I received the Usignal from BangGood for the review. Here’s the purchase link: CooYoo Usignal XP-G2 160LM USB Multifunction Mini LED Keychain Sale - Banggood Deutschland sold out-arrival notice-arrival notice
The Cooyoo Usignal is a small, compact (59mm x 10mm x 23mm) , prism shaped flashlight. The light features a CW XP-G2 emitter, a 5mm red and one UV, all powered by an integrated li ion battery (280mAh), rechargeable via micro USB.
I’d like to introduce my mailman to the Olympic specialty of package throwing. That package was found several meters from my gate onto my propriety. It was thrown and landed, Usignal first, on concrete, damaging both the box and a bit the head of the light.
No accessories or manual. Nothing in the box, but the Usignal.
Prism shaped, with an integrated splitring design. On one side the micro USB port for recharging the battery, covered by a rubber port cover.

The UV LED does its job, with quite some purple light coming from it

Output and runtime
My thoughts
The light is well built and finished. I like the form factor of the light, discrete and practical (although the rounded design of the bottom makes tailstanding impossible).
I like the form factor of it, with the single electronic switch on top of the light, easy to find and grippy.
I like the concept of the 3 different beams, but in practice the red LED is very dim, and having just one constant output mode, it makes it less usable.
I don’t like the PWM on the main LED, and the lack of an electronic lockout. Also, even with long nails it is very hard to remove the micro USB port cover from its socket, I need to use a pointy object like a toothpick.
I’d like to see this light come with a small sheath and a NW tint.
Thanks to: AntoLed for the camera help and the luxmeter.
