Q: 1. Does dimming this using an inline dimmer cause an audible hum? I'm trying to get new lights that don't do that. I know I can use scrims too, but I'd like the flexibility if possible. Thanks!

A: You're missing the point of these lamps. If you want to dim it, the best thing is the scrims. They are very effective. In addition, if you are opposed to using scrims for some reason, you have the option of pulling the bulb back. If you need more focus than when it is flooding, you can use barn doors, which you probably want any way. Finally, you can also use a 300W bulb instead of a 650W.

A: 3200 Kelvin, or basic Tungsten. You can add color temperature gels to change it, which is what I did.

Q: 7. can this light be triggered by another flash?

A: Yes, the nature of it is that it's triggered by a flash. I have three of them, so I connect directly to one through a cord, and that one triggers the other two. But I have also found that my bounce flash will trigger any of them as well, and I think that's what you're asking about.

Q: 8. Are these lights tungsten or daylight ( 5500K). Can I use my Nikon on auto white or have to balance?
