Hi All

I don't know if I'm missing something here but I can't seem to figure this out. These are the things I've read.

1. When taking flat frames, the general consensus for exposure time is around 1 second (correct me if I'm wrong).
2. Camera settings and optics should be the same as light frames.
3. I should aim for around 1/3 along the histogram.

The light panels advertise super bright LED light output.

When I try taking a 1 second exposure with a light panel with ANY light output, my image is pure white and massively overexposed.
Why are light panels so bright? What settings are used to get to 1/3 histogram. I can't seem to achieve this, without dropping my exposure to a tiny fraction of 1 second.

Any help on this one please?
