Acebeam, a brand never afraid to push the envelope and release multiple iterations of lights (a la the TK16 with multiple metals and emitters), has released the H50 headlamp.
Acebeam has been on a roll with triple emitter lights lately. The TK16 was a very popular small e-switch light, for example. Out now is a much higher output 18350 light, the TK17.
Acebeam recently released a copper pocket light that really sung to enthusiasts. It's a 18350 triple, available in three different emitter options. That was the TK16. First available in copper only, later released in aluminum. Today Acebeam released details of an upcoming big brother to the TK16. It's the TK18, which looks to simply be an 18650 version of the TK16.
The Russian company Yarkiy Luch aka YLP, has introduced a new light named the Unicorn 1.0.
