Using OS 2.2.0 and it will not let me set the parameters for a Luminaire Definition. Whenver I enter wattage it resets back to zero and the fields for "fraction radiant" etc. are grayed out.

Luminaire Definition

Updating this to answer my own question because I realized that clearly I can enter the same information in the Lights Definitions. But that raises the question of what's the point of the Luminaire Definition?

@craigers Thanks, you found a new issue. I did see that it does let you enter a value, but only between 0 and 1, which isn't very useful, it should be updated to accept any positive value. I filed an issue for this

As to what Luminaire objects are for, it is very much like using a Lights object with a "Lighting Power" value. In EnergyPlus Luminaire's end up as lights. Luminaire's can be added in the SketchUp plugin at a specific position and orientation, the long term intent, which there is no current planning for, was to enable electric lighting analysis in addition to daylighting analysis.
