Hmm, I didn't think about the color balance. Since it worked with Super 8 indoors I thought it might have been the same balance as a strobe.
Thanx for pointing that out.

If I remember correctly, it was quite bright, so a filter shouldn't be an issue, and I'm not against Portra 400.
The last time the light & camera were used I was in my early teens, so I don't remember if my Father had different Super 8 films for indoor and out. I know he didn't have a filter, but never really learned anything about it.

As for "daylight" fluorescents, I know how those work and they are no substitute for daylight.
