Autodesk Revit MEP

[#1]

I drop my lights on the grid and the attach find.  My problem is that the lighting is not populating on my schedule to tell me how many foot candles are in the space.  It shows the wattage.  The funny thing is, if I drop in a standard recessed 2x4, then it will, but for this recessed family, it won't.  I assume it has something to do with the family of light fixture I'm using.  I downloaded it from the Manufacturer's website.  See attached family and screen shots to hopefully help.  Any comments or suggestions would be much appreciated.

I placed several instances of this light fixture into a Space, hosted to a ceiling, my Space Schedule reported an Average Estimated Illumination of 0 fc regardless of the number of fixtures. However, upon opening the Family and changing the Photometric Web File (.ies file) to something else, the schedule began to report result higher than 0 fc. So check out that .ies file, perhaps that's the culprit.

What version of Revit are you using? My thought was that the ceiling geometry is blocking the light source. The Room Calculation Point feature would fix that, but that feature was added in 2013.

I tried that numerous times and still nothing.  I actuaclly have the same issue with a couple of other LED downlights from other compnays, one being Cooper.  I have sent an email to Daybrite for help.

If anyone knows of another manufacturer's LED recessed downlight and has good results with it, please let me know.  I need something to spec in my model to design with.

I'm running the latest, 2013, i will try that now.... wish me luck!

This didn't solve my problem.

The Room Calculation Point was the first thing I looked at, too. Anyway, check on Autodesk Seek to find a "stand-in" fixture for the meantime.

Are the LOAD CALCULATIONS checked in the electrical settings?

Yes

It could be the photometric IES files is using absolute lumen output? Most LED fixtures are only providing absolute lumen files and not the old relative photometry. It is probable the lamplumen value is not provided in the IES which might be how Revit calculates light levels.
