I have found the "Ott" like lamps at Big Lots, Menards, and Walmart. I have two floor lamps, and three desk lamps. I use them for my quilting, reading, and my husband uses them for his hobby work. If someone can explain the difference between these bulbs and the "Ott" bulb I might consider spending $100 on a lamp. In the meantime I've spent $19 on the desk lamps and $39 on the floor lamps. Just a thought. :)
