Synergy2 RWB

Regular price $250.00 Sale

The all new Synergy2 EDC flashlight is a result of over two years of development. Each light is made with care and pride by just one person, raw stock to finished product. This light has proprietary Frelux™ electronics and firmware. Everything that could be made in the USA was made in the USA including the PCBs. While similar in form factor to the Synergy1 it is different in all other areas. Its an AA / 14500 based light with the following features:

  • Machined from 6061 USA produced manifold quality aluminum
  • Samsung LH351D 5000k 92 CRI LED
  • Frelux™ multi-chemistry multi-voltage high efficiency constant current driver
  • Frelux™ ramping user interface with memory
  • Physical Reverse Polarity Protection
  • Low Voltage Protection (Both cell types, temporary override capable)
  • Over Temperature Protection (temporary override capable)
  • Adjustable tension, ambidextrous titanium pocket clip
  • Physical button lockout
  • Waterproof (tested to 8ft deep)


Candle Power Forums review from Devin

Technical review with more specs than you can shake a stick at!

Below is a compilation of videos from my Instagram account @Frelux which you should follow for the latest information.

At the time of the first pre-order I have not had the light third party tested. The estimated output numbers based on spec sheets and current draw are the below. Because of the "infinite" modes of the ramping firmware I will list the highs and lows.  I will update this page and the manual when I have more data. Anecdotally with daily carry I have seen about 6-7 days using 1000mAh 14500's and close to two weeks using 2450mAh eneloop pro Ni-HM batteries before needing a recharge.  

Tested and confirmed compatible batteries:

Second Synergy2 - Wanted the RWB

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!

Awesome flashlight!!

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
