Anyone know if this is bright enough to read by?
I may have a different brand but I have something very similar and it is bright enough to read.
What type of battery does it use?
“Provides up to 7 hours of lightning”
Wow! What kind of battery can power that!?
Thanks for pointing that out. 
saved me a few bucks.
Heh. Someone has been typing lightning cables too many times. Fixed.
are batteries rechargeable? replaceable? or once and done?
Thorium batteries?
