Unfortunately, I did not find the time until today to have a closer look at my K9.3 flashlight. I only put it out of the box into my shelf when it arrived. I wish I had looked at it closer a bit earlier. On the other hand, what I complain about is most likely quite nitpicky and functionality is fully given. I admit this is not a $ 1000 Oveready BOSS light but for a $ 144.48 flashlight I would still have expected less imperfections.
What I like:
It works to my satisfaction, well almost. I chose XP-L HI 4000K V2 5D for CH1 and SST20-DR for CH2 as well as a red switch backlight. The light came on in CH2 (deep red) and Advanced UI with stepless ramping. It puts a very decent big spot of light onto the wall. Deep red is quite bright on full power.
What could be investigated a bit more:
When K9.3 is on lowest brightness (FLOOR) those 9 XP-L HI emitters start to flicker like crazy, looking like candle mode is activated. Turbo mode for CH2 in combination with SST20-DR seems more or less useless as another doubleclick will immediately bring brightness down to CEILING level again. I am talking about 0.5 or maybe 1 second for stepping down. Thermal stepdown is programmed to 55°C and the K9.3 was still at room temperature. Maybe Hank can have a deeper look into this as I hope this is normal behaviour and that my K9.3 works flawlessly.
Something that took me by surprise:
The head has a significant notch, probably abrasion from CNC machining. It could not be caused by myself as you can see it's black anodized. Again, nothing serious but still it diminishes the otherwise nice look and feel. The stainless steel bezel shows some scratches right out of the box and a rusty mark where it touches the head unit.
Someone must have written something on the head unit. I can just about recognize "S7R R" written on it with some permanent marker pen. Certainly, this is nothing to rant about as I could clean it off with a cotton swab and alcohol. But still it's a bit confusing to see this on the outside of a flashlight. The black dot in the left section of the switch button is somehow distracting from the great red glow of the backlight, like a fly on the wall. ;-) I hope my second K9.3 that is en route already will have less imperfections.
After playing with the K9.3 for a while I discovered a software glitch in Andúril 2.0 that is maybe important to mention. The Lockout mode will be left automatically if you set the AUX lights to Beacon/Blinking. Fortunately, in most situations this is not a serious bug but still it can lead to unpleasant situations wearing it in your pocket and feeling certain to have locked the light before. I highly recommend ToyKeeper and Hank to have a look at it unless my K9.3 is affected only. Maybe some of you can reconfirm this glitch.
I made a video to demonstrate the software glitch:
I made following observations with the faulty AUX Beacon mode:
1. Go to Lockout Mode (4C from OFF)
2. Select Beacon AUX (7C via off - low - high - beacon/blinking)
Red Beacon (random duration, < 1min) => blinking turns off, flashlight is unlocked!
Yellow Beacon (random duration, < 1min) => blinking turns off, flashlight is unlocked!
Cyan Beacon (random duration, < 1min) => blinking turns off, flashlight is unlocked!
Blue Beacon (random duration, < 1min) => blinking turns off, flashlight is unlocked!
Purple Beacon (random duration, < 1min) => blinking turns off, flashlight is unlocked!
White Beacon (random duration, < 1min) => blinking turns off, flashlight is unlocked!
Colorful „Disco“ Beacon => no errors within 10min runtime, Lockout works!
Colorful „Rainbow“ Beacon => no errors within 10min runtime, Lockout works!
Colorful „Voltage“ Beacon (blinking purple = full battery) => no errors within 10min runtime, Lockout works!
