What emitter?

If anything it'd probably be a CSM-360, but I'm not sure even that goes that hard...
 
Looks like Citizen CLL040. When you look at trasparent 3D drawing you see a square shape of board with mounting hole in corner and big flat die. I wonder how they are focusing such a big LED (board is 28mm square) :thinking:

looks like they are using an aspheric and some sort of reflector between the aspheric and the lens.
 
With that big an emitter, you'll never get a tight beam. Probably floody with a big HOTspot.

Oh, and that's not one die. It's a board with many dice on it.

Abstrahlwinkel +/- 9° = 18°

oder +/-39° fokusabhängig =78°

like Cu insert and piezo switch too but weak point is IMO head connector ......whole thing get to to much light . (Ok for video but just for simple dive ? )

Bridgelux RS arrays will do upto 9000 source lumens on a cool white chip, looking similar to the linked citizen LED.
 
Bridgelux RS will do that as well but is much bigger. It is 50.8x45.6mm rectangle and is thicker at 3.8mm. CLL040 can also go higher, up to about 140W (324 individual LEDs version) emitting almost 13,000lm (5000K, 65CRI) and still having size 28x28mm. Efficiency of Citizen is also better.
