lumenbeing, congrats on your new Cool White, Negative R9, Low CRI Light w tail cap keyring connection. Thats a nice feature but I dont use a light on my keys, I like it separate. I dont use the magnet feature on my Olight S1 Mini High CRI
The Olight S1 Mini High CRI is the smallest, and lightest of the Olights. It also has a useful high mode, in addition to moon, low, medium, and Turbo, a total of 5 modes. It also has a low battery warning light in the switch, so no need to open the light to measure battery voltage. I recommend the S1 Mini High CRI (despite its green tint). You might be able to swap on the S1 tailcap to gain the keyring connection.
I dont mind the mode memory, it can be useful, and I can always start on moon directly and ramp up
my cool white, negative R9, low cri lights see the least use
my High CRI lights see the most use, particularly the ones modded to Warm and Neutral CCT
he seems to be using a UV light to trigger the S1A to turn on
I tried my UV light on my S1 Mini and S Mini and they do not do that
here is what I mean by negative R9 (the Red bar)

you can also see that the CW LED in Olight Batons makes red look brown and makes orange/yellow more lime green/yellow
for comparison of R9, here is the Olight S1 Mini High CRI that uses an XP-G3, compared to a Lumintop aaa Worm w N219b (similar to the LED in the Lumintop aaa Tool and Maratac aaa)
