This isn't a folding light, but I plan to use it for my tent in hanging fashion.
I was at home depot the other day and found the grip light. Info on it can be found at:
Main features, is has 2 13w bulbs, which are enclosed and thus protected, and a sliding grip thing that grap onto other things to hold it into place.
Prices was around $29.00
And it's compact too, more slender and longer than the folding lights.
After opening it and playing with it for a few minutes I decided I need another one.
As far as the ott-lite, be careful where you buy it. Jo-anns has it but they want a small fortune for it (list price is near $100 and I think they try to sell it for $60). I picked a new one up on ebay for $30 or so and that had the magnifier piece too.
