Top 5 Positive Customer Reviews for sofirn
Nice flashlight. Threads are very good. Not thick aluminum but good for the price point. Here's what I like. It starts out in moonlight mode. And it's very dim but that's fine. If you're in a tent or bedroom low is better than high. Just hit the button and it goes to the next mode. Turbo is great. Have not tried it yet outside but will. MOST important to me is the lockout mode. Four quick presses of the button locks it. Got to have that in a pocket side button flashlight. High marks for this Sofirn. I recommend it.
There are legitimate BLF Q8 MCPCBs, as they are well 38mm wide and 2mm thick. The wires are also 20AWG, so quite thick. The back is a bit oxidized, but nothing that sandpaper can fix, especially since copper does oxidize quickly. All in all, a very good genuine MCPCB for those which want to change the stock 5000k XPL LEDs for others like Nichia 219Cs or Samsung LH351Ds without having to reflow and remove the original LEDs. Finally, the pictures are accurate to real life.

Thanks for Reading. Splott :-)
This is exactly the driver used in the BudgetLightForum group buy, surprised to find this driver and glad I bought it. A comparatively simple installation into the SF34 netted a whopping output gain to over 5000 lumens... the construction of the light is unable to cope with this much gain though so I took steps to handle the heat by turning a heat sink that I secured with the MCPCB sandwiched between it and the reflector and appropriate thermal paste installed. Great driver, attractive price... can't go wrong here! :)
