$75 · 700w and 620 w airport runway lightbulbs

Cleaning out husband's shed. 8 VERY LARGE lightbulbs from airport runway inventory I assume. Not sure why we have them. He had tested them to see that they worked, but they do require full power - you cannot "dim" them and run at lower power. There are 8 all together, a mix of 700 and 620 watt, 120v. You are welcome to test before you buy if you have the equipment & means to do so. Price is negotiable if you find some don't work, I just have no way to do that for you. They are 10 inches long by 5 inches in diameter. First photo shows bulb beside a standard light bulb so you can see the difference :-) $75 for all of them, not each. Fun for art project or who knows what... They appear to be worth a lot of money: 700watt bulbs sold new here: https://www.interlight.biz/light-bulb/700PS40-220V-240V
