Well made and robust little torch that has a good throw of light

This is a rather basic, rechargeable flashlight with zoomable head.The light charges via an USB-C port located in the tail of the light. Unfortunately it does not have a replaceable battery and the capacity of the internal one is not specified.The flashlight has two separate LEDs - one cool white and one blue. User interface is very simple and is controlled by a single electronic button on the tail. Press once for white light, press the second time for blue. Next press turns the light off. No blinking modes, no strobe, no different brightness levels.The head of the flashlight can be moved forward and bakward which can zoom the beam into a fairly tight spotlight. The white and blue LEDs are not centered in the lens and do not "point" to the same spot, but that's noticeable mainly when testing on a nearby wall.The full brightness is achieved in the zoomed out position, as you zoom in, the total output lowers due to optical losses, but the hotspot of course gets smaller and brighter.The white LED reaches about 100 lumens and holds it 1 minutes before starting to stepping down. Over the next 3 minutes the brightness lowers to finally settle at just under 40 lumens.That step-down in brightness is quite unnecessary as this is a low output light that doesn't even get warm when running. The circuit initiates the step-down based on a timer and if you restart the light it comes back at full power.The light comes in a small plastic case and includes a USB charging cord.Overall, if you need an inexpensive (under $20 at the time of my order) flashlight with blue light this one is allright. If you need one for work backstage or in a cinema I would consider taping a blue gel to the lens - this way instead of white / blue light you'd get blue / dimmer blue which would proably be quite allright.For hunting / tracking this light doesn't have enough output and non replaceable batteries can leave you stranded.Blue lights aren't the most common, but if your budget allows, then there are several excellent flashlights with blue emitters available online, with much more customizable light modes and replaceable batteries.
