how does it cycle through the levels? is it half click per level or is it half click and hold while it cycles through all levels and release once its at the one you want?
would the lumen output be closer to the advertised output if you used a higher discharge battery such as the samsung 40t?
Using a Samsung 40T produced the same output levels. Per my SC700d review HERE, the 48G was able to drive the Zebralight SC700d to 3,000 lumens with no problem (so 2,000 lumens would not be an issue on the S21A).
Hi, I decided to check out a "S21" light as sold on ebay and it must be similar to the one being discussed. On the side it says "Manta Ray" and S21. Not a bad light for $22.28 shipped from China.
Battery Configurations: 1x21700 or 18650 3.7v, mine seems happy with a 18650.
Options: Luminus SST-20-W LED (6500K/5000K/4000K/3000K) - I ordered the 5000K which looks OK, has kind of blue/purple rings around the outside. Would have got the 4000K if I new what I know now. Emits a whine at the lower modes but I can only hear it close to my ear.
I also ordered a "Convoy S2 + Mit Luminus SST20 4000K Military Flashlight Hunting Tactical Torch" which looks similar and is cheaper after shipping, but it's not here yet.
-Dick Locke p.s. I'd post a picture but not able to, only a link? New to this forum so not sure what's up with that.
depend wich arrive later at 55°C
That mean it have better heat management
but yes they are very similar,apart pill S21A that I like much,hope to see this pill in copper for single and triple/quad.
