A new brand of flashlight has hit the street...
May be some have noted that I have a preference for ring controlled flashlights. In my opinion, the control ring will become the standard for controlling the functions of advanced flashlights.
When, if we will ever see that day, the "advanced" flashlights will be commonly available at supermarket shelves, and not only on selected websites, they will all have a selector ring. The "Average Joe" will never deal with multiple clicks, timed presses, and fast head rotations, not to mention programmable lights.
I have noted that Sunwayled flashlights mostly uses a control ring in their flashlights. I'm very happy to see that a newly born flashlight company oriented toward a choice that, in my opinion, is the only sensible choice for advanced flashlights.
I am looking at their smaller models; namely, the M10R (single 123) and the M20C (two 123).
The first thing I noted is the fact they use R2 binned, XR-E LED. Outdated? Yes. Relatively low brightness, relatively high Vf and low efficiency LEDs.
I believe Sunwayled values throw above runtime and brightness. OK, I can survive to this.
Let's now see some other aspects. Consider the M10R. I read the specs from the website, I may want to buy one. Then, I stop to the voltage specification of the flashlight: 0.9 to 3.2 V. I check the suitable battery for it: CR123, no mention to rechargeable Li-Ion.
I have the JetBeam RRT-0, and the Nitecore IFE1: did I mention I am ring-haholic?
The RRT-0 is happy with every AA or CR123 of every chemistry, primary or rechargeable, I can place in it. The IFE1 will accept only CR123 sized batteries, but it will work with any voltage from 0.9 to 4.2 V.
Now, back to the M10R. Has any fellow CPF member bought one yet? Can you confirm it will work with Li-Ions?
If not, I may want not to consider buying it, as it would mean Sunwayled went for a futuristic interface, but for an outdated LED, which is still OK because of its throw, but I can't accept they used an outdated converter.
I apply the same reasoning to the M20C. I see in the voltage specification: 4 - 10 V. The specs says that the M20C is bored for a 18650 cell, but the voltage specs says differently. With the Vf of a R2 LED, an high efficiency buck converter will not keep regulation down to 3.3 V, you need a buck-boost converter.
Now, for who has already bought a M20C, does it stay in regulation, on high, until the 18650 is depleted, just like the Jetbeam RRT-2 does?
In any case, I'll stay tuned for reviews of the M10R and M20C.
