I use the
Mighty Bright TravelFlex.
It's slimmer and lightweight compared to the regular Mighty Bright XtraFlex 2 light.
It uses only one AAA battery.
I attach the light to the middle of my Kindle case and it works really wells.
I also own the Mighty Bright XtraFlex2 but it's too bright for me. I use it for a nightlight instead.
I'm still looking for a light to use in bed that doesn't bother the person next to you. I bought the lighted cover but Hubby complains when I use it so I use the Travel Flex for now but sometimes when I am shifting positions he growls at me.
