Have two lights, table and floor models. My floor model quit working and changing bulb did not help. My son-in-law (Mr. Fix-It) found that a chip (?) in the base failed. He called the company and they told him what he needed and sold/sent him the part. Cost was less than $20.

Love 'em. I have three in different places. My "getting old" eyes appreciate them.

I have three Ott floor lamps and love them. Used 50% off coupons @ JoAnns. I love them.
