The LED will finish off the batteries in no time... 9V batteries have a pretty low capacity.

18650 batteries or 12V Lithium-Ion batteries could be way better (Check them on eBay, They're really cheap)

sure!! depending of usage ......(https://en.wikipedia.org/wiki/Nine-volt_battery).

in my case,have light for one hour....(maybe is battery at 300 mAh...)

this led need 275 mAh......We can build a battery pack with others battery keeping in mind the type of usage you needed...!! emergency lamp(short time)

exploring lamp or diving lamp(long time)....
