With the help of BanL (Thanks BanL) I finally got a variety of reflectors. After trying several different reflectors from Fasttech that didn’t fit, I even cut one down on the lathe to fit but was worse than the stock reflector my KD shipment finally came in. I now have two reflectors here that drop right in to original RRT01 with no modifications.
The both produce a very nice beam compared to the original reflector. I have only tested them using a LH351D shaved dome led but I don’t expect them to be any different with a 3535 led. Nice hotspot with even spill and no visible rings.
Reflector #1 being slightly larger in diameter (19.4 mm in diameter).
.
Reflector #2 slightly smaller in diameter (19.3 mm in diameter).
.
They look identically to my eye but when measured KD list the right dimensions, one is .1 mm bigger than the other.
They are OP reflectors but are very fine ripples, barely noticeable.
To me with the shaved LH351D the smaller #2 reflector has a slightly better beam but ever so lightly. It could be it just looks better with the shaved LH351D.
There not that expensive so it might help to order both and see which one works best for you.
The best thing is they drop right in with no rings…
