Hi LUCAS, it's simple the LUMENS for WATT is 17 for 1 ( 1700 Lumens=100 Watts)- INCANDESCENT LAMPS if they are FLUORESCENTES it's 17 for 60 ( 6000 lumens= 100 Watts)
-----------------------------------
I Hope and I Wish to LEARN more, and more, and more.... REVIT |

Need to know REVIT issue. 2008? 2009? In 2008 & AccuRender, the lighting family has an invisible line that acts as the light source.

I do not know what family you are modifying so I do not know if you have what you need. For spot source lights, you will have two reference planes in plan and elevation. If you touch these, you will see that they are labeled as source axis. The junction of these planes is the location of your light source and obviously, you want that inside your lamp. For linear lights, you will see the same except you will have an invisible line that is the light source. Note that you must have either no lens or a lens that has some transparency in order for your light to work. The inside back of your lamp should also have a reflective surface. Now, if you have this mdeled correctly, set the lumens under type according to Typhoon's post.

I did read your post - did you read mine? That light does not exist in my standard REVIT although I do have a similar one without the 39076_ designation. If the one you have is similar, all of what I posted applies. Try to do a little using what I explained and you may learn something. You don't even tell us if you want this to light. If you don't, ignore all that I have written and model it to look like you want!

Is there a way to make the 2x4 ceiling fixtures in Revit actually look like they are lit up? I'm getting the light out of the fixture to illuminate the interior of the building, but the light itself is still dark. When I render it looks odd. Any help would be appreciated! Thanks much

From your HELP: (It is your best resource.)
Light bulbs
If you want the surface of a light bulb to display in a rendered image, create geometry for it in the lighting fixture family. Then apply a material to it whose render appearance is Glass Light Bulb On. This render appearance mimics the surface of a light bulb that is turned on. It is white, shiny, and emits the appropriate amount of light. See Creating a Lighting Fixture with One Light Source.
