Kaidomain item S023423, 26.2 x 16.1mm. Remove stock gasket and replace with generic 5050. Re-used the original o-ring with a bit of silicone grease as it’s a tight squeeze around the reflector, but the bezel does a good job of forcing it evenly into the gap.
I tried the closest-sized OP reflector too, but it was too big.
SFT40 4000K? Just as glorious as you expect. I love the P16 but man does it get hot quick, even after swapping to an M35A instead of a P30B as there is some word it may be FET turbo.
