I don't know what the inside of every fixture in Home Depot looks like. You may be able to see a picture or description of the lamp on the box. Most Home Depot fixtures do not have double ended lamps like in the site you sent. Just look at the lamp in the fixture at HD and see what it looks like. You can't mix sodium with MH so be sure the fixture you buy is metal halide and not mercury or sodium. You should be able to get an aquarium suitable lamp for any HD fixture
