Hey brummygit, ordered a Desert Tan S2+ myself recently (directly from Convoy store @ AliExpress), and arrived today. Mine has a 1.4A driver and 4C LED tint (neutral white). The Biscotti firmware includes some modes with 50% as highest, so you could set those if unsure about running the LED @ 2.8A. Yes the light is bound to heat up quickly at that current.
Pocket clip was shown in photos, and fortunately came with the light. Pro tip: unscrew the switch part, slide on pocket clip, re-screw switch part. That way you'll leave fewer scratches than pushing it in place directly.
With smooth reflector it's too throwy for my taste, so I ordered an orange peel reflector (sadly only 2x) to go with it. Installed that, and the beam becomes much more floody (read: useful in day-to-day use). Imho the S2+ would be a better light if orange peel reflector came installed by default rather than smooth reflector.
This light isn't a thrower, period. Aim for the EDC / bicycle light double duty where floody makes more sense.
LED tint I ordered was 4C. It's too bad there isn't anything between that and warm white (7A). With smooth reflector the corona had a slight yellowish area in it. But nothing too bad, and overall fairly close to a NW ZebraLight I have. And none of the greenish tint a Titanium Olight S15 I have comes with. Orange peel reflector made that slight complaint go away...
Still doubting between neutral white & some warm white LEDs I ordered with it...
As for the color: the diamond shape knurling in Desert Tan color is very stylish & well done. Much like on the ZebraLight I mentioned before. Price/performance ratio really is top notch for the S2+.
