We use a set purchased from Fotodyne which consists of a Wratten #2B
on the gel side and a Wratten #22 (orange) on the camera side.  The filters
can be purchased separately; I think the price is about the same either
way.  If you're in a hurry, a larger photo store will have them.

[I have no connection with the above company.]

I hope this helps; e-mail me if you need more info.
