6-8 deg hotspot with spill

If you have found 26.5mm carclo, you could check 20mm version as well.

20mm first, 26.5mm second
But note that there will be almost no spill, most light goes to this angles (7-10 degrees).
If you need smaller hotspot with less amount of light in it and much more light around, you need reflector.
