Just registered at this beautiful place, though I've been peeping around for a while now.
Anyways, for an upcoming dance concert, I would like to use blacklight. I was wondering that if I had six 4' 40 watt blacklights, would that be enough to cover a stage with a width of 40' and a depth of 30'? Not sure how exactly I'm going to end up placing them, but probably spread four of them downstage and hang the other two from a batten. Would this provide an adequate wash? And if so, what about if I include the apron for a combined depth of about 50'? The apron won't actually need to be lit but it will save my backstage techies from placing and taking off the lights before and after the one dance. Or maybe I should place all the lights on my battens? (I'm sure working out how to cramp 24' feet of blacklight into my already cramped battens will be just joyous. )This would be a drop of about 25' from the stage to the batten.
And then I've heard that there are some gels that provide a decent substitute for actual blacklights? What are these gels (besides the wood's glass filter) and how well do they work in lieu of blacklight? I'm trying to do this without renting anything but if that's what it comes down to, so be it.
Sorry if this topic is supposed to go in the fx forum...?
