I just received my Acebeam E70 and thought I'd post my thoughts on it.
I ordered this pretty early on before the 5000k emitter or stainless steel options were available, so this is the 6500k aluminum version. This uses the XHP70.2, which I'm a huge fan of because I like my EDC lights to be floody. I had the Thrunite T2, but the side switch was prone to accidental activation so I began looking for a solution. I have been carrying the Meote FM1 in a hard holster, and that mostly solved the problems. But, it's kind of heavy, especially for an 18650 light.
Enter the E70. It runs on a 21700 battery, which I prefer because I don't have to swap cells in the middle of the night. The XHP70.2 is more than adequate on medium or high, but turbo is stupid bright. I don't mind the cool white 6500k emitter when I'm gaining some output and efficiency. I have a 4000k T36 with me if I need more distance and higher CRI.
So, the battery. This is my only issue with this light. I have the Acebeam branded battery with the integrated USB-C charging. Other than being pricey, there's nothing wrong with this battery. The problem is that the springs on the inside are quite short, especially when compared to the T36 and L35. A flat top 40t does not work in this. It will turn on, but if you move the light around at all, it breaks connection and the light turns off. You can use magnets, or whatever other tricks to lengthen your 40t, but a standard flat top will not be acceptable as is, it's just too short.
That's the end of the negatives. I'm loving everything else about this light. The run time, the ability to produce a WALL of light from a flashlight this small, the fit and finish... it's all there. The UI might divide a lot of people, but this has a double click for on. Frankly, I love it. I can carry this loose in a pocket, in a soft holster, however I want... and it won't burn a hole in my pants. I use my flashlight at work a LOT and for that reason it's not practical to carry it locked. Well... I don't have to worry about that ever again. And the double click for on is worth it for the peace of mind.
Also, the styling is unique and cool... it's not boring like a lot of other lights. I appreciate the effort they took to make it look special.
I think they hit a home run with this, and I really like that they aimed to solve the accidental activation problem. I'm pleased.
