We don't read in bed but I am sure they would be bright enough to read by comfortably. I use ours frequently when I need to get out of bed for some reason in the early morning and my wife is already up. The web site says they are 190 lumens but that doesn't mean much to me.
Also use them anytime a bright light is needed while sitting on the bed doing some task. They are much brighter than the overhead light and the light is focused. They are also a very convenient reach to turn on or off rather than having to get up and go to the wall switch or reach up to the ceiling.
Edit: I just went to the website and read some of the reviews for the light. Most loved it and said it was perfect for reading. Maybe I should start reading in bed!:B
