Package contents and impression<\/strong><\/h2>\n\n\n\n

The light comes in a typical white small Sofirn Box. It Includes the light itself preloaded with a 900mAh 14500, a lanyard that is similar to that of the Wurkkos HD03, a multilingual manual and a tiny USB C - C cable.<\/p>\n\n\n\n

\"\"\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n

The light is surprisingly heavy for its size, 48g without and 69g with battery.
n comparison, a Oclip pro is 52g, a Wurkkos HD03 is 48g, both of course including the battery.
The light feels really sturdy and well made, i couldn\u2019t find any flawy. The anodization is matte silver\/grey, smooth and even. Doesn\u2019t provide tons of grip, but enough for a light that size. There are no sharp corners..<\/p>\n\n\n\n

The tailcap is slightly bigger than the body, which seems a bit odd at first, but it really helps unscrewing it and doesn\u2019t bother me at all - its just not enough offset to catch anywhere in a pocket.<\/p>\n\n\n\n

\"\"\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n

There is a magnet in the tailcap and in the clip, both strong enough to hold the light.
If you use the one in the clip, the light tens to rotate bezel down, because the magnet is in the lower end of the clip. That isn\u2019t really avoidable, just wanted to mention it.<\/p>\n\n\n\n

On one side (looking at the clip on the left) there are two button under one rubber cover. they have a groove in between, but they are the same height. Not good with gloves, but that is no tactical light, it\u2019s allround EDC - so this is fine for me.
Between the switches sits a little battery indicator (green 100-30%, red 30-10% and red blinking 10-1%)<\/p>\n\n\n\n

\"\"\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n

The lens on the top has a frosted look with some rings in it and is, as far a i can tell, not covered with glass.<\/p>\n\n\n\n

\"\"\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n

The lens on the side is interesting. It has a almost orange peel like structure on the inside and some ridges on the outside. It covers both leds and is not covered by glass, you can feel the ridges, similar to the Wurkkos HD03.<\/p>\n\n\n\n

\"\"\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n
\n\n\n\n

Carrying options<\/strong><\/h2>\n\n\n\n

Clip: the Clip is sturdy and holds the light very firm, the rubber helps quite a bit. It\u2019s not at all a deep pocket clip, but you won\u2019t loose the light. To open the Clip, you will press on the lens. Not a problem an necessary to be usable on a cap. Be aware that the clip sits on the thickest part of the light. That makes it seem bigger in a pocket than it really is - or it rotates about 90\u00b0 in you pocket and sits just fine. Ok for loose pants, if you wear skinny jeans it might not be the most comfortable.
Lanyard: The lanyard is well made and offers various options. The mounting hole is on the clip. That\u2019s nice, if you hang the light e.g. in a tent, the sidelight will point about 45\u00b0 down.<\/p>\n\n\n\n

\n\n\n\n

UI<\/strong><\/h2>\n\n\n\n
\"\"\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n

In general, the UI is thought through and works well. Only the red light control is not my favourite, because the logic changes.
Hold for on is fine, click for mode change and hold for off is confusing - at least if all other modes are the opposite.
But as always if there are multiple lightsources on one button, it is a compromise. I caught myself changing modes instead of turning off not only once, definitely something you have to get used to. Overall, i would say white UI is fine, red UI is inconsequent but usable.<\/p>\n\n\n\n

I still would have preferred triple click to red and hold for mode change, because shortcuts to moon and turbo on the side light would have been possible with this. On the other hand, holding a button is less likely to end in a click than triple click to end in a double click, blazing white turbo out instead of red.
I can live with it after a bit of familiarization, but I would still like to see a different solution for red.<\/p>\n\n\n\n

\n\n\n\n

Beam profile and measurements<\/strong><\/h2>\n\n\n\n

The front light is floody with a huge, diffuse spot and little spill.<\/p>\n\n\n\n

\"\"\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n

The side light is nearly pure flood, just a bit shaped.<\/p>\n\n\n\n

\"\"\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n

The red light is similar to the white side light in profile and really bright. One of the brightest reds I have had in a light.
My personal favourite is the doubleclick-beacon. Bright enough even as a daytime warning light (not in blazing sunshine though).<\/p>\n\n\n\n

The front light showed around 800 lumens on my (not at all calibrated or exact) lumenbox, the side light was a good 500 lumen.<\/p>\n\n\n\n

There is no regulation on any mode (both diagrams show turbo):<\/p>\n\n\n\n

\"\"\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n

After around a minute of turbo the front light drops off fast to around 300 lumen. From there is slowly goes down to a bit under 200 lumen, this takes about 105 minutes. After that, there are about 20 minutes with usable but not bright light left before it shuts down.<\/p>\n\n\n\n

\"\"\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n

Side light shows similar behaviour with on additional stepdown.<\/p>\n\n\n\n

My Opple Light Master III shows 6800-7000k for the front light and 6600-6800k for the side light. Both are low CRI, around 70. Both lights are dead neutral, DUV 0,000 \u00b1 0,001!<\/p>\n\n\n\n

The battery ended charging at a healthy 4,18V and is nearly identical to a manker one I have. Perfectly fine choice for a light like this.<\/p>\n\n\n\n

\"\"\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n

Summary<\/strong><\/h2>\n\n\n\n

If Sofirn wouldn\u2019t have provided this light to me, i would have missed out. Just from the specs, it wasn\u2019t appealing to me.
Now that i used the light for some days, I really like it. Walked my dog with it, worked on the car and carried it as EDC. Good magnets, cood clip, good brightness. Battery is exchangeable, dual fuel is possible. Amazing red light. And the beam profiles are perfect for most EDC tasks.
There are negatives, too. I wish the side light was warmer and maybe high CRI and the red UI was more in line with the white UI.<\/p>\n\n\n\n

But for the last days, it ended up in my pocket nearly every day. A big part of that is because of the great build quality - its one of the lights i really like having in my hands.
It might be because I had little expectations, but I really like the ST10 better than the Wurkkos HD03 and the Oclip Pro!<\/p>","protected":false},"excerpt":{"rendered":"
