Having a green practical fluorescent without CC in post?

For a shot in a movie I'm working (scene set in a basement) I'm putting a tungsten fresnel shining down the stairs, CTB light through the windows, and there's a shop light hanging in the middle of the scene above a time machine. I'd like to get a decent green tint to it (more so than the natural tint) and I'm curious if anyone has any suggestions for how to do this?

My first opinion was to CC later, but since I'm mixing CT in several moving shots this would just get too complicated. The other thought was wrapping green gels around the 2 tubes, but that seemed like it would heat up too much.

Any advice?
 
get green bulbs from a store :)

or perhaps, if the light is in the shot, wrap green gel around it, and put it inside a china lantern.
 
Yeah. Night scene in a basement with just a 250W CTB light through a small window near the ceiling.

Covering the entire light with a gel may work actually. Is there a way to buy 4ft. pieces of gel online? All I'm aware of is filmtools.com 24" max sheets and then their 25' rolls.

Now you're confusing me. Above you said "fresnel shining down stairs, CTB over windows, shoplight in center".
 
Sorry, I was referring to what light was coming in through the windows since you asked about time of day.

Fresnel coming down the stairs, shoplight in the center, and a 250W CTB light out the small window.
 
Ah, actually didn't notice you were the same person that PM'ed until just now. Thanks for all the help.

There are two main locations for the film. A warm lit living room and a green and blue lit basement. The tungsten light on the stairs isn't necessarily motivated, but it's a visual reminder of what's upstairs.
I plan to WB under the tungsten Fresnel, but to a slightly blue card so I'm a little bit inbetween color balances and nothing is pure white.

Didn't think about testing flickering, a good point to check beforehand.
 
Here are a couple of shots from a short I did about a year ago. Both shots were WB for Tungsten with the blue gelled 650 (I think) shining through the window.

The one is lit with a china ball + practical, the other, just the practical.

Yeah, that's an idea.

Minus green the tungstens and white balance to that. The practical fluo will go green.

I did that on the fly, we were shooting a figure closeup with a long white hallway in the background. We decided we wanted a sickly green look for the hall. Instead of gelling the 20+ fluo ceiling fixtures, we just clipped a full minus green to the kino acting as a key light for the closeup. In telecine we corrected for the foreground light and the hallway went green.

this looks like full CTB. Am i correct?
 
The practical is tungsten. We might have used a 3200 balanced light, but I can't remember. The china ball is 3200K.
 
But the camera was probably on auto-wb and it just didn't know what to make of the scene with all the different color temps... :)
 
Keep it simple, use a daylight to floresent green gel over your practical flo light. Roscor makes them, they are called "window green".
