Interesting. It has been a while since I heard from/about Mateminco. When @Lexel left (and thus stopped making their drivers), Mateminco kinda went off in a different direction too.
The lighted tailcap thing was developed by BLF members in the mid-2010s, like in this thread and a few others. If I recall correctly, the first commercial lights to use it were the BLF Kronos X6/X5, though that light had the simplest version of the tailcap. People made much fancier versions too, and I even made firmware for a RGB version once, but the practice fell out of style soon afterward when the community’s focus shifted from clicky-switch lights to e-switch lights.
About this particular light, SL02, it looks like it would be pretty comfortable to hold and to use, and the optic seems really interesting and pretty. The ~6 cd/lm beam seems practical indoors and short range outdoors. Includes long and short tubes. The lighted tail appears to be one of the better implementations I’ve seen, too… though my favorites are some which show battery status by how many LEDs are lit up in a ring around the button.
However, it also seems to have some pretty significant downsides…
- Really bad mode spacing – has only moon, high, and a little bit higher
- +14 mduv tint is too green even for cool white
- UI: Reversing one level requires rotating through all modes in a circle, but not too fast because that’ll activate strobe… and it has a disco mode in the main sequence. Has no option to turn off memory.
- Has front RGB but it’s only used for fast random disco mode, not for anything with a useful function
- Unregulated driver with direct-drive style output curve on all levels
- Built-in charger behaves badly enough I’d classify it as broken (ish)
- No physical or electronic lockout
- The manufacturer’s candela / throw specs are wildly inaccurate
Personally, I’d pass on this one. I mostly just use ~5 to ~50 lumens, and the SL02 has no output modes in that range.
BTW, a minor formatting thing I noticed… the Manufacturer Specs table lists Emisar in the header.
