When Hancock's closed in my town and having the big sale, I was with other guild members at the sale and asked them why aren't you buying a bulb for your Ott lamp? Everyone said, my bulb hasn't burned out. ? I bought all the ott light bulbs they had after the manager said if I bought all of them I could have them for 90% off!!! I won't have to buy another bulb for my lamp at all, and have given several away. Now they are moaning about the bulbs being so expensive and won't bring their table lamps to workshops and sew days anymore thinking they may break a bulb. I toss my lamp in the car and don't have the hassle worrying about it or being short on cash for another one. The original bulb is still working!
