The Acebeam ed50 kinda looks like a r50 too. I have guided people away from the R50 to the Lumintop. Personally I think its a better light than the R50.
Got my ODF30C yesterday. Very powerful light, I'm impressed, especially the bump up in brightness in turbo, but unfortunately mine has a faulty switch. Around 70% of the time it won't respond to change modes, or won't even turn the light on or off. I need to loosen the tail cap and tighten again to turn it on or off and it is not in lock out mode. When switching modes, most of the time it stays in the same mode and won't go up or down. Often when in medium or high, it just turns itself back to low as well without touching the switch.
I have got similar switch behaviour on ODF30. Contacted Banggood, they offered me to find a local repair service Let’s see how this will continue, after I explained the the light is glued all over :person_facepalming:
Hate when they talk about "local repair". Never had a good experience once that starts. Usually comes back worse, not changed at all or all banged up and scratched. I ordered another ODF30C last night as I really like this light. Hopefully that one will work. I'm pretty sure it is going to be a very long, frustrating and drawn out experience dealing with Banggood with my faulty one.
