Hi.
I am trying to decide on a 50 deg Colorsource spot, and a 70 deg to replace our Force 4 instruments. our Procoeniun is 30' wide, and our FOH bars are 6', and 12'. We have a throw of about 15'. We only have 10 F4 50 deg and 5 old strand pattern profile spots to fill in the dark spots.
I have looked at the photometrics for the 50 deg and 70 deg spots
https://www.etcconnect.com/WorkArea/DownloadAsset.aspx?id=10737484687
and see the 50% lux for the 50 deg has a wider spread than the 70 deg. I gues this means I would have to overlap the fields more. I presume that if I use a frost gel, this would help.
I have no idea how much illuminance is needed for a production. The 50 deg has 64 fc, the 70 deg 40 fc. How do these translate to acceptable onstage lighting?
I am wondering if I go with the 50 deg, I may need 4 light pools downstage, 8 instruments, but If I go with the 70 deg, I could get away with three, and 6 instruments.
Any suggestions?
Thanks,
John
