I just got a Flashpoint monolight, and it fires the flash whenever I lower the power setting, presumably to discharge the capacitor. I'm wondering if this is normal for a monolight since I don't remember this happening when I used Genesis lights before.

yes, that is normal. And it also does the same thing with the genesis. I'm not sure about the 200 but I had the 400 before and it does the same thing.

Yes, this happens on Genesis lights, too. It's auto-dumping the capacitors.

Seconded, my Genesis 200's do dump when the power comes down

They have to dump one way or another. However, the better flash units do it passively, without actually flashing.

But nothing comes free. The lower-priced units that dump the power without flashing are rather slow at it, taking maybe three or four seconds (you might as well flash the unit yourself to get it over with quickly); for much more money, you can get one that passively dumps very quickly.

The Genesis 200 dumps almost immediately when I lift off the power button - I've not noticed it take a longer time. Or do you mean even cheaper units? :)

Does it flash-dump or does it dump passively ("silently")? The posts above seem to suggest that it flash-dumps. Flash dumping does occur immediately; it's the "silent" dumping that can take a few seconds in lower-cost units.

It flash dumps - thanks for clarifying, I was wondering if I was missing something :)
