Try running a fogging test using your current lights. You may want to use smaller bulbs in the lamps. I think Kodak still has the test in their on-line technical literature, otherwise I have it (if I can find it). 

They do:

If the OC lamp does fog I agree with those who suggest laying a sheet of Rubylith over (under?) the regular filter. What Kodak calls a dark red safelight is safe for any orthochromatic or color blind material but is less visually bright than amber for the same actual light level and many find them uncomfortable.
