Richard,
halogen light of the kind of dia projectors (150W and 250W small
bulbs) is 3400K° and needs an 85 filter,
while halogen light of the kind it is generally used for photographic
purposes is 3200K° and needs an 85B filter.
I have been using halogen 1000W and 650W lights many times for repro
and countinuous light work and always assuming (more than that,
metering) their color temperature being 3200 and using T film with the
expected results.
(wratten filter values)
(sorry I lost the original thread message: I hope this was the
question)
