Daylight film and tungsten photofloods

I've been considering shooting some 4x5 E-6 but am concerned about colour balance issues with such an expensive material. I shoot mainly under 250W or 500W daylight balanced tungsten photofloods, the ones with the blue coloured glass (or interior coating). Although they are called 'daylight' bulbs, are they the same colour temperature that daylight films are calibrated to? Since I don't have a tri-colour light meter I'd hate to spend $3+ per sheet only to have them come out orange!

If they are daylight balanced Photofloods then you shouldn't have a problem. It's was once more usual to use normal photofloods with the Blue daylight balance filter on the lens but effectively you get the same results.
