Light question on Studio Type Room - ceiling lights

Is there any easy way to get the can lights on the ceiling in the various rooms to work as Iray lights? I'm not finding anything obious, but the wire-frame view indicates they could be rigged for lighting.

    select the surface of the bulb, apply the Iray uber base shader, and change illumination color from black to white (now it's on). Defaults make it so dim that you won't see any light though, you have to crank up the luminosity to like 50,000 or something to start seeing it.  Adjusting the color temperature will change the color, 6500 is pure white, 5300-5500 I find to be a warmer yellowish but your mileage may vary.  You can always set it to 6500 and just change the illumination from white to whatever color you want if you want colored light, that works too. Give it a shot!

    That's the problem - I can't find the bulb(s) anywhere in the surfaces list; I'm not even sure I'm finding the can lights themselves.

    I would probably use point lights,  with IES profiles attached...and just pick the color temperature of some common bulbs. 

    Render 1 is a simple can light with the bulb set as an emmiter..to 75% convergence...15 minutes.

    Render 2 is a point, set to disk.  to 80% convergence...55 seconds.

    The actual times don't really matter...it's the difference that does. 

    If the bulb were a single plane or just a couple of faces, the difference would be much less, but the more complicated the geometery the longer the render time.

    Yeah - that's the way I'll be going; I was just hoping I'd missed something in the set. It does light reasonably well with just a sun/sky exterior and the rim lightng in the ceiling. Buut there are all those black can lights just hanging there, with no light - doesn't look right. Really nice set, otherwise.

    Are you sure there isn't a setting for them as they all seem to be lit in the promo images?

    I can't find it, if there is. I spent three hours looking for it last night.

    As much as I like it, I think it's going back. Among other things, all the walls are part of the floor and can only be hidden by playing in the surface tab - and the outside wall doesn't offer that as an option. I can't find anything on the can lights - if you look at the promo image for the bedroom, there are light scallops on the wall, as though the can lights were doing someting - but the lights themselves are not showing as emitters in the picture.
