Has anyone used colored gel filters on exterior lights for Light It Up Blue? I have the opportunity to light up the Court House in my town and I could use some advice. I'm supposed to talk to the maintenance guy tomorrow and get more specs on the type of bulb (I believe it's halogen, which poses a problem with extreme heat), the size of the light fixtures, how we can attach the filters, etc. But if anyone has this experience, I'll sure listen!
