Missing Photometric?

Deke

Typically I can add a Distant Light and then turn on Photometrics in the Lights Editor panel and adjust lumens and temperature. For some reason in the project I just opened there is no photometric option. I know many menus in Daz are contectual. What's the secret to find that photometric ON button?

Oh...just answered my own question.  The Photometric button in the light's panel won't show up unless the Renderer is set to Iray.  Sometimes I really hate contextualism.
