Pictures in both these posts were lit with AOAM RGB Critters (two of em) and Luxli Viola 2 LED panels (again, two of em). I’ve been using both since last March, and yes, the color on the RGB Criiter is gorgeous. I much prefer the UI, controllable color and adjustability of the Luxli panels, but sometimes I want to aim a flashlight at something, not light it up with a panel’s broad beam. I’ll be trying a Luxli Fiddle with its grid spot in Death Valley / Rhyolite NV in a couple weeks. That should help.

And I enjoyed your book Abandoned Planes, Trains and Automobiles. I lived in California (Bay Area) for 35 years.
