According to gchart’s test the pro held around 300-400 lumens for like 3 hours [Review] Sofirn SC31 Pro - now with Anduril & USB-C
. Definitely not as bad as my first impression, and considering all the other features this light has to offer, I may have one coming my way soon.
Of course better regulation could be had even in that size of tube light, like with the sp31 v2.0 or sp32a, which are basically the same size (in diameter) as the sc31 pro, but they can sustain over 500 lm for a few hours. Of course they are totally different drivers and don’t have the other features like usb-c, Anduril, so there’s always trade-offs.
