I received the Rofis G01 from Rofis for the review.
The Rofis G01 is a weaponlight, featuring a XP-G3 CW emitter and powered by one CR123/RCR battery.
The G01 comes in this cardboard box.
The G01, screw, screwdriver, O-ring and the CR123 Primary battery that comes with the light. Not shown: manual and warranty card.
The whole light is made out of a single piece of aluminium. Body of the light and rails are the same piece, the only removable piece is the tailcap (the head is glued to the body).
The head is glued to the body with threadlocker, and hosts an XP-G3 emitter in a smooth reflector.
The tailcap has millings that help the grip when twisting and untwisting it.
The spring in the tailcap is quite thick and hard to push. It is surely nothing like the spring of a regular railcap.
The threads for the screw are anodized and keep the screw tightly in place.

UI
The light has 2 modes: constant output and strobe.
A short ( < 0.5 seconds ) pressure will turn the G01 on with momentary function.
A long ( > 0.5 seconds ) pressure will turn the G01 on.
When the light is on a short ( < 0.5 seconds) pressure will activate the strobe.
To turn the light off, it requires a long ( > 0.5 seconds ) click.

Output and runtime
Tested using a Panasonic CR123 Industrial and an Olight IMR Protected 650mAh battery.
Notice that usually I don’t do runtime plots with primary batteries, but this one was provided with the light so I used it for the test.

My thoughts
The light is well built and finished. It is hard to make a more sturdy light than the G01, since it the body and rails and the mount are made out of a single piece of aluminium.
Running the G01 with a RCR battery will give you more output, but semi-regulated and without a signal of low battery. Keep in mind that unprotected RCR will be overdischarged.
Running the G01 with a CR123 battery will give significantly less output: only 160 lumens, but with a much better regulation (2 hours of flat output, followed by 30 minutes of diminishing light and a prolonged time with a few lumens).
The beam is fine, and the target are well illuminated as you see in the beamshot… that I did with the RCR battery. Keep in mind that using this light with CR123 battery, you will have around 1/3 of the light.
I don’t own a gun and I have no experience at all on weaponlights
I tried to simulate the recoil by beating the tailcap and the front of the light on a hard surface without seeing any malfunctioning.
Operating the light is a bit tricky, because the momentary on can be used only for 0.5 seconds before becoming full on; so momentary on consists only in brief flashes (maybe useful to signal your position or communicate). This also mean that to turn on the light you need to keep the switch pressed for more than 0.5 seconds, you can’t simply “tap” it.
So, as far as I can tell:
this light works fine with a RCR battery, except it lacks an evident signal of low battery (the PCB trips and stops the battery without any signal, only the diminishing brightness can tell you so), but it could benefit of a better regulation.
With a CR123 the light output will be significantly lower, but you have more runtime and a signal of low battery. The light could benefit of a higher output, even if it will translate in lower runtime.
Thanks to AntoLed for the camera advices and the luxmeter, Zampa for the tripod.
