I really like the one I’ve got. A very nice quality mid price-level 1x 18650 with the unique touch screen functionality.
I’ve put mine through 4 or 5 battery swaps and all the output changes involved in that. I don’t see/feel any changes/issues with the touch functionality. Screen is still pristine thanks to the included screen protector.
It’s not like one of the iphone/smart phone screens. It’s more like a calculator screen as far as it’s rigidity is concerned. It takes some pressure to change output instead of the slightest touch like a smartphone.
If you’d like to see some other comparison shots list out some lights I have a few of the more common budget lights in my collection and I’ll be shooting some more beams for another review tonight or tomorrow anyway.
But the entire review was FANTASTIC. Extremely informative and well written.
Now that I’ve seen the beamshots, I’m feeling mixed about the pronounced corona. It may just be the pictures, but I don’t see much blend (or, conversely, do see distinct transitions) from hotspot/corona/spill.
It’s just in the pictures. The distinctions are far less in person. It’s probably the part I struggle with the most in capturing.
I’ll try to describe it.
At a distance of 10 yards the DD2R’s beam is fairly smooth. There is a definite hotspot though less defined/concentrated than that of a C8 or L4 which have wider and deeper reflectors. The corona is fairly blended with the spill and not really discernable unless you are looking for it.
Out around 50 yards there is a hotspot and some usable spill. The corona is very well blended into the spill. More usable spill than an L4 or C8, the trade off is a less intense hotspot in the DD2R.
Out around 100 there is a hotspot and the spill isn’t very usable.
Pushing the usable hotspot out somewhere around 175-200 yards is pretty much max.
