I just got a FandyFire STL-V6 (from Wallbuys) late last week, and while it seems that this is an older light, I had great expectations for it as far as throw and lux. I had posted in an older thread about it, but I thought that I’d start a newer thread to try to address primarily the performance problem.
There is a “functional” oddity with the STL-V6 that I got, i.e., I can’t get it to switch into the 3-mode group, and between that and the disappointing lux numbers, I’m starting to suspect that maybe there’s something different (and worse) about my STL-V6 vs. the ones that others got before.
I’ve been doing lux measurements, at 4.3 meters, and the numbers I’m getting are 1/2 or less than those that I get for an HD2010 (with the original EAST-092/direct drive driver). For all of the tests that I’ve done with the STL-V6, with different batteries, including pairs of fairly new, freshly charged Efest IMR batteries (
4.20V), are coming in around the 1500 lux ( 4.3 meters) range.
So, I was wondering, if anyone has an STL-V6, could you tell me if the driver board on yours at least looks like mine:
P.S. The mode group thing also is bothering me, so if anyone has any ideas about that, please let me know?
Edit: BTW, can anyone tell me how to convert that 4.3 meter lux reading to 1 meter lux reading?
