The Amazon booklight draws power from the Kindle ... Oh, gawd - there goes any sanity when talking about battery life in the upcoming months.
Study One - Read five hours a day, LED lamp on for 45 minutes, take every-other-Tuesday off, adjust LED hours to daylight savings time ...
Although it has been pointed out that the Amazon product isn't priced way outta line, I'll stick with "atermarket" LED lamps and covers for a while.
