I notice you're asking for two different things: a download for IES lights in SketchUp, and an interesting paper idea. Let me help with both.
If you're writing a paper combining IES lighting simulation and SketchUp, here's a compelling idea: Why it's interesting: Most lighting simulation focuses on illuminance (lux) or energy use. This paper would explore how to model non-visual effects of light (melanopic EDI, circadian stimulus) using accessible IES data in SketchUp – bridging architectural modeling with emerging health standards (WELL, LEH). You could compare predicted circadian efficacy against on-site measurements, or propose a plug-in workflow for designers.
