Test conditions
-- Date/time: Jan 1 2022 2:20pm PST, northern Calif.
-- Both display panels connected to the same 12v 35Ah AGM battery.
-- Voltage during the test held steady at 12.4v.
-- Both panels were slightly tilted down (by ~2 degrees) to point any red acrylic filter reflections down and away from the viewing direction.
-- Sun was behind and to the right of the panels.
Top display panel:

My local practice field
A short 360 of my local practice field in Lincoln CA. No green grass in summer but it has great thermal conditions for F5J practice.
