How do you make a cordless table lamp? Answered

Hi my son has a project, he needs to design a cordless table lamp, what are the considerations he need to make to how he powers it, what size rechargeable battery, what charger will he need, how bright will the LED bulb be, how long will it last before the need to recharge, any other considerations?

I actually just built something similar, but it might be a few weeks before I post the Instructable.

In the meantime, here is one answer to this problem:

It ultimately comes down to what type of LED he is using. Once you know that, the rest of the things will be easier to answer.
