I realise this is probably a bit too late to be useful, but I was trying to work with the LP .ies files and noticed that the ones in the BIM download catalog (.bim.ies) are slightly different than the ones mentioned here. For one thing, the testlab is Intertek, not LumenPulse. And also, the headers are properly formatted, no -1 in play, just the normal intensity value.
Anyway if it still matters to the few trying to incorporate LumenPulse into your work, give a look at the Tecnical Files - Revit (BIM) section
