One of my favorite mods - a blue FW3A that I swapped SST-20 Deep Red into.
This is with a fresh Molicel P26A 18650.
Thing rips.
But I mostly use it at low levels where it’s very efficient.
I love deep red because it does not attract insects and it’s gentle on your eyes at night.
Very nice pic. It had never occurred to me before that a powerful DR light was useful. I always had thought of DR as being for when you want minimal light. But now you've got me interested.
