These lights really need a wide angle lens to keep the light out of oncoming traffic's eyes. Order it separately.
Typically lumen claims like this are LED lumens, meaning for a very brief period at turn on, the light is theoretically capable of producing 1200 lumens at the LED.
However, there is sometimes a quick drop in output with-in the first few minutes, and after taking into consideration reflector loss and front glass cover loss, you're probably looking at anywhere from 20-40% less than the manufacturer's claim
This one has is customized with a wire coming out the back to a battery pack.
This is the right place to mount lights
This one is the best I have seen with LEDs and NiMH rechargeable 5 hours on four AAs
A flux of 1000 lumens, concentrated into an area of one square meter, lights up that square meter with a luminance of 1000 lux. However, the same 1000 lumens, spread out over ten square meters, produce a dimmer luminance of only 100 lux.
Achieving a luminance of 500 lux might be possible in a home kitchen with a single fluorescent light fixture with an output of 12000 lumens. To light a factory floor with dozens of times the area of the kitchen would require dozens of such fixtures. Thus, lighting a larger area to the same level of lux requires a greater number of lumens.
The projected beam is brightest at the top, and is progressively dimmer towards the bottom. This results in amazingly even illumination of the road surface ahead, unlike so many other headlights you'll find in bike shops that are really just flashlights with a handlebar mount.

Does it blind drivers in the opposite direction lane?

A 2200 mAh pack can be charged up to 2.2amps, but I do not recommend more than .33 amps per cell in series in the pack.
