Hi all,

I'm shooting a scene for a music video and we don't have the budget to rent HMI's. I want to simulate sunlight coming through a window. My plan of attack is to place 2 arri 2k's outside of the windows. Now my question is this, which approach would allow me the most light intensity? Should I gel the lights CTB (I know this will reduce the light by 2 stops) or gel the physical window CTO? If I gel the window CTO would the tungsten 2k's coming inside stay the same color temperature 3200k?

You don't need to Gel anything.
What you'd do is tent the window to kill the daylight; block it out, and then throw in your own lights.

Normally I'd do it with 8x12 black cards and C stands and sandbags ;)

Yes you are right, but isn't this kill your natural ambient daylight in the room? I believe you can project your 2K tungsten (maybe with fresnel lens opened) through the window without any gelling and blocking the daylight. And in that way simulate late afternoon, low sun. This might work when you have a shady day.
