LEDs 1

Bryce 7.1 Pro.

Render Premium 64 rpp, TA, Blurry Transmissions, Blurry Reflections, Soft Shadows, Boost Light, TA Scattering Correction, Maximum Ray Depth 6. Time is 2:25:08.
Lighting: Bryce Sky HDRI, Radial Light as a repeater HDRI.
Of course, when rendering a 256 rpp noise will be much less, but my computer does not want a long render.
All done in Bryce.
