The RAYUS U10 is a programmable flashlight with multiple selectable operating groups. Users can choose their preferred operating group, set the default output mode, and enable/disable the memory function. Built-in intelligent USB charging allows for quick, reliable, and convenient power management. A single side switch allows the user to select among the 5 output, Strobe, and SOS modes. Equipped with the latest intelligent thermal management system, the U10 can dim Turbo brightness gradually to keep the light within safe operating temperatures ensuring preserving the LED and internal electronics. A hidden power indicator is also accessible so you won’t be left in the dark. The U10 is compatible with a wide range of power sources such as CR123A, 16340, and 18650 rechargeable batteries. Water resistant to IPX-8, the U10’s compact size, light weight, and feature packed interface make it one of the most versatile lighting tools on the market.
Thanks so much, saypat
One of the only manufacturers smart enough to put a nichia emitter in a light.
That and interesting drivers is a good sign that they are listening to what users want .
Thanks, Boaz
That is very nice.
I would like a zoom though.
When I need a spot function at distance I don’t want any spill. I want a very tight beam . Conversely, when I want a flood, at low or very low output of a few lumens, I want a very wide beam. A diffuser works, well for this too, but a standard cover type is too easy to loose, and a flip up one gets in the way.
Thanks, Neilp
