yes!just BS.
SilverFox's testing leads me to believe that even the best AAA NiMH cell under a load of 4.7 amps will have a maximum capacity of around 300 mAh - if it doesn't fall flat on its face like most will. Average voltage would be ~0.92 V.on the other hand: with 3 AAA batteries you will get a runtime of 1,2V * 1000mAh = 1.2W /17W = 4,2min
17W is totally for real, it's a "model number" only, 17W doesn't mean 17 Watts, it means we want you to send us money for a cheap light that some people think has 17 Watts of output and runs for a long time on 3 AAA batteries. Of course it doesn't have 17 watts of output and they don't say it does.
