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:

Best AA flashlight!

Over the years I developed a fascination for flashlights. I am always looking for the best combination of features, form factor and practicality out there. I believe this flashlight is best in class in all categories. Some of the great features include:
1)Excellent user interface
2)Great battery life (easy to get AAs)
3)Flexibility with battery chemistries
4)Great emitter with nice flood pattern
5)Great weather resistance

The craftsmanship and materials are superb and the flashlight feels great in the hand. As a bonus Benjamin is a great person to deal with and very responsive if you have questions.

Fantastic light

It's perfect to carry in any type of pants or shorts. I liked it so much I pre-ordered a second

Blown away

I’m glad no one had to hype this light up for me, I came into the purchase not knowing much about Ben and how great he does machining his parts and how much pride he takes in his products. I just seen a cool light one day and figured I wanted one. When it came in and I started using it for my carry on grave shift at work, I swear it out performed in ways I didn’t expect, the user interface is easy to work and figure out and it puts out a nice flood of light and it’s pretty bright even when I don’t have it on the highest setting. If anyone is on the fence about spending the cash to get an S2, I’d say it’s well worth the price when you can get one.
