Some time ago I bought Powerlight HX-G011 1W 1xAA LED Flashlight Grey. This is a very useful and cheap LED flashlight. It only uses 1 AA battery, which is really is great. Light is quite bright for the price (feels like between my other old 1W LED flashlight and new 1W LED flashlight) with nice spread beam. The light output is a bit blueish color, but nothing too bad. The body really does not feel like less than 4$ flashlight.
There is one issue: specifications. It seems that you can’t rely on those Chinese specifications. The product description describes this as 1V, but the Powerlight flashlight I received is imprinted, and indicated ’3W’ instead of ’1W’. What is the reality? This needs to be tested.
The reality seem to be that neither of the specifications are right (I did not expect them to be when I bought this). When I measured the flashlight takes around 400 mA of current from AA battery. That translates to around 0.6W of power. Taking in account the losses of the switch mode power supply that generates the needed around 3V power for the LED, I would not expect that LED would get somewhat less than 0.5W of power. So I would expect the real power figure for LED to be around 0.5W or less. This is far from 1W or 3W specifications!
If you can ignore the fact that the specifications are not right, this Powerlight HX-G011 1W 1xAA LED Flashlight Grey product feels like a pretty good product for the price.

I found one minus on mechanical construction.
The battery started to make bad connection after more than half year of use. Later when the lamp was dropped, the battery + terminal near the LED became loose making the lamp broken. The lamp construction seems to be such that it seemed pretty impossible to repair it.

LED flashlights are really great because they do not consume too much electricity.*
