Wow, thanks for the detailed responses.
Especially the tip about where to hold the head, I do not want to open that. Mine is smooth as butter, and as far as I'm concerned it's powered by magic and I don't wanna let that out.
Effective is good
Curious
Would these have worked?

Nobody boils in a bag to soften the glue?
When the going gets tough I make a set of these.
.
Haven’t found a light yet a set want open. It was the only thing that would open My V10R, Sunwayman used the dreaded red loctite. I tried everything including lots of heat while trying to break it loose. Spent a hour or two making some aluminum clamps and put one in the vise and the other with a big adjustable wrench tighten down. You would think with that much leverage it spin right off, nope took quite a bit of effort even then. I honestly thought I was gonna break it I turned so hard. Red loctite is no joke when they apply a little to much. I’m just glad no one else seems to use it.
I think Fenix uses red loctite.
Thought my needle nose pliers might break trying to unscrew the pill on an LD-02 there was so much loctite.
I found heat is the only thing that really helps. On my car brake cleaner helped once.
Maybe your biggest soldering iron set to max on the pill first.
Yes, it is more obvious from a picture taken with an angle and it confirm what I noticed from another picture. 
Funny thing, Honda (or their dealers?) sometimes used red loctite on the screws for their key fobs. Customers would have to take them to Honda to be drilled out, or risk breaking a key fob that cost $70-150 to replace. All over a tiny lithium coin cell that cost at most $4 retail.
I tried with one strap wrench and my hand, but the rrt-01 resisted. I'll grab one of my old belts (don't mind ruining it with pliers marks) and try again some time.

I used painters tape wrapped about 20 times with vise grips on each piece to remove all mine but one. So far the original RRT01’s haven’t been that bad, shouldn’t take but a few more pounds of torque than what you can turn just using a hand grip. I did have one that I taped up and turned off by hand without the vise grips. The tape gave me enough grip to twist it loose. I guess it all depends on how much glue they use on each light. The glue on these I have seen has been some kind of clear milky looking glue.
If you can get a little better grip it should break loose.
I recently opened a TCR1 and the bezel just wouldn’t budge. I had to use the V11R aluminum clamps (same size head) to get it break loose. The two piece head came apart just by hand but the bezel had been over glued, just my luck.
My second order of the KD reflectors I found to work, came in today. I replaced the factory one in a 219b sw45k emitter swapped TCR1 today, turned out great vs the factory one.
Since these KD reflectors have a very lite orange peel, I thought I might try the Old-Lumens splatter effect and see if that smooths the whole beam out even further.
Just to verify, we are talking about the 2019 RRT-01, right? If so, does the new reflector deminish the throw of the original? Is it a choice between having rings and throw or having none?
Can you please provide the link for the reflector?
Also, “Old-Lumens splatter effect? Newbie here!
I received the reflector today. Don’t remember which of the two I ordered.
Good news, no rings!
Lesser news, my bezel doesn’t screw down all the way anymore. I have a gap of 1mm. I already use the thinner lens.
Gonna keep it for now as the beam improved big time, but not so sure it is waterproof now.
I am using it with a 3000k sst-20 btw.
No they do not fit the 2019 version
@Geuzzz
Are you using a thin led protector like these. http://kaidomain.com/S024679-15_6mm-L-x-9_5mm-W-x-0_9mm-T-White-Plastic-Insulation-Gaskets-for-Cree-XP-L-5-pcs?search=led%20gasket
Mine all screwed down down past the o-ring. The mcpcb thickness would also make a difference. I replace the factory one (which is thicker) with a 16mm filed down to fit copper mcpcb. http://kaidomain.com/Flashlight-DIY-and-Tools/led-pcbs-or-mcpcbs/S025781-KDLIGHT-XP-16-DTP-Copper-MCPCB-for-Cree-XP-Series
Yes I used that lens. Probably just the thickness of the mcpcb as I am using the original. Guess I have to find some motivation to sand it thinner one day. Thanks for the help.
Nope older original model RRT01 and TCR1 alike.
Old-Lumens called it stipple. Video - How I Stipple a Reflector
I have used it several times with great results.
I put a 20mm “convoy” tir lens in my 2019 rrt-01. Very easy drop-in only a fat oring is needed under the bezel ring to compensate a smal height difference.
Did you use the glass lens or no?
Yes, with glass lens.
lovely
those pebble tir make for nice evenly lit photos
on left is a pebble tir in a Tool (thanks to contactcr), middle is Tool w stock reflector, right is a pebble tir from clemence
you can see in the middle photo, that a hotspot creates a poor image due to some parts being brighter than others, and this alters the colors
Original RRT-01 driver, reflector, and pocket clip supplies available.
I learned thanks to moderator007 that the driver in the 2019 RRT-01 also fits the Original RRT-01, and the TCR-1. He also found 2 reflectors that are drop in replacements for the Original RRT-01 and NiteEye10, to improve the beam.
