I have a photoshoot coming up this weekend, a last minute shoot filling in for someone who decided to cancel at the last minute.

Normally thats not an issue, but turns out I will be shooting a sports game that is held indoors in a small local arena. I'm going to have to set up some strobes on the rafters to get a good shutter speed, but I'm not sure what color temp mercury vapors run at. Anybody know? The only gels I have for my lights are the Plus Greens, are these close enough? If not what would I need.
