Luminaire Equations with IES File in Revit/Elumtools

[Anonymous]

I'm working on an existing project where some of the lighting that was placed were generically modeled to be "x" length. I'm updating the generic models with IES files currently to give more accurate results for photometrics and ran into a situation.

Currently some of the lengths generically modeled are non-typical lengths (ex. 37' for continuous rows). Is there anyway in Revit to create a formula that has the lumen output associated with length or will I have to manually change it for each individual instance?

I tried using Fixture_Length * 500 (expected output per foot) in the luminare output field would work, however I'm unable to have equations refer to other parameters (according to error message)

According to Second part of that message it can't be done period.  But the first part of the Message is saying you have no "Length" Parameter to multiply 500 by.   

...another thing to be cognizant of is Parameter Type.  In this case,  "Luminaire Lumens" would need to be a Length Parameter for that Formula to work.
