I have never used the modeling light on my packs, so I don't know if this is normal.
On both my packs, the modeling light flickers about once per second.
Is this normal.
I wanted to use the modeling light to light some jewelry close-ups in a video I'm shooting. But with that flicker that won't work.
another thing: on one of the packs the light goes out after a while.
one the other it stays on. If you press the modeling light button, the modeling light goes out, but as soon as you release the button, it's on again.
I have to power down the pack in order to turn off the modeling light on that one.
