On another note. When Hancock's was going out of business I bought all the Ott bulbs that fit my light fixtures at 60% off. Some were 75% off later on. A few dollars now instead of a lot of dollars later is a big savings. One customer told me her ott bulb was still working so she didn't need one. ? It's bound to burn out sometime. Bulbs are a consumable item. You will need more.
