AA只是個size,普通的aa電池達不到600,有200也算好了,要AA size的14500鋰電池才行,那塊電池比你電筒貴 ...
你的说法比较靠谱
我网上找了测评:
Beamshots
I equipped each of the 3 lights I got with different batteries: the first one with a fully loaded 14500 li-io battery (efest IMR 700 mAh), the second one with a freshly charged AA Eneloop (the “old” white ones) and the last one with a new AA Alkaline battery. The X900 is advertized as a max 600 lumens light, so I chose another zoomie in the same lumens range for comparison; it´s the LED Lenser P7.2 with a high mode of 250 lumens and a low mode of 40 lumens ( I did not use the “boost” mode with 320 lumens).
So here we go, first shot is 3 meters from a flower wall, all pictures have been taken with the same settings (Canon DSLR, 2 seconds, Iso 400, f/ 5.6, 24 mm focal length, 5000 Kelvin)

When direcly compared, I would estimate the real lumens of the 14500 version around 400 lumens, which is pretty solid for such a small light. You can also see that the tint of the LED is not too cold, it´s a neutral white a bit on the cold side.
