Pic 4 says it has 4*7135 chips which is 1400mA. Half of what the brightest (8*7135) ones use. The Nichia 219C is also less efficient than most Cree and some other LEDs.I think 468lm sounds about right.
An honest 468lm is still very bright, and Convoy specs are pretty accurate though.
You can try Googling "Convoy S2+ 468lm review" (without the quote marks) to see if it's been reviewed on one of the flashlight forums. Very good, accurate info there.
Btw, to link an sku #, just type skuxxxxxxx (no spaces) and it will be linked automatically.
SKU 9687365I forgot to mention that runtimes will be longer with less lm, and the battery capacity can make a difference too. Avoid the super cheap Chinese batts like Ultrafire etc, and
any batts with stripes on them like those below. vv
