Ah I see. I assumed you asked about existing VirEnce boards. AFAIK, I’ve never seen any flashlights made using this LED as OEM. The only flashlight I knew was Jensen567’s P60. Maybe he’ll be kind enough to share his builds to us here.
And as for the 119 boards, Djozz tested these LEDs with his 119 board. But the gap is too wide for it to work properly. You need 0,2mm gap with E21A/E17A. Nichia E17A/E21A series (April 19th: updated with output tests in the OP)
