I can't find anything in the book about light sources creating dim light beyond their Bright light range. I'm going to default to what feels like a sane choice of Dim light extends twice as far as Bright.
So the Light spell casts 20' Bright light, and 20 feet beyond that of Dim light.

No. The light levels Bright and Dim Light and Darkness still exist, but light sources work differently now. They tell you exactly what range and how they illuminate.
Examples:
p. 184 wrote:
CANDLE
A lit candle sheds dim light in a 5-foot radius
So no bright light at all from a candle.
p. 187 wrote:
TORCH
A torch sheds bright light in a 20-foot radius. It can be
used as an improvised weapon that deals 1d4 bludgeoning
damage plus 1 fire damage.
No dim light from a torch. Just 20 feet of bright light and then a sharp drop to darkness (or whatever the background illumination level is).
