Not sure if I am right, but I did not see a option for OP there??
Please correct me if I am wrong. Looking to buy, Thanks

From the PTS-Flashlights web page for the T20C2 MkII

Special Note: This item comes with a smooth reflector (MAX throw) but we would be happy to change it to an OP/textured reflector (Smooth Beam) for you, just make a note in the comments box during your purchase.
I just ordered one tonight and included a note comment box at checkout so we'll see how it goes.

Thanks for support everyone! :grouphug:


Yes, it is very unusual - I have never seen another example where that has occurred. But in this case, it's due to the dark void in the center of my smooth reflector module - because the OP one doesn't have it, the center of the OP version is technically a bit brighter. Note that the the periphery of the hotspot is brighter than the center on the smooth reflector version, but I take all my measurements from the dead-center.

I'm a little confused about the available reflectors. I read somewhere that this model comes standard with an "LOP" (Light Orange Peel) reflector, with an OP and smooth (SMO) optional. The LOP doesn't seem to be mentioned in this thread. How many different reflectors are available and if there is an LOP reflector, what are its characteristics relative to the smooth and orange peel versions?

Thanks

there you are - mcpingist...
:welcome:

here is a cut n paste from an email I just sent a customer with similar questions relating to T20C2 MKII:
"when I measured LUX output (center spot intensity) between the three reflector types w/ XP-G R5 LED I found on average:
LOP offered highest LUX
SMO was about 6% less
OP was about 12% less

LOP had furthest throw, OP had less throw (which makes sense)

SMO having less throw than LOP is what was a surprise to everyone initially, as this is counter intuitive, and not the case with R2, Q5 and previous LED models (SMO typically offers 15-20% MORE throw)
But SMO w/ R5 LED typically produces a darker center - almost a donut hole which is what is being seen/measured by the LUX meter."

perhaps I am sorting my reflectors differently than others - :shrug:
when pre-testing, I run across some modules that have more texture, and thus a smoother beam transition than the LOP and set those aside and mark them as OP.


FYI, ET announced this week that the T100C2 MKII's are no longer going to be offered in SMO or OP choices - and their default for T100C2 MKII model is now LOP...
so I think we will see a continuing trend as they migrate away from multiple reflector choices to a single factory recommended/default choice. (it would certainly make my life easier!) :)

as always... YMMV

Thanks Tod. I believe you were the original source of my info. I was curious why I hadn't noticed others even mentioning the LOP and was interested to see if anyone would confirm or dispute that info. No disrespect, just a newbie trying to make sure I understand things.

Thanks

Very interesting about the LUX on the LOP reflector.

thanks for posting! :thumbsup:

From the runtime plots it doesn't look like it hits the cell protection cutoff on an 18650 (you can see all the lights clearly do on 2x RCR). This means to me that it won't suck an unprotected 18650 down into the ground. Good news for the laptop battery extractors among us.

I just noticed that I can change the settings by pushing in on the bezel instead of twisting. Will this damage the light?

Don't worry. The changing is always done by pushing, but normally that pushing is done by the threads. At some positions the play in the threads allows you to do that by yourself.

UPDATE:

I’ve just updated the main thread with the results from a new XR-E R2 drop-in for the T20C2-II. Eagletac developed this module to restore the throw characteristics of the original T20C2 (which many seem to like), while maintaining the build and user interface updates of the Mark-II design.

The new XR-E R2 drop-in for the T20C2-II:

Ealgetac003.jpg


Since the Mk II head dimensions have changed slightly from the original T20C2, this drop-in has a slightly narrower width than the original T20C2. Orange Peel texturing also seems a bit higher on my sample. Still, I suspect this new drop-in will go a long way in restoring the throw and output of the original T20C2 - but with the new T20C2-II interface.

Here are some up-close white-wall beamshots comparing the new T20C2-II R2-drop-in with the original T20C2 (XR-E R2):

T20C2-R2003.jpg

T20C2-R2002.jpg

T20C2-R2001.jpg


Basically, throw seems pretty comparable, but the new drop-in is also more ringy beyond the hotspot’s corona.

I can't do side-by-side shots of the XP-G R5 and XR-E R2 modules for the T20C2-II (I only have one body ;)).

Here are some external 100-yard beamshots (sorry, I forgot to test the XP-G R5 version :ohgeez:). Please see my Outdoor 100-Yard Round-up Review for more info on these shots.

Again, there is not a huge difference, but it does confirm what you can see in the white-wall shots – the new T20C2-II R2 drop-in throws similar to the original T20C2, although with some relative variation in the fore- to mid-ground rings.

Here are how the T20C2-II with the new XR-E R2 drop-in compares to other lights of this class (note: this configuration is identified as "T20C2II (XR-E R2) OP" in the table below).

Eagletac-Summary3.gif


Again, these numbers confirm that the new XR-E R2 drop-in for the T20C2-II performs close to the original T20C2, but with just a touch less output and throw on my sample.

Please see the main review thread for all the runtime results. Here's a sample:

T20C2II-Hi18650.gif


Basically, the new XR-E R2 drop-in has comparable output and runtime to the original T20C2 XR-E R2. Any variation you are seeing there is likely just due to the binning (i.e. all R2 bins have a ~7% variation of outputs).

Bottom line, this new XR-E R2 drop-in for T20C2-II effectively restores the output and throw characteristics of the original T20C2, but with the build and user interface improvements of the T20C2-II. A good option for those who want it! :thumbsup:
