Acebeam K30 or Imalent RT70 ?

RT70. Because it has a larger reflector diameter, and therefor more throw. Bigger is what's better. Smaller = Less.

If you want it to work forever, Acebeam

They are very similar lights in output & beam performance Price as well.

Imalent’s customer service seems to be decent about replacing failed parts within the warranty. That’s harder to tell with other brands because they don’t break as often.

LOL

It ends up being neither.
