Letshugitout,
I love the cover. It does add weight, though, but it's not too bad. I knew I needed a light but not often as mostly I'm home. Didn't want to have to worry about having batteries at the last minute if I'm going somewhere. The case is $60 but that works out to the same price as buying a case and clip on light separately. I had a $30 gift card from buying the Kindle to use, so for me it was a no brainer. Not sure how much light comes from the clip on ones, but this did it's job. You can't move it around, but it was just the right amount of light for me to read and not disturb somebody. Hope that helps you.
