ok and try it out I hope this helps.

@TLH09C, I simply created a new project (eg project-Y), opened the "Insert" tab, selected "Link Revit" and linked in the project (eg project-X) with the faulty lights. You can't edit project-X in project-Y, but any chnages you make to project-X will be updated in project-Y.
