Thanks Neutral Fan!
Yes, OP or even an optic would be nice for this light, better than the SMO reflector, because it causes some rings and even a small “artifact” in the hotspot due to the centering.

The 2xAAA is new to me, but I don+’t dislike it! However, the 2xAA feels more comfortable as the Tool 25!

About the LEDs, I remember someone was selling something like that around here, but can’t remember who, nor even if it was this specific type of LED.
It produces a great beam and in tint in my opinion :slight_smile:
