The ring function is similiar, but the V20C spends a little longer at the lowest levels before noticeably increasing output. Checked out the Stevens'selfbuilt Today, 07:37 AM

At what distance did you measure the lux?
If too close, the beam has not formed yet, and you'll get a false low for example.
