I recently won a TrustFire Minix and have been asked to show it, which I’ll gladly do.
Fig. above, left to right: Nitecore TIP CRI 2017, TrustFire Minix, Fitorch K3 lite
The Minix is a keychain light with a 300 mAh battery and up to 320 lm. It is available in two versions each with a white (5700 K) and either a red (620 nm) or an ultraviolet (365 nm) LED. I like both versions for their use value: The red LED can be used as a beacon while the UV LED has the right wavelength for testing bank notes and documents. So, you have to decide which one is the right one for you.
I got a grey one with UV aux light, and am happy with it. The UV light is really weak, so no headache when using it without protecting glasses (I’m really sensitive here).
Interestingly, the UV light has the blink mode of the red version, so the same firmware is used in both lights even if it doesn’t make any sense. But it doesn’t hurt either.
I’ve measured 5700K, CRI 70. The color rendition is good, I first thought it could be HCRI until I measured it. The beam has a range of 86 m on High, so it’s an all-purpose beam. The spot is not entirely round, also there are rings. Honestly, this doesn’t matter much in the wilderness™.
There’s no PWM in Moon and High. The Low and Mid modes are generated by means of PWM, but at about 15600 Hz I do not notice it.
The UI is very simple: A 0.5 s press brings up white light with mode memory, 1.5 s and you have the auxiliary LED activated. Subsequent clicks switch through the modes. I wish there were no mode memory since there’s no direct Low, but I guess switching it back to Low before switching it off does the job, too.
The light is locked by double-clicking from off. Another double-click unlocks and activates it at the same time. So, it is quite a fast action :THUMBS-UP: .
A single click from off shows the remaining battery capacity (RG-LED in the key, refer to the manual page pictured above).
The Minix features an intelligent temperature control, which is quite unique for small keychain lights. Also, the manual states there’s a low voltage warning. Not sure if it actually offers a LVP.
Charging (USB-C port, cable included) takes one hour. When I watched it, my USB meter showed a max of 410 mA. The Minix was nearly fully charged when it arrived. That makes sense as there’s no way to decouple the battery from the draining electronics, and stocked lights will discharge over time by necessity.
Runtime diagram on High:
Right axis show temperature in degree Celsius. Sorry, forgot it.
Yeah, runtime as stated, excellent temperature regulation. TrustFire can do it :THUMBS-UP: . After 75 Minutes, this thing still was on a good low level.
Thanks for reading.
