converting .ies files

[Anonymous]

I work for  a lighting manufacturer and every fixture has a .ies file with the photometrics information. We have some customers that are requesting them in Revit format. Are ies files able to be opened in Revit or is there a specific file format for revit? How would I convert into that form? Thank you!

are those LED fixtures? 

Older Revit versions couldn't handle the absolute lumen ies files used for LED. I heard this was resolved for newer Revit versions. (I use elumtools plugin for lighting). My workaround was to manipulate the ies file to use the lumen number instead of the "-1" (or whatever the LED ies files use). I'm not sure if this method still is accurate, but it works. 

Other than that, ies files are the same. Revit on its own isn't a really good lighting design software. It doesn't do point-by-point and and assumes all fixtures to be at the height of the lowest fixture in a space.

Hi,

Revit does handle IES, it uses them inside Lighting Fixture families...

If you have a large number of IES files, you could look into an automated solution... Perhaps using Dynamo or an addin?

Hope that's useful...

Thank you for your reply. Yes they are LED fixtures. I am just trying to provide as much information as possible to my distributors so they can provide for their customers. So you are saying providing the ies file alone should be good enough to use for the current version of revit? Is there anything I can do on my end to provide a file that "Revit ready" for older versions? Just trying to make everything as seamless as possible.

Hey,

So yes, if you provide an IES, they can build a Revit family to use them... 

You could also provide a Revit family with the IES loaded in, they would find that more useful, but would be more work for you.  

If you use a Dynamo graph, you could batch create the Revit families... A little more specialist knowledge is required, but you could advertise your whole library being Revit... 

I guess your decision is a company strategy one 🙂

I don't know how older files might work i'm afraid.

Kind regards,

Mark

You can look through here. There are a number of different services there and you might find someone who can make the families for you.
