Hallo guys, I am new here and I am just mountain bike lover. I am not into electronics as much as you here, so I just came for advice. I am from EU, currently looking for decent bike light for trails (rought terrain, downhill stuff etc., bikeparks are closed 
). In my country there is good access to some Chinese brands. I found Gaciron RAPTOR 3000 (3x Luminus SST25, 2x21700 5000mAh) or GACIRON V9DP-2000 ( 2x Luminus SST40, 2x18650 3350mAh) for quite nice prices here. I don´t want to pay for Lezyne or other bike brands, they dont provide LEDs info or cell capacity/type, overall value is lower. What are your opinios on the listed lights and do you have any other tips? My preference is higher efetiency (so CRI 70 is OK, colder light temperature is OK), and that also means adequate cells. Thank you.
My first light was a Leyzne overpriced and under performing. Good idea not buy those.
I use the Fenix BC30 version 1, it uses two18650 cells which needs a separate charger (more money).
I like it and have been using it for years.
Try MagicShine
I think there is an EU distributor , I’m in the US.
I am also interested in Raveman
Banggood has some appealing looking lights too.
When looking for a decent bike light pay attention to the mounting method, The light mount is half of the bike light equation, I for one do not like the rubber stretch mount, I found they do not hold the light steady enough when mountain biking.
I’m not familiar with those two you mentioned, If the price if reasonable (to you) than just go for it and have fun.
The thing I found with bike lights you could spend a lot and get very little, or you can spend a little and get a lot.
The last sentence is what I am worried (spend a lot and get very little)
Those listed light are around USD 100. I know MagicShine, but they are 2-3x more expensive (3500lm is around USD 200 in my location). Gaciron should be the brand which is making lights in the same place as Lezyne, so the machining quaility should be ok.
Gaciron is okay, particularly if you buy it locally, more likely to get some kind of warranty. It’s gonna cop a lotta thumping and vibration on a mountain bike…
Which light did you get?
