I've been advised the heaters in these tubes produce IR; further, if used as
the primary white light source within a darkroom, one should wait until they
cool down before exposing IR even in "total darkness". I've never tested
this advice, but it seemed like a  simple enough precaution to employ. I've
never felt I wanted to invest the cost of IR film to test. Since I have not
had personal experience, take this with a grain of salt.
