Nowadays Many Torches feature at least 500 Lumen,
My Group lost me before when i was too engross with taking pictures, but the boat man managed to find me on the surface when im using my 2.6K lumen under the water.
And of course, reliability should be one of the top concern on getting your new lights.
Yes paralleled importers can offer a very attractive price, but they rarely offer after sales services.
Sometime if you can get it so cheap, you wont not know if the torch you holding had pass the Factory QC.
I do advise if you need some lights, pls get it from someone who can offer you warranty and after sales.
at least you can get back to him/her when the lights spoil. And also when Sh*t happens, you wont wanna get caught by surprise, that the very thing can save you fails
