I LOVE my Ott Lite! I don't know how I ever stitched without it! I used to use the daylight bulbs, and for me the Ott is a BIG improvement. I have a floor model by my chair that is used daily for hours. It was gifted to me by a friend a couple of years ago when her MIL passed away. She didn't think she'd have any use for it, so it came my way (bless her heart!) I am still using the original bulb-at least two years old.
I love mine so much in fact, that I recommended it to my friend to use when grooming her dogs. Her light travels with her to the shows almost every weekend. It's a bit more bunged up than mine, but it's still going, and she loves it too!
