Nice. And thanks for the pointer for the small copper light; I asked about it somewhat tongue in cheek - that poor Reylight pineapple copper with single Nichia 219b barely has enough output as is. And too pretty to cap it with a diffuser. Rolling up the end of the silicone diffuser is a neat trick though.
Yeah the Sofirn SP36 diffuser is super nice and turns the flashlight into a wonderful lantern. I compared it with my LT1 lantern here Sofirn LT1 Lantern vs Sofirn SP36 BLF 4000k w/ Diffuser - Comparison of brightness and CCT tone with pictures.
