I've got about a half dozen of the AAA Synergy1, so yes I'm a Frelux fan. This is my second Synergy2. When the Synergy1 doesn't cut it in output (which is rare), run the Synergy2 on Lithium ion and you get a crap load of light. I've got alot of custom lights, the Synergy1 and Synergy2 are great.
Agree with previous reviewer that the firmware / controls here are better than the Synergy1 (although no complaints there).
Disagree with previous viewer on initial set of batteries - Alkalines leak, I won't store them in light, so it's NiCads or Lithium/ Lithium Rechargeables. I've got plenty of both.
The RWB (Red White Blue) - hell yeah!
I much prefer the firmware in this model over my previous purchase. I do feel a purchase of this caliber of flashlight, should come with an initial set of batteries 🔋🔋. Just my opinion as a fellow maker of expensive little stuff. Thanks
