Here are the outcomes for all of the S21E TIRs!
My personal recommendations are 15deg bead for throw, 30deg bead for throw/flood balance, and whatever wide angle bead for flood. I find that the 10deg flat has focus issues, and doesn’t throw visibly more than the 15deg bead. The 30deg bead has incredibly good angular tint uniformity, makes the beam rosier than most TIRs, and doesn’t make a hexagon beam due to the irregular bead pattern.
