I know there's been a ton of threads about this and I read probably all of them and still don't get it right.

I'm using Revit 2013 - and the recessed can lights that come with revit. When rendered they always stay dark.

1. I changed the wattage like Typhoon said by 100...but it didn't do the job.

2. Self-Illumination is clicked on - also doesn't do it

3. I even painted the inside of the can - nope

4. There is no glass inside the recessed can...

WWhat am I doning wrong???I'm at my witts end...I'm sure it's something minor...any help as always highly appreciated.

Hi Tectacoma,

Have you put "Light Source" into your light fixtures?

See this thread

CDWDavid...I checked the thread but unfortunately I don't know Sketchup

WWHub...I was under the impression the light is cutting the ceiling since I can see the fixture.

I copied the "original" revit fixture and placed an extrusion inside and called it light source...still not getting it.

You have a solid between your light source and the room.  Either it is the ceiling (no hole) or it is something solid in your family.   You will have to look again.

WWHub....so I checked again but I don't see a solid either between the fixture

and the ceiling or a solid inside the fixture ( I deleted the one I created earlier).

I moved the light source down earlier in the family as well but still doesn't light up. All I want is for the fixture (which is light can that

comes within revit family) to light up like the example I posted below that was done by someone else obviously.

Thanks for the all feedback.

Like I said before...it's probably something small...lol

I found the solution....

1. created my own custom light source in the materials library (probably not necessary but just copied in case...)

2. "Check" self-illumination box...

3. "Check" the REFLECTIVITY box...that's the one that was  un-checked the entire time..now it seems to be working.

thanks for all your feedback guys
