Sierra Designs Night Glow Disc Attic
Ease of Setup: Pretty easy
Price Paid: about $20
I was skeptical how useful this would be and how bright.
It arrived, is very light, compact, and at night time I was impressed with the light output. You probably cannot read a book by the light, but it helps you get around and get settled.
Not sure how to replace batteries in the tiny lights, but hopefully I can figure it out when the time comes.
If you are going to buy a whole new tent set up, I suggest you get one of these and include it in the same shipping costs.
