I did say at the start the reflector seems a bit short at 50mm (it’s actually 48mm) in depth that may be an issue with the throw numbers being so low?

It’s probably a combination of that, plus being heavy OP, plus low output, plus not being focused just right. Even with all that, 550 meters sounds low.

If Sofirn wanted to make the reflector deeper, I think they can extend the light maybe 10mm-12mm here, then reshape the reflector.

This should not be too difficult and it doesn’t change the look of the light very much. I don’t know if they want to go through the trouble of that, though.

I think the reflector needs another 12mm of depth to equal the proportions of the L6/S70 reflector.

Has anybody checked with that calculator?
