This particular version of the Synergy1 Flashlight is called the BFG (Big F'ing Grip). Its got all the same great features of a normal Synergy1 but has a new rough and tumble matte anodized finish and extra grip milled into the center and front sections of the light body. You can choose the LED, clip, lanyard loop and color combination you want. The Cree is a higher output cooler temperature LED and the Nichia has a slightly lower output, warmer temperature and higher CRI.
I designed the Synergy1 because its something I wanted. I used to carry a small AAA Streamlight and after a few years it finally just fell apart. After looking online for something new and not finding anything small and pocket-able that caught my eye I decided to design my own. As I went through the iterations it became apparent the side by side form factor was a good one to make something unique. So not only is it an interesting looking light its also modular. Its a 2x AAA light with a reverse clicky button on the front and has low-medium-high modes. It is o-ring sealed front to back, modular allowing easy user customization, and has an optional clip that works on either side of the light. Every part of the light body manufacturing process as well as the titanium clip is handled in house, right here in the USA. It does however contain some internals from overseas, but I have taken the time to build good relationships directly with the suppliers of those to ensure the utmost quality.
The mode order for the new driver is: Low - Medium - High The light powers on to low and you "half press" (no click) to cycle the modes. Alternatively if you fully press (click) in succession it will also cycle the modes.
