In my post above I should have mentioned that it was the *same* print that I made twice before comparing.
Since then, I too have finished a Kodak-style test with this led light. I used only one, located as I mentioned about 5 feet above my working area in a fixture with a metal reflector, aimed up at the ceiling. I tested Adorama Brand VC paper, with up to 7 minutes before and after threshold exposure. It tested safe. I suppose to be 100% forthright, I should mention that I preflash paper through a green filter, and that's what I did for these tests. Next up will be Arista.edu VC paper, which my old safelight setup caused to fog.
